Fault code 14 on 1KZTE

Reliability, efficiency, and comfort of the Toyota Corolla are ensured by many components, the most important of which is the electronic self-diagnosis system (SS) for the technical condition of the car. It “reports” error codes, which are then used to determine specific serviceability.

Engine fault codes 1.3 1NR-Fe

Corolla fault codes cover the most important parts of the car. The system can operate in two modes: normal automatic and forced. In automatic mode, it informs the user about problems that have arisen during the operation of the vehicle. In the forced mode, the user himself, using special procedures, calls from the system information about the technical condition of the node he is interested in. Here we will look at the procedure for self-diagnosis of the Corolla, and start with a brief description of the CC.

“Temper” of error and “behavior” of the motor

When the car has one ignition coil, then if it breaks down, you will not be able to drive further until the problem is fixed or replaced. But since modern engines have as many of them as there are cylinders, you can still go some way with this error. However, the engine will start:

• triple and this problem will only continue to grow;
• do not “feel” the gas pedal, i.e. the speed will not increase and may even fall;
• when it rains, the tripling will be greater;
• in the cold since the start.

Basically, ignition coils can fail when:

• installing bad spark plugs that allow breakthrough of reverse gases and breakdown of the insulator, which is bad for the insulators of the ignition coils;
• overheating for a long time if the cooling system is faulty or the fuel mixture is very lean. It also ruins the spark plug tips and coil electronics.

What error 14 Toyota can lead to:

• melting of the gas catalyst-neutralizer;
• rapid wear of the motor mounting pads due to high vibration;
• excessive fuel consumption, loss of power and engine efficiency.

Diagnostic connectors Corolla 120, 150, 180

Corolla anti-theft fault codes

Error codes on the diagnostic connector DLC 2 of Corolla 120, 150, 180 are supplied in OBD II format. In OBD format, codes are encrypted with 5 characters: the first literal character and the next four numeric characters. The literal character of this code indicates the node where the problem occurred:

The following numbers indicate the exact location of the breakdown, as well as its classification.

Additional systems fault codes

Diagnosis of OBD II error codes is possible only with special scanners or by connecting connectors to a computer with special software. After receiving the Corolla codes, fault diagnosis is carried out using a table describing the error codes and their corresponding defects.

“Fighting” error 14

There are a number of ways to install a non-working coil:

• if the engine is running rough, then by disconnecting the coil connectors, you can notice either a decrease in speed (the part is intact), or they will remain the same (defective part);
• On the removed coils, measure the resistance of the windings; usually faulty ones have a sharply different resistance. And a spark plug paired with a damaged coil is usually wet and black with soot;
• Sometimes a car’s self-diagnosis can show which cylinder is not working when the “Check engine” indicator is on.

Auto centers identify faulty parts using motor scanners that analyze vehicle electronics.

Troubleshooting (misfire) may be related to the coil tips. In this case, they must be replaced immediately. Otherwise, it may even break through the control transistor or short-circuit the secondary winding.

The malfunction of the coil itself is often associated with its primary winding, which requires its replacement. In this case, it is necessary to ensure complete insulation of the wires.

Catalog numbers

These important components of the Toyota ignition system (like all others) have a ten-digit catalog number. The first five are the same for all coils - 90919, the next five (usually written with a dash) are different, for example, 02117, 02163, 02234, 02259, 02265, etc.

Considering the important role that this module plays, it would be correct not to experiment with installing suitable coils on the machine, but to install only the one recommended by the manufacturer.

Location and types of diagnostic connectors

Cars of the Japanese manufacturer Toyota were equipped with two types of connectors that allow diagnostics - DLC1 and DLC2. More modern models use a DLC3 connector (standard OBD-II).

DLC1 is made in the form of a rectangle located on the left side of the engine compartment (in most cars of this brand). The plastic cover of this connector is marked Diagnostic.

