What to Do When the Throttle Position Sensor in a Car Is Damaged?

[VonAlyssa]

Car throttle damage's most prominent symptoms are engine shaking and unstable idle speed. When the throttle position sensor is damaged, it should be replaced promptly. Below are the steps to replace the throttle: 1. First, unplug the circuit connector on the throttle position sensor; 2. Use a short-handled Phillips screwdriver to remove the two screws securing the sensor; 3. Then remove the old sensor, install the new sensor, and tighten the two securing screws; 4. Finally, reconnect the circuit connector and conduct a road test after starting the vehicle. The reasons for throttle position sensor failure are as follows: 1. Connector corrosion, poor contact, low voltage or no conduction, leading to the engine stalling easily or difficulty starting. 2. Initial position misalignment, causing output voltage to be too high or too low, resulting in unstable idle speed, either too high or too low. 3. Coating failure, resistance changes causing output voltage misalignment, leading to jerky starts and poor acceleration. 4. Excessive carbon buildup at the throttle, preventing it from closing tightly, affecting output voltage and flow values, causing inaccurate air-fuel ratio and unstable idle speed.
