Common Misdiagnosis
OBD2 Code: P025E
Description: Fuel Pump Module Control Circuit Low
Common Misdiagnosis: Replacing the fuel pump without checking for wiring issues or a faulty fuel pump control module.
OBD2 Code: P025F
Description: Fuel Pump Module Control Circuit High
Common Misdiagnosis: Assuming the fuel pump is defective when the issue may be due to poor electrical connections or a malfunctioning control module.
The codes P025E and P025F are ISO/SAE reserved, meaning they might not have standardized definitions across all manufacturers. Always refer to specific vehicle service manuals for accurate diagnostics.
Common Diagnostic Steps
OBD2 Code: P025E
Description: Fuel Pump Module Control Circuit Low
- Check for any blown fuses related to the fuel pump circuit.
- Inspect the wiring and connectors for damage or corrosion in the fuel pump module circuit.
- Test the fuel pump relay for proper operation.
- Measure voltage and ground at the fuel pump module using a multimeter.
- If necessary, replace the faulty fuel pump module or repair wiring issues.
OBD2 Code: P025F
Description: Fuel Pump Module Control Circuit High
- Inspect all related fuses and relays for signs of failure or damage.
- Examine wiring harnesses and connectors for shorts, opens, or corrosion in the control circuit.
- Use a multimeter to check voltage levels at the fuel pump module connector.
- Verify that there is no excessive resistance in the circuit by testing continuity.
- If needed, replace any defective components such as relays, wiring, or the fuel pump module itself.
