The power unit of almost any modern car has a throttle valve. Over time, the mechanical regulator of the valve flow area, which changes the amount of medium flowing in the channel - liquid or gas, becomes clogged and because of this the car begins to behave strangely. In this article we will talk about what ailments can be caused by a clogged throttle body in a car, as well as how to properly clean the throttle body on a Toyota Corolla.
As a rule, with a clogged damper, the engine speed of any car begins to fluctuate slightly, it ceases to be sensitive and swings its speed from one extreme to another; the second reason may be an increase in fuel consumption. Agree, not one motorist will want to have increased fuel consumption and reduced power of his friend. And finally, the end of everything can be the moments when the car simply starts to stall. When this happens, you should really think about the fact that you need to clean the throttle valve.
Okay, what is a throttle body anyway?
Let's remember the principles of operation of the combustion chamber in an engine.
Fuel enters the chamber, which needs to be ignited, and in order for it to start burning, it needs to be mixed with air. This is where the throttle valve comes in: it regulates the amount of air entering the engine and allows a small amount of energy to be consumed at low speeds. If you press the gas pedal, the amount of incoming fuel will increase, and, accordingly, you need to increase the amount of air so that the fuel burns more efficiently. Then the damper opens and air is sucked into the engine from the atmosphere. In an ideal world, where there is no low-quality gasoline, no dust and all technical regulations are observed, the throttle valve would not need to be touched at all. But we live in rather harsh conditions for engines, so due to a lack of tightness in the car’s air system and a weak fuel filter, carbon and dirt can settle on the throttle, which sometimes need to be cleaned off. If you do not do this, the damper will begin to stick, and because of this, starting the engine may be difficult, and the speed will fluctuate.
Therefore, if you have already traveled more than tens of thousands of kilometers, then it is worth, at least for the sake of interest, to trust the master and clean the throttle. In most cases, the effect of cleaning is immediately felt.
How to clean
Every specialist in a specialized car service knows how to properly clean the throttle valve, but not every car owner. But it is recommended to perform this procedure at least 30–50 thousand km, depending on the quality of the fuel used, the condition of the filters and systems.
You can clean the throttle valve without removing the valve or by removing the part. In the first case, an intake valve cleaner is used. First, the air duct is dismantled, after which, with the damper closed, the product, which is usually released in the form of an aerosol, is applied to the surface of the part. Dirt and oil accumulations are removed with a soft cloth. Next, you need to open the damper (press the gas pedal all the way) and remove dirt from the side surfaces and channels. The procedure is performed several times.
Please note that partial cleaning, as well as washing the injectors without removing them, will not completely remove all contaminants from the part. Therefore, it is better to carry out the procedure with removing the throttle.
Complete cleaning
Complete cleaning of dirt and carbon deposits is only possible when the device is removed. The correct way to dismantle the unit is as follows:
- Disconnect the air duct.
- Remove the damper by unscrewing the bolts and disconnecting the connectors.
- Using a carburetor cleaner or a special compound for throttle valves, use a soft cloth to thoroughly wipe the part inside and out.
- Repeat the cleaning procedure several times, avoiding strong mechanical impact, which can lead to removal of the protective coating of the metal, damage to the damper itself and its position sensor.
- After cleaning the throttle, reassemble the entire air supply system assembly in the reverse order.
- “Train” the damper after installation by setting the idle speed to the required (factory) value.
How to clean the throttle position sensor
Contamination can also get onto the position sensor. Due to malfunction of the sensor, loss or poor contact, the information received by the vehicle's ECU about the position of the part will be incorrect. As a result, the engine will not gain speed - or, more dangerously, the throttle will open completely while driving, which will lead to an increase in speed instead of braking.
Use a liquid and a soft cloth to remove dirt and oil deposits from the sensor without using excessive force.
How do you know when it’s time to clean the throttle?
You can visually assess the condition of the throttle yourself by moving the throttle to a vertical position by pressing the accelerator pedal, and you will need the help of a friend. Or remove the throttle and examine its condition, but we will talk about this in a few paragraphs. Many car enthusiasts rely on indirect signs - the engine does not start as quickly as before, the idle speed fluctuates or the dynamics disappear altogether and the speed “hangs” at the same level. If you have collected at least two points, it is better to address this issue. Otherwise it may come back to haunt you in the future.
