P0102 Maf Code

[TTZ06]

97 Tahoe 4X4
350

I bought this truck throwing this code as well as others. Took apart the maf and it was coated in mud. Cleaned and replaced sensor. Code still there. I went further and tested the voltage on the pink wire, good. Tested for ground, good. Hooked up my scanner and read on average of 5-6 gsec at idle.

Is that a good reading for these trucks or is the maf just bad and not registering enough flow?

should be about 2 g/s at idle clean again, make sure screen is not damaged and not thermistors are missing.

^ What he said..

I just had to replace my sensor, after my CAI install. I attempted to clean it, checked all the meter readings and everything checked out, but still wouldn't stop throwing a code, replaced it and haven't had an issue since.
