DTC P1275: Accelerator Pedal Position Circuit (Sensor 1): Description

The Accelerator Pedal Position (APP) sensors 1 and 2 are located within the accelerator pedal assembly. Each sensor has the following circuits:

• A 5-volt reference circuit.
• A low reference circuit.
• A signal circuit.

This provides the Powertrain Control Module (PCM) with a signal voltage proportional to accelerator pedal movement. The APP sensor 1 signal voltage at rest position is about the low reference and increases as the pedal is actuated. The APP sensor 2 signal voltage at rest position is about the 5-volt reference and decreases as the pedal is actuated. When APP sensor 1 signal voltage is not within the predicted range, this code sets.
