What is the phenomenon that the throttle position sensor fails?

The fault phenomena of throttle position sensor are: 1, idle speed is too high or too low; 2, the idle speed is unstable, and the idle speed is easy to turn off; 3. Engine jitter during acceleration; 4. Accelerate the response delay; 5. The engine appears intermittent jitter during operation. Fault reason of throttle position sensor: 1, short circuit or open circuit of idle switch; 2. Improper installation and adjustment; 3. The sliding contact of the linear variable resistor has poor contact. The throttle position sensor, also called throttle opening sensor or throttle switch, is installed on the throttle body. The throttle position sensor is a device used to detect the working state of the engine.
