What is CID 190:
CID 190 refers to a problem with the engine's exhaust system, specifically with the exhaust gas recirculation (EGR) system. The ECM detects that the EGR valve is malfunctioning, potentially leading to increased emissions, poor fuel economy, or engine performance issues.
Why This Happens:
- Faulty or malfunctioning EGR valve.
- Carbon buildup in the EGR valve.
- Shorted or damaged wiring in the EGR control circuit.
- Blockages in the exhaust system.
- ECM failure to process EGR data correctly.
How to Fix It:
- Inspect the EGR valve for carbon buildup or malfunction.
- Test the EGR valve for proper operation.
- Clean the EGR valve if necessary.
- Check wiring and connectors for damage or corrosion.
- Replace the faulty EGR valve if necessary.
How to Avoid It Before It Happens:
- Regularly clean or replace the EGR valve to prevent carbon buildup.
- Inspect exhaust components and the EGR system for contamination.
- Keep connectors clean and free from corrosion.
- Perform diagnostic checks to monitor EGR valve performance.
- Clue’s equipment maintenance services track exhaust systems and help prevent issues before they affect engine operation.
