    I'm not sure if its my scanners limitations, but is there any way to find out PID (Parameter IDentification) called BARO (barometric pressure) in the PCM?

    The dealer diagnosed my MAF sensor as faulty due to mine reading 165 when it should be reading 158 for our area. I want to replace it myself and save myself $300 but I'm not sure how to find these numbers.

    Bump. I'm assuming this is a more difficult question for most on this forum...

    I think you would have to get into the PCM with tuning software to see something like that

    You need a scan tool that can pull live data to see PID's, usually that's out of reach for most enthusiasts unless they're tuning their own cars since tools to get data out of an OBD1 car aren't as cheap as the ones for newer stuff.

    Good thing it's a V6 so it's OBDII

    I can't access that info. Just the typical O2, MAF sensor, Coolant Temp stuff, etc. Might just be my scanner, might be the early limited OBDII system.

    Early OBDII is more limited in accessible data than EEC-IV in my experience.
