P1125 Chevrolet Code - Accelerator Pedal Position Sensor Fault
Quick Answer
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. Common causes include Faulty Accelerator Pedal Position Sensor, Accelerator Pedal Position Sensor harness is open or shorted, Accelerator Pedal Position Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1125 Chevrolet Description
• 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.
What are the Possible Causes of the DTC P1125 Chevrolet?
- Faulty Accelerator Pedal Position Sensor
- Accelerator Pedal Position Sensor harness is open or shorted
- Accelerator Pedal Position Sensor circuit poor electrical connection

APP sensor fault, I Had a P1125 fault about a year ago and I changed the sensor, It lasted about six months and went out again, so I bought a new one and this time it only lasted one week. I cleaned connectors and the wiring seems to be in good shape. any ideas anyone? Thanks.
