Will the Barometric Pressure sensor cause a maf out of range code?
I have tried 3 different mafs-one new one but the code is still there. also replaced the o2 sensors and ait sensor-car is running rich.this just started last week as I had it sold till the light came on!

i guess it does-changed the bap sensor and car runs great with no light!

hmm... well cool! it's always good when you fix it on the first part. Yeah, the BAP sensor really affects engine operation a lot, a lot more than most people give it credit for. Basically, if you're at a high altitude, the air is less dense and the computer needs to correct for that; if the sensor breaks, the MAF might as well be useless because the computer can't trust the data it gets from it.
