What is CID 133:
CID 133 refers to a problem with the fuel system, particularly related to the fuel pump control module. The ECM detects that the fuel pump is not receiving the correct signals, which can lead to fuel delivery issues and engine stalling.
Why This Happens:
- Faulty fuel pump control module.
- Shorted or damaged wiring in the fuel pump circuit.
- Loose or corroded connectors.
- Power supply issues affecting the control module.
- ECM failure to interpret fuel pump data.
How to Fix It:
- Inspect the fuel pump control module and wiring for damage.
- Test the fuel pump to ensure proper operation.
- Check connectors for tightness and cleanliness.
- Replace the faulty fuel pump control module 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 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.
