Table Of Contents

    Description of DTC code P1280 Generic

    The Accelerator Pedal Position Sensor (APP) is an electronic device that, as the name implies, is intended to monitor the position of the accelerator pedal. On top of the throttle, support is the TAC (Throttle Control Actuator), where 3 throttle position sensors are installed, which have individual signal and reference circuits. It is worth mentioning that the signal of this sensor changes according to the position of the throttle, which tends to be higher when the pedal is depressed.

    The storage of the fault code P1280 OBDII means that an incorrect operation has been detected by the Accelerator Pedal Position Sensor 2. Being a specific code, you should consult the vehicle’s information source, in order to know the application given by the manufacturer.
