1 Answers
Volkswagen Lavida reports pedal position sensor fault. The possible causes include sensor interface failure, circuit short to ground, sensor failure, electronic control module (PCM or ECM) failure, etc. Accelerator pedal: The accelerator pedal, also known as the throttle pedal, is part of the automobile fuel supply system. By controlling the pedal travel, it regulates the engine throttle opening, controls the air intake, while the computer controls the fuel quantity, thereby adjusting the engine speed. The accelerator pedal position sensor detects how much the pedal is depressed, and the computer uses this signal to control the throttle motor to rotate a certain angle, meeting the air intake requirements under various working conditions. Operation method of accelerator pedal: The throttle of a car engine is generally controlled by the pedal, also called the accelerator pedal, which is the device for controlling fuel supply in vehicle engines. When operating the accelerator pedal, the right heel should rest on the floor of the driver's compartment as a pivot point, with the sole gently pressing on the accelerator pedal, using the flexion and extension of the ankle joint to press or release. When pressing or releasing the accelerator pedal, the force should be gentle, achieving smooth and gradual movements.