Toyota errors can manifest themselves as follows:

• If a malfunction is detected in the engine, the Check Engine indicator on the instrument panel will light up.
• But if a breakdown occurs in the automatic transmission, the O\D OFF indicator will light up on the panel.
• The SRS light indicates a malfunction in the passive safety system (airbags, seat belt pretensioners).
• The ABS indicator lights up if there are errors in the operation of the anti-lock braking system.
• If the traction control system fails, the TRC lamp on the instrument panel will light up.

The DLC2 diagnostic connector in almost all cars of this manufacturer is located under the dashboard on the driver's side. Outwardly it differs from the first one. One of the features of this connector is the ability to diagnose a car on the go.

In earlier Toyota models, the diagnostic connector is located in the engine compartment. Typically, it is round in shape and yellow in color. It can often be found near the battery.

Modern scanners

Reading Corolla fault codes with scanners not only simplifies self-monitoring, but also makes it more informative. Today, manufacturers of diagnostic car scanners supply the market with a wide range of them, differing both in functionality and price. On the one hand, such a market is capable of satisfying the needs of various segments of consumers, but on the other hand, it creates certain difficulties, since it requires some special knowledge when purchasing. Here we will only indicate the main types of diagnostic equipment, as well as its purpose. And this will not be a bad guideline for choosing the right scanner. Based on functionality, scanners are distinguished between dealer, brand and multi-brand.

Corolla robot error codes

Dealer scanners are produced by automakers or their contractors, usually for a specific car brand. They have a wide range of functionality and are intended for professional use, and the price can reach several thousand dollars.

The group of brand scanners is also intended for professional use. They have functionality similar to that of the dealer, but more modest. The price of branded scanners ranges from several hundred to a thousand dollars.

Fault codes for automatic transmission and ABS Corolla

Multi-brand scanners are most widespread among motorists. They are easy to use and provide sufficient information for most situations. Scanners of this group are unified for several car brands. Therefore, when purchasing, you need to check their ability to read Corolla error codes.

Self-diagnosis - step-by-step instructions

Professional car diagnostics at a specialized service center is not cheap. In addition, many car owners simply do not have the opportunity to use such services, since they live far outside large cities, and they have no desire to turn to “garage” specialists.

In such cases, self-diagnosis methods come to the rescue. Only basic skills are needed, so even beginners can figure it out. For example, to check engine operation, the procedure is performed in the following order:

1. Open the hood and find the DLC1 connector with a plastic cover (look for the inscription Diagnostic). Open or unscrew the cover and find the contact markings on the back side. Use a paper clip or a piece of wire to connect terminals TE1 and E1.

If your car uses a DLC3 connector, you need to close contacts TC and CG.

1. Turn on the ignition and watch the instrument panel indicators. The Check Engine and O\D lights should blink. If they light up and go out at intervals of about 0.5 seconds 11 times or more, no errors have been detected in the operation of the engine and automatic transmission. On some cars, the Check Engine light may light up and go out repeatedly with an interval of 4.5 seconds, this is also a sign of normal operation of all internal combustion engine systems.
2. If you find that the indicator is reporting errors, you need to move on to the next section.

Proper diagnostics

Continuation of 1.3 Corolla engine error codes

The Toyota Corolla diagnostic system consists of sensors that record the physical parameters of components, an electronic control unit (ECU), a program for this unit, as well as a fault indication system.

Initially, the manufacturer entered the reference values ​​of the state parameters of the vehicle components into the ECU memory. During operation, the sensors record the actual values ​​of these parameters and then send them to the electronic control unit. The Corolla ECU compares the received actual parameters with the reference values ​​and, if they do not match, writes a code into memory. After this, the control unit sends an error code to the Toyota Corolla “CHECK” indicator light. When the fault is corrected, the error signal disappears. In addition, it is possible to force the reading of fault codes with or without a scanner.

Malfunctions of the 1.3 Corolla engine

On the light indicator, error codes are visualized by the number of light signals, as well as the combination of their length and pauses between them. Toyota uses two types of light codes: 09 and 10. 09 is a two-digit code. This means that it starts with the number 11 and ends with the number 99. The duration of the glow - pause is 0.5 seconds. The pause between tens and ones is 1.5 seconds, the pause between ciphers is 2.5 seconds, and between a series of ciphers is 4.5 seconds. For example, two glares with a pause of 0.5 seconds plus one glare after 1.5 seconds corresponds to 21 error codes.

