What Causes No Response When Pressing the Accelerator Pedal with Only Idle Speed?
1 Answers
The reasons for no response when pressing the accelerator pedal with only idle speed: 1. Throttle cable issue; 2. Faulty throttle position sensor. The throttle has a position sensor, and the control unit determines the throttle opening based on the signal from the throttle position sensor, calculates the corresponding signal voltage, and then determines the vehicle's fuel injection amount based on this signal voltage. If the throttle position sensor is too dirty or the voltage is imbalanced, it may result in the vehicle not accelerating even when the accelerator pedal is pressed fully; 3. Poor signals from other sensors such as the air flow meter. It is recommended that the owner visit a repair shop to use a specialized diagnostic tool to read the vehicle's fault codes and perform repairs based on the fault codes.
