Pedal Position Sensor A Circuit Intermittent

Where it lives

For P1135, the circuit described runs through the sensor. The description of P1135 reports a fault at the sensor.

Check these first

• A pedal position sensor A signal that cuts in and out
• A loose or corroded pedal position sensor A connector
• An intermittent open in the pedal position sensor A wiring
• A pedal position sensor A that drops its signal over bumps or heat

What to do next

1. Read pedal position sensor A on a scan tool while working the pedal
2. Wiggle the pedal position sensor A connector and harness
3. Inspect the pedal position sensor A connector for corrosion
4. Test the pedal position sensor A circuit for intermittent open and short faults
5. Replace the accelerator pedal assembly if the signal keeps dropping
6. Clear the code and retest
