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

A car is made up of many precise parts, which work closely together. Many important parts, although small, have some problems that will affect the operation of the whole vehicle. Among them, the throttle position sensor, also known as the throttle switch, plays a very important role. As long as there is something wrong with the throttle position sensor, the car will not work normally. When the throttle position sensor is damaged, the following phenomena occur: 1. When the valve position sensor is damaged, the engine vibration and idle speed are unstable. The most obvious symptom is unstable idle speed. When you suddenly accelerate, you may feel that your motivation is not strong or your speed is not fast. In severe cases, you may not be able to start the engine. 2. The throttle position sensor is also called throttle opening sensor or throttle switch. Its main function is to detect whether the engine is in idle state, load state, acceleration state or deceleration state; 3. Essentially, it is a rheostat and several switches, which are installed on the ordinary throttle body.
