Does your car have a throttle position sensor limit too high code? Have you replaced the throttle body and gas pedal assembly but still get the same code? If so, you may have a faulty throttle pedal position sensor. In this blog post, we'll provide you with some information about the throttle pedal position sensor and how you can diagnose and fix the issue.

What is a Throttle Pedal Position Sensor (TPPS)?

The throttle pedal position sensor, also known as the accelerator pedal position sensor, is a vital component of modern electronic throttle control systems. It is responsible for sending a signal to the engine control module (ECM) that tells it how much throttle the driver is requesting. This signal can be in the form of a voltage or a digital signal, depending on the vehicle's make and model.

Diagnosing a Faulty TPPS

If your car is throwing a code for a throttle position sensor limit too high, the first step is to check the throttle pedal position sensor. You can do this by using a scan tool to read the codes stored in the ECM. Look for any diagnostic trouble codes related to the TPPS or accelerator pedal position sensor (APPS).

Once you've identified the code, you can test the sensor for continuity, resistance, and functioning. The sensor should provide smooth and continuous output signals based on the throttle input given by the driver. Any deviation in the sensor's reading could indicate that your TPPS is faulty and needs replacement.
