Toyota Errors P1603 P1604 P1605

On all modern Toyota/Leхus, these errors can be found in the engine ECU, in variation with other errors. Sometimes they hang in the memory, but the check does not light up.

Here's an example of what the manufacturer suggests checking for these errors.

P1603 Engine Stall History

After starting the engine, this DTC was stored when the engine was stopped without using the ignition switch. Using a hand-held scan tool, you can check the conditions at the time the DTC was set using a fixed set of parameters. The data of a fixed set of parameters reflect the state of the engine at the time of detection of a malfunction. This information may be useful in troubleshooting. Before starting diagnostics, you should check to see if the fuel is completely empty, as this DTC is also set when the engine stalls due to lack of fuel.

P1604 Startability Malfunction

This DTC is stored when the engine does not start even though the STA signal is output, or the engine takes a long time to start and the engine speed is low, or the engine stalls immediately after starting. Using a hand-held scan tool, you can check the conditions at the time the DTC was set using a fixed set of parameters. The data of a fixed set of parameters reflect the state of the engine at the time of detection of a malfunction. This information may be useful in troubleshooting. Before starting the diagnosis, you should check to see if the fuel is completely exhausted, as this DTC also remains when the engine starting problem is due to exhaustion of fuel.

P1605 Rough Idling

This DTC is stored when the engine speed drops below the threshold level. Using a hand-held scan tool, you can check the conditions at the time the DTC was set using a fixed set of parameters. The data of a fixed set of parameters reflect the state of the engine at the time of detection of a malfunction. This information may be useful in troubleshooting. Before starting diagnostics, you should check to see if the fuel is completely exhausted, as this DTC is also stored when the idle speed becomes rough due to fuel exhaustion.

As a rule, they are accompanied by more serious errors, for example, the fact of this is the screenshot below. Toyota Raf4 3ZRFAE Valvematic malfunction.

Causes of error P1605

On our resource you can ask questions and share your own experience in troubleshooting problems associated with error P1605. By asking a question within a few days you will be able to find the answer.

Taking into account the fact that OBD2 errors in the operation of the engine or other electronic systems of the car do not always directly indicate a non-functioning element, and the fact that for different brands and models of cars the same error can arise as a result of a malfunction of completely different elements of the electronic system, we have created this algorithm for assistance and exchange of useful information.

We hope, with your help, to form a cause-and-effect relationship for the occurrence of a particular OBD2 error in a specific car (make and model). As experience has shown, if we consider a specific make and model of a car, then in the vast majority of cases the cause of the error is the same.

If the error indicates incorrect parameters (high or low values) of any of the sensors or analyzers, then most likely this element is working, and the problem must be looked for, so to speak, “upstream”, in the elements whose operation is analyzed by the sensor or probe.

If the error indicates a constantly open or closed valve, then you need to approach the issue wisely, and not thoughtlessly change this element. There may be several reasons: the valve is clogged, the valve is jammed, the valve receives an incorrect signal from other faulty components.

Errors in the operation of the OBD2 engine and other vehicle systems (ELM327) do not always directly indicate a non-functioning element. The error itself is indirect evidence of a malfunction in the system, in a sense a hint, and only in rare cases a direct indication of a faulty element, sensor or part. Errors (error codes) received from a device or scanner require correct interpretation of the information, so as not to waste time and money on replacing working elements of the car. The problem often lies much deeper than it seems at first glance. This is due to the fact that information messages contain, as mentioned above, indirect information about the disruption of the system.

Here are a couple of general examples. If the error indicates incorrect parameters (high or low values) of any of the sensors or analyzers, then most likely this element is working, since it analyzes (produces certain parameters or values), and the problem must be looked for “upstream”, so to speak, in elements whose operation is analyzed by a sensor or probe.

Another point that I would like to note is the specifics of a particular brand and model. Therefore, if you recognize an error in the operation of the engine or other system of your car, do not rush to make hasty decisions, but approach the issue comprehensively.

Code P1248

Error P1248 often occurs when the gas recirculation system is clogged. Both EGR valves can fail at once, which happens when the mileage exceeds 100 thousand km .

EGR cleaning on Land Cruiser 200 SUVs is carried out already at around 50-75 thousand, although you can simply turn off the valves and disable this function at the program level. The procedure for shutting down the system does not require significant budget injections, but it is time-consuming.

Error P1349

And so, the mobile drove off, error 1349 no longer appears, the clutch works as expected, smooth gear shifting and power are back to normal.

What was the matter?

