Lb7 p0102 dtc

Truck decided to throw the engine light today, getting a code for maf sensor p0102 and another for my sending unit which I know about.
Anyways before today it didnt have the engine light on, once the p0102 code showed up the light keeps coming back on no matter how many times i turn it off.
Truck has the factory intake, week old fram air filter, moonshine tune. Cleaned the maf with a Q-tip and rubbing alcohol, tightened the clamps on the intake and the light still comes on. Any other ideas? 2001 lb7 zf6

Log the maf and see whats going on. Could be a faulty Maf. With EFI you can scale it and even turn off the mil once you get it dialed in where you need it.:thumb:

Definitely look into that, unfortunately i do not have efi live directly available to me.

Changed the maf out to one from a friends duramax, still throws the engine light even after clearing the code
