P1125 Meaning

The Accelerator Pedal Position (APP) sensor 1 and the APP sensor 2 are potentiometer type sensors, each with the following circuits:

• A 5-volt reference circuit

• A low reference circuit

• A signal circuit

The control module provides the APP sensors with a 5-volt reference circuit and a low reference circuit. The APP sensors then provide the control module signal voltages proportional to pedal movement. The APP sensor 1 signal voltage is low at rest and increases as the pedal is depressed.

The APP sensor 2 signal voltage is low at rest and increases as the pedal is depressed. When the control module detects that the APP sensor 1 and the APP sensor 2 signal circuits are out of correlation with each other, DTC P1125 sets.