From the rhetoric: 1. The fact was that 98% of repairmen do not read the instructions 2. Because they do not read the instructions - they do it on a hunch and we get this kind of trouble 3. The oil pressure in my mobile was almost 2 points at idle , on a warm engine - this is more than decent pressure 4. There were no electrical problems, the wiring rang, the valve clicked, the other sensors were also normal 5. The installers did not comply with the regulations for installing the VVT clutch on the camshaft

From the specific: Stupidly supplying 12V. on the VTT valve, the car should stall, or drop the speed significantly - if this does not happen, then you need to look at 3 things (and this is true both for an old clutch, which can stupidly jam over time, and for a new one but CROSSLY installed) 1. Listen to the VVT valve - it should click when 12V is applied to it, this is noticeable, which means it is activated, in extreme cases you can pull it out and apply power to it separately to make sure that it is working, if it is very old or “crappy”, then it is better to change it - the price is 1500 rubles. – if everything is OK, we move on. 2. Measure the oil pressure in the internal combustion engine - compare with the instructions, if everything is normal, move on. if it’s not normal, we’ll look at why the pressure has dropped (but that’s another topic, in my case the pressure is normal) 3. Now you’ll need to remove the valve cover (I also removed the windshield to get to the chain and see the tensioners, how they were installed, just in case) loosen the chain and remove the camshaft with the VVT 4 clutch. I was unlucky, in 2 persons, I barely unscrewed the bolt from the clutch so as not to damage the camshaft - that is, they really tightened it from the SOUL, but only 54 Nm is needed, this is also not a small effort, but nevertheless, if suddenly someone wants to stretch it by hand, drive it in the neck, and stock up on a torque wrench (I did just that, fortunately the key turned up not very expensive, it’s useful in the household, but in a service station such it wasn’t. regrettably) 5. Now regarding the installation - here is the technical bulletin (https://www. aera. org/ep/techbulletins. 012/TB2587.pdf) - which I BELIEVE 100%, and this is also written in Toitovsky English manual, but who would read it. and even there are no pictures, and here is another foreign forum, which also guided me on the right path https://www. newcelica. org/forums/showthread. php? t=299052

What's special? - and the fact is that the VVT clutch needs to be UNLOCKED before installing it on the camshaft or make sure that it is UNLOCKED, the master also told me that he does not understand what the difference is in how to install it locked or unlocked - but after 20 minutes of brainstorming both before and before I was completely overwhelmed, I didn’t really understand either, but now everything is clear as daylight. The trick is that you need to attract, precisely ATTRACT the clutch in an unlocked state, I was unlucky, my clutch came locked when new, but someone is lucky, or the master is not no, yes, he will comply with the regulations (he will not overtighten the clutch), or he will just be stupidly lucky and the clutch will work, since NO ONE complies with these regulations - I understood this from analyzing data from the Internet - nowhere is what I wrote above written, here

And so, we continue the conversation - if you tighten the clutch in a locked state, there is a risk that the finger in it (which has the shape of a cone, you can see from the disassembled pictures of the clutch, fortunately there are plenty of them on the Internet) will get stuck and no amount of oil pressure will release it (and saying that the clutch blocked, etc., etc., they stubbornly sent me to the electricians, they seemed to know something about me, but apparently they wanted to cut off the money before telling me anything) - that’s why you need to first tighten the coupling in an unlocked state – one holds the clutch so that it does not snap into place – the other attracts it to the camshaft, and secondly the force is 54 Nm NO MORE – well, before installing it in the engine, you need to twist the clutch a little on the camshaft, check that it still moves and SNAP! then put it in the internal combustion engine and assemble everything.

Error p1238

When error p1238 appears on the Land Cruiser 200, pay attention to the operation of the injectors . Another option is to reduce the pressure in the fuel supply system . An indirect sign of a malfunction is rattling when starting the engine. The reason on an SUV is damage to the parts responsible for fuel injection. The malfunction may also be hidden in parts upstream of the fuel pump (dirt on the valves).

Communities › Toyota Club › Blog › TOYOTA AURIS error P1604((

Hello! Maybe someone can tell me. MINI VCI scanner for ToyotaTechstream V10.10.018 J2534 found error P1604. Deleted! she then appears again! Error P1604 - Startability Malfunction. In Russian this means “an unsuccessful attempt to start the engine.”

I read on the Internet they write: weak battery, poor quality fuel (I use 95th), the car has a Stop & Start system, they write it is probably from it.

Maybe someone can tell me
or don’t worry!

I apologize for the off-topic question, but I want to ask what did the author win by buying this device? I want to order one for myself, although the car drives without problems. Although there is one problem, the launch with the 2008 databases does not see it. The car itself is 2009. And the tree finds only a couple of incomprehensible sensors. But this does not affect the work, in fact it is curiosity. And I'm leaning towards the time-tested saying: if it works, don't touch it.

Error p0047

P0047 as a Kruzak 200 fault code again indicates a malfunction of the turbine elements . A complete replacement will be expensive, so the first step is to dismantle the working unit and clean it thoroughly. More often, the error occurs among owners of diesel Toyota Land Cruisers.

What does P0793 mean?

When shifting gears, the transmission shaft speed gradually increases until the desired shift point is reached. If the shaft speed does not gradually increase or if the PCM receives an erroneous signal from the countershaft speed sensor, P0793 will appear and the Check Engine light will illuminate. It should be noted that in some cars this indicator does not light up immediately, but only after the error appears multiple times.