How much does cleaning cost at a car service center?
When cleaning yourself, the costs depend only on the cost of the selected liquid. As a rule, this amount is around 100–500 rubles, depending on the manufacturer and store.
The technician will tell you how much it costs to clean the throttle valve at a service center after preliminary diagnostics. Remember that the appearance of signs of contamination does not mean that only cleaning is required - there may be malfunctions of the air and fuel supply unit. Therefore, it is impossible to give an exact price without checking.
You can clean the car engine damper yourself, but if you do not have special skills, it is definitely better to contact the experts at a specialized car service center. In this case, you will definitely save time and will not be afraid of damage to the elements of the injection system, which you can cause by unqualified actions.
How do you usually clean the throttle body?
If we go the more painstaking and thorough route, we will need a screwdriver, a set of wrenches, carburetor cleaner and rags. Yes, yes, carburetor cleaner, even if you have an injection car. Historically, carburetor cars were first invented, which also required timely cleaning. Therefore, chemists came up with a carburetor cleaner that perfectly dissolves all the slag that has accumulated in it. Since the nature of the origin of the deposit is the same for both carburetor and injection cars, the name “carburetor cleaner” has stuck around.
Tools and cleaning products
First, we need to decide on tools and cleaning products. We will need a brush, rags, a special cleaning agent for the carburetor - you can buy it at any car store, it would be a good idea to have a liquid like WD-40, a small brush and the rest of the tools that will be useful for removing this valve from the Toyota power unit.
Having found all of the above, you can drive the car into the garage and confidently begin the task at hand. So, let's start looking at the step-by-step instructions for cleaning the throttle valve.
Let's return to the story of cleaning the damper.
- Remove the air system pipe leading from the air filter to the throttle body.
- Unscrew the throttle valve mounting bolts.
- Disconnect the throttle position sensors.
- That's it, the throttle is in your hands. Be sure to cover the intake manifold with a rag to prevent dirt from getting in there.
Just a small matter: spray carburetor cleaner on the choke. For example, we used a product from Astrohim. It does not have a pungent odor and does a good job of dissolving deposits on the damper. Let the mixture soak in a little and start scrubbing away the plaque.
But! Do not use any abrasive materials when cleaning the valve and generally do not overdo it with friction force. This way, you risk removing useful deposits and losing the tightness of the system or disrupting the smooth operation, causing the damper to move jerkily.
After the procedures are completed, install everything in reverse order.
Removing the throttle body 1NZ-FE
The throttle body is located in the engine compartment between the power unit, battery and cooling radiator. To dismantle it you will need to perform the following steps:
Unscrew the air filter housing and disconnect the pipe
- We find the BDZ under the air and cooling pipes, we begin operations to obtain the necessary space for access to the device;
- Initially, a thin hose is disconnected directly from the unit being dismantled;
- Next, remove the large air pipe. To do this, you will need to loosen the two fastening clamps using a ten-point socket and remove the hose coming from the breather;
- The 1NZ-FE throttle valve changes position due to the connected gas pedal cable. To disconnect it, you will need to unscrew two nuts with a 12 mm spanner and remove it from the seat;
- Unclip the two latches and remove the top cover of the air filter, moving it to the side. To obtain a larger stroke, it is necessary to disconnect the power cables from the two air vent sensors;
- Next, dismantle the lower half of the air filter housing. It is secured with three bolts. We unscrew them using a ten-point socket and an extension;
- Subsequently, we remove the lower part along with the connected inlet pipe. It will be more convenient to disconnect it from the fastener located on the headlight unit. You will need to use a ten key. It is enough to unscrew one of the two bolts on the fixing bar;
- We take out the dipstick from the gearbox, disconnect the power connector for the throttle position sensor and the idle air valve motor;
- We remove the fastening strip of the gas pedal cable by unscrewing two nuts with a 12 mm wrench. It is moved to the side without disconnecting the wiring;
- To gain full access to the BDZ, it remains to disconnect the tube for inserting the dipstick into the gearbox. It is fixed with two 10mm bolts. After unscrewing them, the tube is pulled out by slightly lifting it up. You don’t have to do this step, but getting access to the remote sensing block will be problematic;
- The final step is to unscrew the last 12 bolt that secures the throttle unit. After this, nothing will prevent you from removing the unit from the power unit.
