What I've found out is that if you do a repair to fix a CEL or MIL code and reset the OBDII by removing power from the system (i.e. Anyone out there know where I can find out, or how long this will take? The dealer could not help with the "Drive Cycle" information. Drive cycles are unique and specific to each automoble manufacturer." "To set the monitors to 'Ready', the vihicle must complete its appropriate DRIVE CYCLE (my emphasis). The booklet the state guys gave me mentioned something about Again, the advice to just drive it for a while. The only thing we could figure out was that in one of the modes he checked, the catalyst and evaporative system showed "No Reading". The mechanic did an OBDII check for me and let me watch the results, and everything was OK.
So I drove around for about and hour on local roads and on the highway with several shutdown/start sequences included, as well as numerous stop lights, changes of speed, etc. The car sat the rest of the night, and this morning I drove to the state Emissions testing site and got Rejected! due to Catalyst and Evaporative System readings of NOT READY.ĭrove to the dealer for advice, the mechanic said they normally just drive it for a while up to 40-50 MPH with a couple of stops, and turn it off and on a couple of times.
Did the negative battery terminal removal/replacement thing like my mechanic told me, started it up and Whoopee!, no CEL. I read a post that explained how to remount it in a more accessible spot). Ended up buying the parts and doing the job myself, still cost $300, plus the 1/4" extension to reach the VSV from the passenger side wheel well (what a poor choice of places to put what I now realize doesn't need to be hidden there. Had them wait, as it was running fine, no flat spots on acceleration or hesitation or stalls.
Dealer got a P0401 code and recommended changing the EGR, Modulator, and VSV for about $600.
