Where is the throttle body sensor located?

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.

How do you change a throttle position sensor?

Your throttle position sensor should be attached using electrical connectors. These connectors are easy to remove using the tab on the side. Once the electrical connectors are removed, look for the mounting screws on your sensor. Carefully unscrew and remove your throttle position sensor.

What are the symptoms of a failing throttle position sensor?

What happens when a throttle body sensor goes out?

Your engine might stall, idle slowly or misfire when your car is stopped. The car might accelerate itself, hesitate to accelerate, or lack power when you are trying to accelerate. You may also experience difficulty in changing gears.

How much does it cost to replace a throttle body sensor?

The average cost for throttle position sensor replacement is between $157 and $201. Labor costs are estimated between $55 and $69 while parts are priced between $102 and $132. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

How To Replace and Adjust the Throttle Position Sensor

What is difference between throttle body and throttle position sensor?

The TPS checks the amount of air/fuel mixture being delivered to the engine, while the throttle body temperature sensor monitors the temperature of the air/fuel mixture and the actual throttle body.

Can I replace throttle body myself?

If a scan tool is not needed then it could be done right at the location. If you have the proper mechanical skill set you can replace your throttle position sensor yourself.

What causes throttle body failure?

Possible causes of a malfunction

One of the main causes of a malfunctioning throttle body is internal contamination. Due to the contamination accumulated in the throttle body, the throttle valve can no longer move properly, causing problems with the control of the air supply.

How do you reset a throttle body?

Leave the key off for a moment, turn the key to the "On" position again, wait 3 seconds, and press the accelerator 5 times in 5 seconds. Wait 7 seconds, and hold the accelerator down. The check engine light should start blinking, continue to hold pedal down until it stops blinking. You can then start the car.

How do you test a throttle body sensor?

Testing it involves grounding the connectors' terminals as you put the multimeter probe on black to negative and red to positive. Make sure the throttle is fully closed by turning the key without starting the vehicle. Then read the voltage. The TPS voltage should be between .

Does throttle position sensor affect transmission?

The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.

How do you diagnose throttle body problems?

Does a throttle position sensor need to be programmed?

Code errors can cause your throttle position sensor to work erratically or incorrectly. Otherwise, you'll need professional software to reprogram your sensor.

What fuse controls the throttle body?

The power provided to the electronic throttle actuator is regulated by the actuator relay in the underhood fuse panel. It acts as a switch, sending power to the throttle actuator when it is required.

How often does a throttle body need to be replaced?

How Long Does a Throttle Body Last? While you should clean your throttle body at least once every 75,000 miles, a throttle body that's properly cared for can easily last 150,000 or even 200,000 miles. That's because it's a mechanical component, and it takes a while for mechanical components to wear out.

How long does it take to replace a throttle body?

How long does a throttle body replacement take? The job usually takes around an hour for either a replacement or a cleaning.

Is it better to clean or replace a throttle body?

While throttle-body cleaning is good preventative car maintenance, it should also help engine drivability. In fact, if you've noticed a rough idle, stumbling initial acceleration or even stalling – all when the engine is fully warmed up – a dirty throttle body could be the culprit.

What should be performed after replacing an electronic throttle body?

Since the throttle body is now clean, the engine must readjust to the higher increase in airflow that is no longer obstructed by the dirty throttle body. After allowing the engine to idle for several minutes, turn the engine off.

How much does it cost to clean throttle body?

RepairPal.com suggests that a throttle body cleaning costs between $226 and $290. What's interesting to note is the price of parts: $6 to $12, the low estimate of which is about twice the cost of a can of CRC Throttle Body Cleaner at your average auto parts store.

How many sensors does throttle body have?

The accelerator position sensor is made up of two individual sensors, with both sensors designed to have individual sensor return wiring.

Which sensor is located in the throttle body or intake manifold?

The MAP sensor is typically located on the intake manifold, either next to or on the throttle body itself. (On a forced-induction engine, the MAP sensor can be found on the intake tract before the turbo.)

What is the code for throttle position sensor?

The most common throttle position sensor code is the P0122 – Throttle Position Sensor/Switch A Circuit Low Input. It's triggered when the ECU detects that the TPS circuit A is outputting a lower voltage than expected.