We disconnect the wire connectors, finally unscrew the gas pedal cable.
If you have any problems with unscrewing the bolts and nuts, you should use WD-40. The liquid is applied to bolts or nuts that cannot be unscrewed.

Hello, please tell me what viscosity oil you are using 5W30??
@Sergey Rybkin thank you
5W30 Liqui Moly Molygen.
I did all the same, same procedures. I just changed the spark plugs. The rpm is 1500 when hot, I don’t know what to do. The motor is the same
Thank you! Helped a lot
Good afternoon, tell me what could be? Yesterday I started the car, the revs disappeared, before they were 650-800 and now even during warm-up it’s at 100-300 Mark2 1gx100 also clean the throttle?
In the intake manifolds, you only cleaned what is immediately visible, but how much dirt is there inside? And there’s a lot of it there too. And by the way, the damper needs to be checked for clearance
Cleaned the throttle valve and injectors, after that it dials 3 thousand and gives a cutoff
A gap appeared on the throttle valve
Why didn’t you show me how it was before? I can also start the car and say it started working great
@Sergey Rybkin no, well, THAT needs to be done, of course, and the mark is good, it’s clear that they take care of the car
Yes, that’s almost what happened. Only now I know that everything is fine with me there. The revs rose a little, then went back to where they were.
I have 600 rpm when it's warm and in D when you stand there is vibration in the steering wheel, today I disassembled the throttle and will clean it with the handles
Your rpm on a warm engine should be approximately 600-700, but not 1100
650 rpm there should be. You even have a sign on the hood indicating the rpm
@Sergey Rybkin 600 is normal. My 600-700 seem to be idle. On the motor. which was brought from Japan.
After driving for an hour, they became 800. 600 is not enough.
The Russian people always masturbate fate with their own hands. Why bother with the throttle if it works fine? And then the whining begins: the revs fluctuate, etc.
If I hadn’t climbed there for a couple of years, then I would have wondered why the engine was bad. No one has probably cleaned it since birth.
Friend, do you have a Bems motor? If so, can you answer me why my car sometimes jerks when starting to move and when you start moving, it turns off sometimes, as if the speed drops, cutting when you press the gas and the engine stalls ((. I mean the engine ((((why can you explain this if it’s not difficult. Thanks in advance.
How did you unscrew the idle air valve? 3 bolts. The screwdriver is already stripping the thread
@Sergey Rybkin Is there a pentagon there?
I cleaned the throttle too well that a gap appeared around the damper, you can see it in the light, which is why the revs are high. Now the flap does not close all the way.
This is a gap XX, it should be here
Dude, you need a gopro camera, both hands will be free.
It hums and periodically creaks from the engine, then stalls, sharply lowering the speed. Please tell me if you have any guesses
awesome) explained everything clearly - I’ll have to clean it myself too)
hello Sergey, skills or Bems motor problem, gearbox, cleaned the throttle valve and the gearbox is foaming in D, do you advise?
Hello. Can you tell me what the problem might be, the engine is the same as yours. When starting cold, the rpm is stable at 850 and during the warming up process it rises to 1400. ?
Hello, how did you solve the problem?
This is a normal phenomenon in cold weather, so that the engine does not become unstable, this happens on 3 engines of different cars
It’s the same for me. Have you cleaned the dz? Has anything changed?
You should wear a lapel, otherwise it’s very hard to hear
Well, did the revs drop or is it still holding 1000 -900. There is no vibration because the speed is high..
Guys, please tell me why when I start the car the revs rise to 700, and sometimes it stalls, and in order to get into the warm-up modes you have to press the pedal to the floor so that the revs slowly rise. Motor 1 Jfe
Died xxx change the throttle completely
Temperature sensor or whatever it is.