Code 10 is a unique cipher. In it, the number of light pulses corresponds to the fault error code. Just like in the previous cipher, the duration of the lights - pauses is 0.5 seconds. In this case, the pause between ciphers is 2.5 seconds, the pause between a series of ciphers is 4.5 seconds. 12 glares in 0.5 seconds correspond to the 12th fault code error.

Engine fault codes 1.4 Corolla

During the operation of the Corolla, the need arises for forced diagnostics of individual components of the car. For this, three blocks of diagnostic connectors (DLC - DataLinkConnector) are installed: DLC 1, DLC 2, DLC 3. The DLC 1 connectors are assembled in a diagnostic box labeled “Diagnostic”, which is located under the hood at the rear wall of the engine compartment. Connectors DLC 2, DLC 3 are located inside the car on the driver's side. DLC 2 connectors are installed under the panel, and DLC 3 under the front door. The DLC 2 block is used to read information with special scanners.

Error codes for the 1.4 King engine

The DLC3 unit has very limited use; it can be found on Corollas with a robotic gearbox.

It should be noted that the location of the scanning blocks may vary slightly under the hood or in the cabin, depending on the make and year of manufacture of the car.

DLC 1 consists of 20 connectors designed for engine and transmission self-diagnosis.

1.6 Corolla engine fault codes

To open the lid of the box, just pull the visible petal. The standard diagnostic procedure is carried out using a scanner. But in the absence of a scanner, the necessary information at home can also be obtained without it. To perform this procedure, perform the following diagnostic steps:

Corolla 1.6 engine malfunctions

If it blinks more than eleven times with an amplitude of half a second, then this indicates the absence of errors in the ECU memory, as well as the serviceability of the machine. This encoding corresponds to the 09 cipher. If “CHECK” blinks with an amplitude of four and a half seconds, it means that the car uses code 10 and it is also working.

Engine 1.6 Fault codes

And if the signals are different, it is necessary to read the code, determine the type of malfunction from the code and, depending on this, take further action. Self-monitoring of other nodes is carried out in a similar way. Only blocks of components and pairs of connectors, as well as indicators on the instrument panel, can be changed.

Toyota Corolla error codes

There is some experience with the most common Corolla error codes that can help resolve the problem. Often the CC registers code p0810 for the Toyota Corolla 2006 - 2009 gearbox, which indicates a general clutch position control error. The reasons may be caused by a breakdown of the actuator, TCM or travel sensor.

VSC and power steering errors

Trouble code p0900 in Corolla specifically indicates damage to the clutch actuator circuit. The reasons for the appearance of the p0900 signal are an open circuit in the wiring or failure of the Corolla clutch actuator motor.

Air conditioning fault codes

A series of similar errors p0351, p0354, p0352, p0353 Toyota Corolla indicates defects in the low voltage circuit of the ignition coils. These codes occur due to an open or short circuit in the IGF1 and IGT circuit between the ignition coils (1-4) and the ECM. To eliminate them, first the circuit is tested for a short circuit, then coils 1–4 are checked, if the errors do not disappear, the ECM is replaced.

Relatively often, the Corolla has a speed signal malfunction with code C1541. The error code may be caused by abnormalities in the speed sensor circuit, skid control ECU, CAN communication system, or power steering ECU.

Air conditioner errors

Code P0500 speed sensor signal on Toyota means that the automatic transmission engine control unit does not receive data about the speed of the vehicle. With this error, the Corolla goes into emergency mode. The reasons for the appearance of the code may be an open or short circuit in the speed signal circuit, a malfunction on the Corolla instrument panel, the skid control ECU, or the Corolla speed sensor.

