CEL code P0401- EGR Flow Insufficient
Posted: Thu Jul 15, 2004 9:00 am
Hey guys. My CEL came on in the avalon (I know, I know, this is a solara forum, but hey the engine is the same) while driving yesterday, so I took it to autozone to get the OBDII ran (which they do for free, by the way!!).
The code was P0401 - EGR Flow Insufficient
I ran a search and saw that a few people had this problem in the past. But from reading the threads, I couldn't figure out exactly what to do, so I thought I'd start a new one.
The guy at autozone says that the EGR valve is likely clogged from carbon buildup. The replacement part is a whopping 169.99. He said though, that I could take it off and clean it myself with some carb cleaner, and that might fix it. I was wondering how hard this is, and if anyone had any other opinions on what to do.
I don't know how many of you read my old post about the engine temp fluctuating drastically (normal while driving, very high while idle at a traffic light), but I think that this may be related. Any input is greatly appreciated. Thanks guys!
