What is a VW throttle body?

Last Updated: 25th February, 2020

The Volkswagen Throttle Body regulates the amount of air that flows into the engine. It is located between the intake manifold and air filter box. They are connected together by throttle linkages to obtain a better throttle response. The Idle Air Control Valve (IACV) is used to control the minimum airflow during idle.

Simply so, what does the throttle body do?

In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main.

Also, can you drive with a bad throttle body? If you have a bad throttle position sensor, your car will not perform well or safely. Driving with a bad throttle position sensor may also cause problems in other related systems in your car, which will mean additional repair bills.

Moreover, how much is a throttle body?

The average cost for a throttle body replacement is between $577 and $691. Labor costs are estimated between $92 and $117 while parts are priced between $485 and $574.

How can you tell if you have a bad throttle body?

When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle. This can include stalling when coming to a stop or very low idle after starting, or even stalling if the throttle is quickly pressed (resulting in the throttle body plate opening and closing very quickly).

Can a dirty throttle body cause a check engine light?

The check engine light can indicate many issues within a car including a faulty throttle body. Any problem detected with it will turn on the check engine light. As a part of your regular service intervals, include the air induction service and fuel injection flush to clean out any carbon deposits and dirt.

How do you know if your throttle body needs cleaning?

Signs of a dirty throttle body:
  1. Rough engine idle – The engine feels shaky while idling.
  2. Uneven engine acceleration – stuttering engine or slowed acceleration.
  3. Engine light comes on – “Check Engine” light turns on when the control module detects a problem in the throttle body.

How do you reset throttle position sensor?

Turn the ignition switch on and wait 3 seconds. Immediately after the 3 seconds, the accelerator pedal must be pressed and released 5 times within 5 seconds. Wait 7 seconds and fully press the accelerator pedal and hold for approximately 20 seconds until the check engine light stops blinking and stays on.

Do you have to program a throttle position sensor?

Code errors can cause your throttle position sensor to work erratically or incorrectly. Otherwise, you'll need professional software to reprogram your sensor. This job is best done by a professional mechanic. If your sensor just needs repairs, it could be the result of faulty or loose wiring.

Does cleaning throttle body make a difference?

In summary, you can clean the throttle body all you like, but the fact is, if your engine is worn, your intake and throttle body will continue to get dirty. Cleaning your throttle body likely won't do anything to solve an idle problem. It might make you feel better, but it might do little to solve an idle problem.

Does changing throttle body increase horsepower?

Because larger-spaced throttle bodies allow more air into the engine, several aspects of performance are improved. This gives the engine increased power and torque, which may be helpful in situations such as towing. Commonly, adding an aftermarket throttle body can increase engine power by 15 hp to 25 hp.

What happens if you disconnect throttle position sensor?

If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration. Correcting the TPS then produced a correct idle, and no code.

Is there a way to test a throttle position sensor?

The TPS connects to the throttle plate on the throttle body. So, without the correct signal coming from the TPS, you begin to notice drivability problems. Fortunately, it's not that hard to test the sensor. You can use the position sensor operating characteristics to test it using a digital multimeter (DMM).

Can I clean a throttle position sensor?

Cleaning the throttle body itself can be done using carburetor fluid and a clean cloth for the removal of light sludge. During this process, the throttle position sensor should not be cleaned due to the possibility of contamination or wire damage.

Where is the throttle position sensor?

A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle.

What should throttle position be at idle?

At idle is should be zero or a couple of degrees. Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open. You should see the percentage of throttle opening gradually increase to 100 percent at wide open throttle.

How does throttle position sensor work?

A throttle position sensor (TPS) is used to monitor the throttle valve position in internal combustion engines. TPS is usually located on the throttle valve spindle so that it can directly monitor its position. The sensor signal is used by the engine control unit (ECU) as an input to its control system.

Abdelfatah Katsevman


How do you adjust a throttle position sensor?

Loosen the throttle position sensor retaining screw with a Phillips-head screwdriver. Adjust the TPS by moving it back and forth until the voltage is between 4.0 and 5.5 volts. Hold the TPS in place and tighten the retaining screw with the Phillips-head screwdriver.

What is Throttle body alignment?

Throttle Body Alignment (TBA) This procedure cycles the motorized throttle body through various states (idle, part throttle, WOT) to relearn their positions. Some examples of reasons to perform a TBA: The vehicle's battery has been disconnected and re-connected. The ECU has been removed and reinstalled.

How do you diagnose a bad throttle body?

Symptoms of a Bad or Failing Throttle Body
  1. Dirt, grime, and carbon deposits on the inside of the housing. Dirt and grime can build up inside the housing, causing interruption in air/fuel flow.
  2. Electrical problems.
  3. Vacuum leaks or an incorrectly adjusted throttle stop.
  4. Poor or high idle.

Yihan Farto


Can a bad throttle body cause transmission problems?

The throttle position sensor can fail in several ways, all of which result in poor fuel economy at best, and performance limitations that may create a safety hazard for you and other motorists at worst. It can also cause problems when changing gears, or setting base ignition timing.