Toyota automatic transmission fault codes

To read the codes, you need to count the number of times the O/D OFF light comes on with the ignition on and terminals TE1-E1 in the DLC1 connector (in the engine compartment) or TC-CG in the DLC3 connector (in the passenger compartment) closed. Check that upshifting is not prohibited (the O/D OFF indicator should not be illuminated).

Error codes for the SRS security system in Toyota cars

The codes are read with the ignition on based on the number of times the SRS lamp lights up. In connector DLC1, contacts TC and E1 must be closed, and in DLC3, a jumper is installed between pins TC and CG.

Error codes must be erased when the ignition is turned off. If the codes are stored in memory, follow these steps:

• connect two wires to pins TC and AB;
• turn on the ignition and wait at least 6 seconds;
• in turn, 1 time per second, close contacts TC and AB to ground with an interval between closures of no more than 0.2 seconds;
• after the third circuit, the TC light on the panel should flash quickly, which confirms that the codes have been deleted from the memory.

• 11/12/13/14 – short circuit or break in the driver airbag igniter circuit;
• 15/16 – short circuit or open circuit in the front SRS sensor circuit;
• 31 – failure of the security system control unit;

Electric power steering Self-diagnosis (how to read fault codes) 1. Check the “P/S” indicator. Turn on the ignition and make sure that the indicator lights up and goes out after 2 seconds. 2. Reading fault codes (without using a scanner). a) Jumper the terminals “TC” and “CG” of the DLC3 connector.

b) Turn on the ignition. c) Read the fault codes by the number of flashes of the “P/S” indicator. Notes: — If there are no faults, the indicator blinks continuously at a frequency of 2 times per second.

— If there is a malfunction, after a pause of 4 seconds, the codes begin to be displayed. — The indicator flashes 1 time per second. The first sequence of flashes corresponds to the first number of the diagnostic code, consisting of two numbers. After a pause of 1.5 seconds, a second sequence of flashes is displayed, corresponding to the second number of the code. — If there are two or more fault codes, the output between them is set to an interval of 2.5 seconds. The display will start from the lowest number and continue upward. — After a pause of 4 seconds, the codes are displayed again.

3. Erasing fault codes (without using a scanner). a) Jumper the “TS” and “CG” pins of the DLC3 connector. b) Turn on the ignition. c) Within 8 seconds, disconnect and connect the jumper to the “CG” terminal at least 4 times. d) Make sure that the normal code is displayed. e) Remove the jumper.

4.

Hello people! I know that now you will all start kicking me in the stomach and sending me to a search engine. But I was already there and no matter how hard I tried I couldn’t find any error codes. Maybe if it’s not difficult for anyone to post a link to error code number 14.

Shaved What's the problem? Does not start?

This code means that when the starter rotates (or when the computer thinks that the starter is rotating), the computer does not receive a signal from the ignition coil control unit.

Somehow the retractor wire came off the starter, I turned the key, the computer thought that the starter was turning the engine and wondered why there was no signal from the crankshaft speed sensor. As a result, I found and fixed the problem, forgot about it and went about my business, and a month later, after doing a self-diagnosis, I discovered code 13 in my memory.

@Shaved

And the problem guys is this: Completely out of the blue, while driving I felt that the engine began to openly stall. More like five to be exact. I was surprised, because I had recently changed the spark plugs, and since I was driving slowly around the yard, I turned on N and hit the slipper a couple of times, it seemed like he had screwed up. Then I went out onto the highway, accelerated to 90, drove for a while, it started to shake again, but it really did, because it already had a sound when I stopped, like a tractor, and it didn’t shake sourly. At the same time, the check light came on, and the turn off light came on, for some reason it also came on. After standing like that for some time and revving up, they went out, the engine also seemed to work. I drove on (I was not at home, I was driving from the village), then while driving, everything started again, the engine light came on, no luck. When you press the floor, the traction completely disappears and the engine almost stalls. then everything returns to normal again, it starts to drive normally, then after a while the light goes out. I've put it on hold for now and won't drive it again until I figure it out. Today I did a self-diagnosis, it showed error number 14, I have no codes. I couldn't find it in the search engine. Here’s another thing: several times I left the car overnight in the yard, and since my signaling system was broken, I pulled out the EFI relay overnight just in case. Repeatedly. Could something be causing this?

