Late and tired so didn't fully read everything but honestly I would never ever ever diag MAF's with a basic DMM. You really need a scope to watch the curve.

Late and tired so didn't fully read everything but honestly I would never ever ever diag MAF's with a basic DMM. You really need a scope to watch the curve. Even with that it has to be fairly fast for some cars today, my old scope I had I car I absolutely knew it was the maf, I could just tell by the sudden fuel cut and then jump right at 2k rpm it had to have a drop out but my slow scope couldn't see it and now sadly that scope screen is deing so a PICO may be in my future but a DMM for maf, nah.
Keep in mind your scan tool baud rate is not as fast as your PCM inputs just an FYI. |
