What are the symptoms of a faulty accelerator pedal position sensor?
1 Answers
The symptoms of a faulty accelerator pedal position sensor are: 1. No response when accelerating; 2. Slow acceleration; 3. Unstable idle speed. The working principle of the accelerator is: when the accelerator pedal is pressed, it directly controls the throttle valve, which increases the throttle opening, allowing more air to enter the engine. At this time, the ECU commands the fuel injection system to inject more fuel, increasing the engine speed and causing the vehicle to accelerate. Solutions for abnormal noise when accelerating include: 1. Replacing the engine oil; 2. Cleaning engine carbon deposits; 3. Replacing spark plugs; 4. Conducting a comprehensive inspection and repair of the vehicle.
