What is the reason for the 2012 Focus not accelerating when stepping on the gas pedal?

[VioletRose]

The reason why the 2012 Focus does not accelerate when stepping on the gas pedal may be due to a failure in any of the three systems of the engine: intake, fuel system, or ignition, or other faults. The following is a detailed introduction to the reasons: Engine system failure: If the electronic throttle fault is ruled out, attention should be paid to the three systems of the engine: intake, fuel system, and ignition. Any component failure or abnormality in one of these systems may cause the situation where the car's throttle is fully pressed but the RPM does not increase. Car throttle pedal failure: There is a problem with the car's throttle pedal. When stepping on the gas pedal, the cable will drive the throttle, which is the accelerator. There is a position sensor on the throttle. The control unit learns the throttle opening degree according to the throttle position sensor signal, then calculates the corresponding signal voltage, and finally calculates the vehicle's fuel injection amount based on this signal voltage.
