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.
