Fuel Pressure Sensor A Circuit Low

Where it lives

For P01C5, the sensor sits on the circuit this code reports. The description of P01C5 reports a fault at the sensor.

Check these first

• A short to ground on the fuel pressure sensor A signal wire
• A failed fuel pressure sensor A
• Low fuel pressure from a weak pump
• Corrosion at the sensor A connector
• A faulty ECM input for sensor A

What to do next

1. Read fuel pressure sensor A on a scan tool
2. Test the sensor A signal wire for a short to ground
3. Inspect the sensor A connector and wiring
4. Check the fuel pressure against spec
5. Replace fuel pressure sensor A if it reads low
6. Clear the code and retest