Good day Sergey, like for the video and the work, I also have such an engine on the brand and this is what I began to notice, this has never happened before, when a cold engine picks up the warm-up speed poorly, it shakes and there is a stench of gasoline, as if it is throbbing, then it warms up everything seems to be normal, only sometimes the revs can fluctuate a little, especially after switching from D to P, give me advice if you know where to dig, it’s just that everyone who doesn’t hear the word beams says what did you want, it’s such a capricious motor, I’ve been riding it for 5 years, no problems, oil every 7000 thousand km 5/30 synthetics, filters, spark plugs all on time

Errors when cleaning
When deciding whether to clean the throttle assembly, you should remember the main mistakes car owners make.
So, what not to do?
Disassemble the damper in any unclear situation
Try to clean the assembly without dismantling
Use rough brushes instead of soft materials
Do not pay attention to adjusting the speed of the unit after cleaning
Remove the special coating applied by the manufacturer to the inner walls of the housing and the damper itself
Apply too much force as this may damage the damper and the adjacent sensor.
Step-by-step cleaning instructions
You can clean the damper with special aerosols (LIQUI MOLY DrosselKlappen-Reiniger (LM5111), Mannol Carburetor Cleaner, ABRO Carb&Choke Cleaner (CC-220)), that is, carburetor cleaning agents (carb cleaners). You can also use available materials (thinner, acetone, gasoline or WD-40). Many of these products have an aggressive chemical composition, so it is best to carry out manipulations with rubber gloves. Before cleaning, it is necessary to disconnect all rubber elements from the throttle body, otherwise there is a considerable risk that the selected product may damage them.
- It is necessary to clean not only the damper itself, but also the entire throttle assembly, including the additional air intake channels.
- For cleaning, you can use a regular brush; especially heavy dirt is best removed with a soft-bristled cloth. Metal brushes and coarse rags cannot be used, as they can damage the molybdenum layer on the surface of the assembly.
- Ideally, you need to apply the product for 10-15 minutes, then use a brush to remove it along with the carbon deposits. After rinsing, you should repeat the operation - apply the cleaning agent again, wait a while and remove it along with the dirt.
- After removing deposits, the assembly can be reassembled in the reverse order. First, you need to return all the rubber elements of the throttle assembly to their place, then install the idle speed regulator, then mount the assembly in place using a fixing bracket. Finally, install the air filter housing, then connect the air duct pipe.
Ideally, in addition to the cleaning agent, you can use a can of compressed air. It can be used to blow through all the channels and holes of the unit, which are difficult to access with a brush. Also, before installing the throttle assembly, it is advisable to replace the damper gasket with a new one, fortunately, it is inexpensive.
Review of the throttle body on the Toyota Corolla 120 and the approximate cost of the unit
The original Toyota Corolla 120 throttle body has article number 2203021030. The cost of a new product is high and can reach 45-50 thousand rubles.
For this reason, there is a wide selection of branded components from auto dismantling yards on sale. When purchasing a throttle valve removed from a car, the owner cannot be sure of its long-term and flawless service. Therefore, many drivers are inclined to buy analogues of the original product. At the same time, the price is usually lower, and the quality is in no way inferior to branded spare parts. The best throttle options for the Corolla 120 can be found in the table below.
Table - List of analogues of the original throttle valve for Corolla 120
| Manufacturer's company | Article number | Approximate cost, thousand rubles |
| OSSCA | 14336 | 12-14 |
| AISAN | THR321030 | 9-11 |

You should wear a lapel, otherwise it’s very hard to hear
Well, did the revs drop or is it still holding 1000 -900. There is no vibration because the speed is high..
Guys, please tell me why when I start the car the revs rise to 700, and sometimes it stalls, and in order to get into the warm-up modes you have to press the pedal to the floor so that the revs slowly rise. Motor 1 Jfe
Died xxx change the throttle completely
Temperature sensor or whatever it is.
Good day Sergey, like for the video and the work, I also have such an engine on the brand and this is what I began to notice, this has never happened before, when a cold engine picks up the warm-up speed poorly, it shakes and there is a stench of gasoline, as if it is throbbing, then it warms up everything seems to be normal, only sometimes the revs can fluctuate a little, especially after switching from D to P, give me advice if you know where to dig, it’s just that everyone who doesn’t hear the word beams says what did you want, it’s such a capricious motor, I’ve been riding it for 5 years, no problems, oil every 7000 thousand km 5/30 synthetics, filters, spark plugs all on time
