SES light w/ code help

[sgtmac]

that big round one smack in the middle with the "ac" or "12" on it is the egr valve. something wrong with it?

That was the culprit, banged out a lot of the carbon, re installed and my SES went out, my idle is much smoother now too.

I would like to replace with a new EGR, unless you have a better idea!

Thanks

do not. at least not yet cleaning them is usually sufficient. are you are saying this is what was triggering the p0440 code? it should not have. in fact there are several codes as it relates to operational reliability and errors as well as if it get clogged up.

Not saying that is what caused it, but after disconnecting the battery, and cleaning it out, the SES went out and she runs a little better.

which didn't happen with the PCV or gas cap, maybe it was just dumb luck? Driven about 30 miles so far, no light, guess I will wait and see. Might go see if I'm still throwing a code that won't trip the light.

Thanks
