So do CRD codes clear themselves after a couple driving cycles? Got some odd codes on my last read regarding fuel pressure (P0093) which is not unexpected given that I had replaced an injector and had a couple loose fittings afterwards that were weeping.

Cleared it and will watch for it to come back (P0672 glowplug #2 remains), but just wondering.

Yes, if the issue is resolved the codes should clear after about three driving cycles. If you fixed the fittings, and that was indeed the issue, then you're fine. Doesn't hurt to clear it with a scanner if you have one handy, though.

Didn't get the code you experienced.

Thanks, I think it has been more than three cycles (of course my office is only about 5 miles) but that is the first time I have seen that code and it hasnt reoccured. I have one of GDE's code scanners handy so I will just watch it and see if it reoccurs.
