They may not clear the code.
I've had them do it twice before, but the last time I went in for a read and then asked them to clear, I was told it'* against policy and that they never have done it?!?!?
Proly depends on who'* doing it and all.

After my recent UIM experience, the car is running fine but the wife came in and told me her check engine light came on 
....
A quick trip to AZ showed a double P0401 error code.... after reading through the threads (I especially liked camljr
) it occured to me that it seemed to happen to more than a couple of fols right after an UIM change. What do you think about it being a vacuum leak at the UIM? I've seen the couple of o-ring missing threads.
I'm gonna try and clean it up, check the connections, etc... but just wonder about a different vacuum leak.
