BOB47 Posted December 26, 2007 Report Share Posted December 26, 2007 My engine is throwing a P0400 code. Says it's a bad EGR valve. I know where they were on older cars but where is it on our engine? Is it easy to change? Expensive? Thanks for any help. Also, will the check engine light go out when it's replaced or do I have to have someone clear it?

Bob that PO400 code is phantom code(according to AllData) with these trucks seeing how the 6.0 is not EGR equipped. I would give it a day or two and see if the SES light goes out, if all else fails you may need someone to clear it. Quote Link to comment Share on other sites More sharing options...

Autozone says they aren't allowed by law to clear it. Seems to be running fine. Guess I'll have to find someone to clear it. Quote Link to comment Share on other sites More sharing options...

zippy Posted December 27, 2007 Report Share Posted December 27, 2007 Just drive it a bit longer, it'll probably go off. It may be a problem from your O.S. that your previous tuner gave you. Quote Link to comment Share on other sites More sharing options...

Zippy, OK, I'm stupid. What's an O.S.? And previous tuner? PCMforless and you are the only people that have done any tuning on it. Quote Link to comment Share on other sites More sharing options...

Sorry, the trucks operating system. It's the factory tune used for the truck. The operating system for a truck is kinda like a Windows program for your computer. PCMforless is probably the one that put that O.S. on it assuming it was a standard mail order tune. If you can send me the pcm for a day, I can fix it.

If you can send me the pcm for a day, I can fix it. PM me the address you want it sent to. I've still got the original so I can swap them and send it to you. When I put the original one back in will I have to do the relearn procedure? Thanks for all the help Zippy. Quote Link to comment Share on other sites More sharing options...
