What is CID 22:
CID 22 refers to an issue with the vehicle's fuel system, particularly with the fuel pump control module. The ECM detects that the fuel pump is not receiving the correct signal, potentially leading to fuel delivery issues and engine stalling.
Why This Happens:
- Faulty fuel pump control module.
- Shorted or damaged wiring in the fuel pump circuit.
- Low or inconsistent fuel pressure.
- Power supply issues affecting the control module.
- ECM failure to process fuel pump data.
How to Fix It:
- Inspect the fuel pump control module and wiring.
- Test the fuel pump to ensure proper operation.
- Check connectors for tightness and cleanliness.
- Replace the faulty control module if necessary.
- Inspect the fuel system for pressure inconsistencies or blockages.
How to Avoid It Before It Happens:
- Regularly inspect the fuel system components, including the fuel pump.
- Perform routine checks of the fuel pump control system.
- Keep connectors clean and free from corrosion.
- Perform diagnostic checks to monitor fuel system health.
- Clue’s fuel management services track fuel pump systems and prevent issues before they affect engine operation.
