The throttle position sensor (TPS) is a device that tells the car’s computer how far the throttle is open. This information is used to control the fuel mixture and ignition timing. A dirty or malfunctioning TPS can cause a number of problems, including:
- Rough idle
- Hesitation when accelerating
- Engine stalling
- Check engine light
If you are experiencing any of these problems, it is a good idea to have the TPS cleaned by a mechanic. Cleaning the TPS is a relatively simple procedure, but it is important to do it correctly to avoid damaging the sensor.
Instructions on how to clean the TPS:
1. Park your car on a level surface and turn off the engine.
2. Locate the throttle body. It is usually located on the intake manifold.
3. Disconnect the electrical connector from the TPS.
4. Remove the screws that hold the TPS in place.
5. Carefully remove the TPS.
6. Spray the throttle body cleaner on the TPS and a rag.
7. Wipe the TPS clean with the rag.
8. Reinstall the TPS and tighten the screws.
9. Reconnect the electrical connector.
10. Start the engine and check for any problems.
Be careful not to overspray the throttle body cleaner, as it can damage the sensor. If you are not comfortable cleaning the TPS yourself, it is a good idea to take your car to a mechanic.
Here are some of the reasons why it is best to have the TPS cleaned by a mechanic:
- Mechanics have the specialized tools and knowledge necessary to clean the TPS properly.
- Mechanics can ensure that the TPS is cleaned thoroughly and that all of the dirt and debris are removed.
- Mechanics can test the TPS to make sure that it is working properly after it has been cleaned.
