What is MID 23:

MID 23 refers to an issue with the Exhaust Gas Recirculation (EGR) System. The ECM detects a malfunction in the EGR system, which can result in poor engine performance, increased emissions, or engine stalling.

Why This Happens:

  • Faulty EGR valve.
  • Shorted or damaged wiring in the EGR circuit.
  • Blockages or contamination in the exhaust system affecting EGR function.
  • Loose or corroded connectors.
  • ECM failure to process EGR system data.

How to Fix It:

  1. Inspect the EGR valve and its wiring for damage or malfunction.
  2. Test the EGR system to ensure proper function.
  3. Clean or replace the exhaust system components if needed.
  4. Replace the faulty EGR valve if necessary.
  5. Ensure that the exhaust system is functioning without blockages.

How to Avoid It Before It Happens:

  • Regularly inspect the EGR valve and wiring.
  • Perform routine maintenance on the exhaust system to prevent contamination.
  • Keep connectors clean and free from corrosion.
  • Monitor EGR system performance with diagnostic tools.
  • Clue’s Equipment Maintenance services help monitor EGR valve health and prevent issues before they affect engine performance.
