P1125 BUICK: ACCELERATOR PEDAL POSITION SENSOR FAULT
P1125 CADILLAC, CHEVROLET: ACCELERATOR PEDAL POSITION SENSOR FAULT
The Accelerator Pedal Position Sensor (AAP) is a potentiometer whose resistance varies and sends a voltage signal to the ECM (Engine Control Module). The purpose of this sensor is to determine the position of the accelerator. The signal sent by these sensors is proportional to the movement of the pedal. The signal increases when the accelerator is opened.
The ECM provides the Throttle Position Sensors with a 5V reference circuit and a low reference circuit. If the ECM observes that the Throttle Position Sensor 1 and Throttle Position Sensor 2 have no correction in their signal circuits, the fault code P1125 OBDII will be set.
The reasons for setting the diagnostic code P1125 OBD2 are the following:
To solve the DTC code P1125 OBDII, take into account the following:
