ECU fault code 03 02
I replaced my EGR valve after receving this code. The CEL remained off for a few days but has since returned. The code is again 03 02.
Any ideas, anyone?. Is it the 0xygen sensors?

Re: ECU fault code 03 02
the hi/low flow lines are probably clogged with carbon buildup.(the brass colored lines running to and from the valve)Theier kinda hard to get to, but cleaning them out should solve your problem.

Ok - I will try that as soon as I can. I believe my miles per gal of gas has also dropped.
Thanks.
