New maf sensor putting engine light one

Postby Chris205 » Mon Apr 14, 2014 7:07 pm

Why would a new maf sensor still be throwing up maf related codes?

Might not be the maf at fault, could be a blanked or leaking egr valve or boost leak, what is the actual fault code?

So if the maf is reading too high/too low then egr/boost fault.
If it says can't read from the maf(I'm not familiar with that tho) then you know that the maf is actually faulty.

P0102 MASS OR VOLUME (MAF / VAF) AIR FLOW SENSOR "A" CIRCUIT LOW

I would check plug/wiring.

Have your tried clearing DTC's after new sensor was fitted :?:

Broken wire or something I think. Use multimeter and check voltage etc.

Well after two new maf sensors bought another genuine ford one which is working faultlessly, I guess maf sensors have to be genuine, £200 from ford though
