Honda Accord Check Engine Light on Due to Clogged EGR Ports
Honda Accord Problem
Model Year Affected: 2002
Average Mileage: 125,302 mi (124,000 mi - 126,605 mi)
I took my Honda to the AAA care care center and they removed the intake manifold and cleaned out the EGR ports and replaced all the gaskets. It took 3-4 hours. They reset the codes at that time. I have driven approx 20 miles now and the check engine light has not returned. When the codes were reset in the past the PO401 code would return after only 10-15 miles. So far so good.
Code P0401 - EGR Flow insufficient detected. I replaced the EGR valve, PCV valve, air filter and reset code. The code returned after driving 10 miles. AAA mechanic recommended removing intake manifold and cleaning EGR ports. I have not done this yet but will follow-up if that resolves the issue.
