Working on my girlfriends 2004 V6 auto and ive fixed most every code except this Code P0102 ‘MAF Circuit A Low’. Tested Circuits A, B, C, and D. The only circuit that i believe was out of spec was D, which had 13.7-13.8v. I read online its supposed to be .9-1.0v at idle and increase with RPMs but mine stays above 13v. If anyone can help with this issue, id greatly appreciate it!

Problem fixed. Turned out to be the ‘new’ MAF Sensor itself. Got a rebuilt one from CarQuest for $109 and the car runs just fine.

 

Oooof, for $109 it had better of worked...

 

F**k yeah it better work lol It would’ve been cheaper on RockAuto but we didn’t want to wait a week for shipping. Trans fluid and filter change yesterday, next up suspension!
