What is the performance when the throttle position sensor is broken?

The damage of throttle position sensor is characterized by poor contact of idle contact, no idle signal, no or unstable idle speed of engine, poor contact of no-load contact and no full load signal input, which will lead to low engine speed and difficult acceleration. Computer adjusts injection and ignition time according to throttle opening! If the throttle valve is damaged, the engine computer will not work normally.

The damage of throttle position sensor is characterized by poor contact of idle contact, no idle signal, no or unstable idle speed of engine, poor contact of no-load contact and no full load signal input, which will lead to low engine speed and difficult acceleration.

Computer adjusts injection and ignition time according to throttle opening! If the throttle valve is damaged, the engine computer can't receive the throttle opening signal correctly, resulting in inaccurate adjustment of fuel injection quantity and ignition time, and in severe cases, the engine may not be started!

What is the cause of the throttle position sensor failure?

1. The rusty joint, poor contact, low voltage or non-conduction make the engine easy to stall or difficult to start.

2. The initial position is inaccurate, and the output voltage is high and low, which leads to unstable idle speed and high and low.

3. Spray painting fault, the change of resistance value leads to inaccurate output voltage, and the vehicle starts to rush, resulting in poor acceleration.

4. Too much carbon deposits on the throttle valve and its lax closing affect the output voltage and flow rate, resulting in inaccurate air-fuel ratio and unstable idle speed.

What are the symptoms when the throttle position sensor is broken?

Damage to the valve position sensor will lead to engine jitter and unstable idle speed. The most obvious symptom is unstable idle speed. When you accelerate very fast, you will feel that your motivation is not strong or you can't accelerate. In severe cases, you may not be able to start the engine.

The throttle position sensor is also called throttle opening sensor or throttle switch. Its main function is to detect whether the engine is idling or loading, accelerating or decelerating. Essentially, it is a variable resistor and several switches, which are generally installed on the throttle body.

The throttle position sensor is a friction component and a vulnerable component. If the throttle position sensor is damaged, two problems will occur:

First of all, the car idling is unstable because the sensor detects the real-time condition of the engine through two contacts. Once there is a problem, the idle speed will be very unstable.

Second, the car won't start. Even if it is started, it is often closed.

If you often encounter these two situations, it means that the throttle position sensor is broken, and the owner needs to replace the sensor in time to avoid other unnecessary effects on his car.
