Guys, I'm dealing with a P0101 code (MAF Sensor Performance) code that I can't seem to sort out. Truck is a stock '09 LMM. It will clear, but then goes on after the truck runs for a minute or two. It throws the code and also then immediately shows ENGINE POWER REDUCED on the dic. He's what I've tried:
I've swapped the MAF with another good known MAF from another '09 LMM we have here.
I've pinned out the connector for voltage with the truck at idle to ensure I am not dealing with a wiring issue and compared the values to another good known truck and am getting the same values, so I know wiring is good.
I've checked for leaks in the (all stock) intake tubing and everything looks good. Air filter looks fine and is stock.
What could possibly be going on here? Its driving me nuts. Can't get the code to clear. It will come back on without even driving the truck-- just running at idle makes it come on.
Please help if you have ideas. Thanks in advance guys.
