Thread: MAF Low Voltage

Sure you can clean it, but I'd be looking into a possible wiring issue if it comes back.

Was a great help when I had a P0102, ended up with a bad MAF, bad MAF to PCM wire, and having a melted O2 harness. I probably had worse symptoms though; 12/13 mpgs, white smoke, coughing acceleration, reving idle, ect.

I had that a few months ago. After purchasing 2 MAFs and the problem still coming back after a week I found out my connector pins on the harness were corroded. Cleaned them up, add some dielectric grease and the problem hasn't came back.

I tried cleaning the old sensor and I checked the wiring before and that did not help.

I was going to send you the one I had for the cost of shipping your lose I guess.....

I'm putting money on that that is not an AC-Delco MAF if you got it that cheap. Cheap is not your friend when it comes to MAF's. So don't expect that thing to work/fix your problem. I'd buy Tonkins right away assuming it's an OEM one.
