What are the symptoms of a faulty throttle position sensor?

[DeJayce]

The manifestations of a damaged throttle position sensor are as follows: 1. Poor contact of the idle speed contact; 2. No idle speed signal, the engine has no idle speed or unstable idle speed, poor contact of the no-load contact, and no full-load signal input. The reasons for the failure of the throttle position sensor are as follows: 1. Poor contact: The connector is corroded, resulting in poor contact, low voltage or no conduction, causing the engine to stall easily or have difficulty starting. 2. Initial position misalignment: This leads to excessively high or low output voltage, causing unstable idle speed, either too high or too low. 3. Coating failure: This causes resistance changes, leading to inaccurate output voltage, resulting in jerky vehicle starts and poor acceleration. 4. Excessive carbon buildup at the throttle: This causes incomplete closure, affecting the output voltage and flow values, leading to inaccurate air-fuel ratio and unstable idle speed.
