What fault can a damaged throttle position sensor cause?

The throttle body position sensor can be used to detect the opening of the throttle body to judge the working condition and load degree of the engine.

A throttle body opening signal can be provided for an automatic transmission vehicle. The throttle body position sensor is a friction piece,

It is also a wearing part. When it or the circuit is defective, the following faults will occur:

1. When the vehicle is running, the engine is easy to stall, and it is difficult to start or start the car.

This is the most common fault of throttle body position sensor.

2. The engine is unstable at idle speed, with intermittent jitter during acceleration, slow response and high and low speed.

Occasionally, there will be short circuit or open circuit, which is also caused by the fault of throttle body position sensor.

3. Inappropriate installation and adjustment of the throttle body position sensor resulted in the idle switch not being turned off when the throttle body was completely closed.

Or the idle switch is still closed when the throttle body has a certain opening.

4. The sliding contact of the linear variable resistor has poor contact, and during the process of the throttle body from fully closed to fully open,

The output signal of the throttle body position sensor is interrupted intermittently.
