What is CID 885:
CID 885 refers to a problem with the fuel system, specifically the fuel pump relay. The ECM detects that the relay is malfunctioning, which leads to fuel delivery issues and engine stalling or failure to start.
Why This Happens:
- Faulty fuel pump relay.
- Shorted or damaged wiring in the relay circuit.
- Loose or corroded connectors.
- Power supply issues affecting the relay.
- ECM failure to properly interpret relay data.
How to Fix It:
- Inspect the fuel pump relay and wiring for damage.
- Test the relay to ensure it operates correctly.
- Check connectors for tightness and cleanliness.
- Replace the faulty fuel pump relay if necessary.
- Inspect the fuel system for any pressure inconsistencies or pump-related issues.
How to Avoid It Before It Happens:
- Regularly inspect the fuel pump relay and wiring.
- Perform routine checks of the fuel pump control system.
- Keep connectors clean and free from corrosion.
- Perform diagnostic checks to monitor fuel pump relay health.
- Clue’s fuel management services track fuel pump systems and prevent issues before they affect engine operation.