Sincerely . Shaved.

Damn, does no one really know what error number 14 means?

there is one in the FAQ. Plus this week we were discussing code 14. Why rub the same thing 10 times? I wish I could find it. If you haven’t found it, then you don’t really need it.

Added after 3 minutes 25 seconds:

Yes, everyone knows.. and they answered you once already.. how much do you need? ))

PS First of all, you need to decide on the car. or Tourer V or JZX91. otherwise these are slightly different engines.

@Shaved

So, in order:

2. Would you like to find it? You know, not everyone apparently knows how to use the notorious FAK about which I know nothing.

3. Answered. But there are a lot of abbreviations, and I didn’t understand what I wrote about.

4. If everyone knows, what is so difficult to repeat? I haven’t visited this site for half a year, and now I’ve noticed that the more people there are, the worse it gets. No one had ever screwed up like this before. Maybe ask the Honda drivers, maybe they will be kinder and answer.

5. Engine 1GZ-GTE body JZX-91, what’s unclear here?

the very first topic.

I didn't understand. Do you want to repair it yourself or will you go to a service station? and Phantom wrote to you without abbreviations.

not difficult. the control unit does not see the signal from the coil/coils. You can at least ask Kalinovodov. )

Shaved To be honest, I don’t fall for it, but they already answered.

You better tell me what YOU don’t understand from

@Shaved

I think it’s worth starting by inspecting all the *chips* of the wiring. In general, since you don’t understand anything, it’s better (and perhaps cheaper in the future) to contact a service station.

@ Shaved @ Shaved @ Shaved

this is the name of the pins on the ECU connector

Added after 1 minute 35 seconds:

@Shaved

You're confusing, there's a coil for each spark plug. And about the computer. Damn, if you check the above connectors, as I understand it, you need to remove the panels in the cabin? The computer is hidden under the panel.

Added after 5 minutes 19 seconds:

And again, what Phantom wrote to me is a completely different opera. What does the starter have to do with it? And he talks about the 13th error!

I gave error 13 just as an example. So to speak, I developed the topic based on my life experience. By this I wanted to say that a fault code does not always indicate exactly the fault it indicates, and its appearance can be triggered by a simple coincidence or a combination of other faults. At that time, I did not know the whole history of your problem (by the way, if I were you, I would have started the first post with this, so that those responding would have full control of the situation). Considering the details you provided, you can forget about my story about error 13 - this is definitely not your case.

Now directly in your case. The decoding of the code says verbatim exactly what Zenya wrote:

I looked at the decoding for the 80th body, there is a slightly different wording. With your engine, as far as I understand, something like the following happened: at some point the computer, for some reason, stopped seeing one or more ignition coils, at which time the cylinder (cylinders) served by this coil (coils) did not work (did not work) , then the signal from the coils appeared and the cylinders started working, but the code was already written into memory, then the signal disappeared again. All this is very similar to a weak contact in the connector or a break in some wire. To begin with, I would try to remove the connectors from the coils, clean everything, put them back and check. If it doesn't help, climb further. The crankshaft revolutions here play a role not so much for a person as for a computer: it’s just that at high revolutions the error would not have been recorded or would have been recorded, but something else. And further. If the electronics on the 1JZ-GTE in the 90th body are arranged in the same way as in the 80th, then the computer has 7 IGF pins: IGF, IGF1, IGF2, IGF3, IGF4, IGF5, IGF6.

The ignition coils on the 1JZ-GTE are assembled with spark plug holders and look like “knobs” in their upper part. Chips with thin wires are connected to these “knobs”. Accordingly, each spark plug has its own coil. Therefore, there is no need for a distributor and high-voltage wires: there is simply no need to distribute high voltage across the spark plugs and supply it from the coil to the distributor, from the distributor to the spark plugs; it is “born” directly above the spark plug.
