Hey guys, car has been throwing a code for the MAF. So, I bought a new one...genuine GM part...and i am still getting the same code. Is there anyway to test the MAF to see if it is a faulty part? Any help or recomendations are greatly appreciated.

 

check your wiring harness.. you probably just have a loose connection. I had the same problem with my car at one time and had to rebuild the connector.

 

What was the exact code you got? The 97's seem to be prone to the code for the MAF "circuit" and the problem is often a break in the pink wire that supplies +12V to the sensor. Pull the connector off the sensor, key on, don't start engine, and see if you have +12V on the pink wire, and a good ground on the black wire.
