What are the symptoms of a faulty throttle pedal sensor?

[McJayce]

The symptoms of a faulty throttle pedal sensor include the inability to generate a throttle opening signal to the ECU, causing the ECU to only inject fuel based on the intake air volume at idle. Below is additional information: 1. Throttle Pedal: The throttle pedal, also known as the accelerator pedal, is part of the vehicle's fuel supply system. By controlling the amount of pedal depression, it regulates the throttle opening of the engine, controls the intake air volume, and the ECU adjusts the fuel injection accordingly to manage engine speed. The throttle pedal position sensor detects how much the pedal is depressed, and the ECU uses this signal to control the throttle motor to rotate to a specific angle, ensuring the required intake air volume for various operating conditions. 2. Throttle Pedal Operation Method: The throttle of a car engine is typically controlled by the pedal, also referred to as the accelerator pedal, which is the device for regulating fuel supply to the engine. When operating the throttle pedal, the right heel should rest on the floor of the driver's compartment as a pivot point, with the ball of the foot lightly pressing on the accelerator pedal. The ankle joint's flexion and extension movements are used to depress or release the pedal. When operating the throttle pedal, apply gentle force, ensuring smooth and gradual movements.
