I searched on this topic and had some results but now im at a stand still. I need to not have any stored obdII codes Im running olsd I have solve all but one of my problems. The MAF code. Evey time I put all the maf codes to not report the car doesn't run it just dies turn them on to a,b,c and the car runs like it does everyday. What gives? Anyone figure this out yet? I need to pass my OBDII plug in test. I just failed god dam it. :bash:

The PCM fails over into SD when any of the MAF DTC's are reported.

If MAF DTC's are marked "not reported" then the PCM will never failover into SD.

Ok I understand that But, How does one go about passing the emissions plug in test?

Thanks for the reply

How does it run with a Maf? Would it be a PITA to install one?

For what it's worth, I disabled the reporting of the bad knock sensor on my 2000 and it passed the California plug in test with flying colors.
