What is MID 146:
MID 146 refers to a problem with the Exhaust Gas Recirculation (EGR) Valve. The ECM detects that the valve is malfunctioning or the circuit is open, which can affect exhaust gas flow and reduce engine efficiency, increase emissions, or cause engine stalling.
Why This Happens:
- Faulty EGR valve.
- Shorted or damaged wiring in the EGR circuit.
- Blocked or contaminated exhaust system affecting EGR operation.
- Loose or corroded connectors.
- ECM failure to interpret EGR valve data.
How to Fix It:
- Inspect the EGR valve and wiring for visible damage or malfunction.
- Test the EGR valve to ensure it is functioning properly.
- Check the wiring and connectors for damage, corrosion, or loose connections.
- Replace the faulty EGR valve if necessary.
- Inspect the exhaust system for blockages or issues affecting EGR performance.
How to Avoid It Before It Happens:
- Regularly inspect the EGR valve and wiring.
- Keep the exhaust system clean and free from contamination.
- Perform routine maintenance on the EGR system.
- Monitor EGR system performance using diagnostic tools.
- Clue’s Equipment Maintenance services ensure proper exhaust system function and prevent EGR issues before they impact engine performance.
