EGR Valve (Question)
My egr valve works and we just put a new gasket on it but the Check Engine light still hasn't gone off.. does this PCM need to be reset or should it automatically detect that its working now? Also could the problem be down wind of the EGR valve like the 02 Sensor or some build up in the pipeing? Thanks for all posts,

Aaron, What was the original code? Some DTC'* will clear after so many start cycles where the PCM no longer detects the problem that initiated the DTC. Or you need a Tech II (Dealership) to clear the DTC. Will the Actron code readers clear codes? Anyone know? Remove power from the PCM for a few minutes will reset the PCM.

The original Code was DTC P0401 = "EGR Flow Snsufficient" than a little bit down it says, "Mil REQUESTED, Since IGN NOT RUN, Since Clear P/F" so what exactly does that interput into? Thanks,

Yeah, its not at fault took it to a shop had it tested, and watched the valve open and the 2nd test it passed as well, so im guessing hte pcm just needs reset and if it comes up again then i know there is another problem else where. Thanks,
