CEL P0401 Low EGR flow. How do I clean the EGR passage?
1997 Honda Accord Question: CEL P0401 Low EGR flow. How do I clean the EGR passage?
I replaced the EGR and the CEL is still on. When I removed the old unit there was thick black carbon build up. Could someone provide me step by step directions on how to clean the passage so air can flow. Thanks - patelhardikk
