If your car is experiencing idling problems, rough running, or poor fuel economy, the throttle body sensor (TPS) may be the culprit. The TPS is a crucial component of the engine management system, responsible for monitoring the position of the throttle valve and relaying that information to the engine control unit (ECU). A faulty TPS can lead to a range of performance issues, so it’s essential to replace it promptly if you suspect it’s malfunctioning.
Replacing the TPS is a relatively straightforward process that can be completed in a few hours with the right tools and a bit of mechanical know-how. In this article, we’ll provide you with a step-by-step guide on how to replace the TPS, including tips on troubleshooting and identifying the correct replacement part for your vehicle. By following these instructions carefully, you can restore your car’s performance and ensure smooth, efficient operation.
Before you begin, it’s important to gather the necessary tools and materials. You’ll need a socket wrench set, a screwdriver, a multimeter, and a replacement TPS compatible with your vehicle’s make and model. Once you have everything you need, you can follow the steps outlined in the following paragraphs to replace the TPS.
How To Replace Throttle Body Sensor
The throttle body sensor (TPS) is a vital component of your vehicle’s engine management system. It measures the position of the throttle valve and sends this information to the engine’s computer, which uses it to calculate the amount of fuel to inject into the engine. If the TPS is faulty, it can cause a number of driveability problems, including rough idling, poor acceleration, and increased fuel consumption.
Replacing the TPS is a relatively simple task that can be completed in about an hour. Here are the steps involved:
- Disconnect the negative battery terminal. This will prevent any electrical shocks while you are working on the TPS.
- Locate the TPS. The TPS is typically located on the side of the throttle body. It is a black or gray plastic sensor with a three-wire connector.
- Disconnect the electrical connector from the TPS.
- Remove the two bolts that hold the TPS in place.
- Carefully remove the TPS from the throttle body.
- Install the new TPS. Reverse the steps above to install the new TPS.
- Reconnect the negative battery terminal.
- Start the engine and check for proper operation.

What are the symptoms of a faulty TPS?
The symptoms of a faulty TPS can include:
- Rough idling
- Poor acceleration
- Increased fuel consumption
- Stalling
- Check engine light
How can I test the TPS?
There are a few ways to test the TPS:
- With a multimeter: You can use a multimeter to measure the voltage between the TPS’s signal wire and ground. The voltage should change smoothly as you open and close the throttle valve.
- With a scan tool: You can also use a scan tool to read the TPS’s output signal. The output signal should be a smooth, increasing voltage as you open the throttle valve.
How much does it cost to replace a TPS?
The cost to replace a TPS will vary depending on the make and model of your vehicle. However, you can expect to pay between $50 and $200 for the part and labor.
