Maf

Can anyone give me step by step info on checking the MAF.I 'm getting codep0101

Go to auto parts store and by a spray can of MAF sensor cleaner. Clean it and see if the code goes away. Follow the directions to the letter.

Which when translated means DON'T TOUCH THE WIRES!!!

wierd i just got this code last night but mine was for diff reasons :P

yeah for sure be careful on how close you spray it also those wires are very sensetive

DTC P0101

P0101 is almost always a wiring problem. MAF's are pretty robust these days. I'm making the assumption you're not F/I because that would make a huge difference (right mean05?)...

Its an 2003 Tahoe w/5.3 flex. when u say wiring problem - what specifically are u referring to?

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

SERVICE VME
This message applies to all 1999 through 2004 Chevrolet, GMC, Olds, Buick and Cadillac pick-ups and utilities that are equipped with either the 4.8 liter, 5.3 liter or 6.0 liter Gen 3 V-8 engines. Recent warranty analysis indicates that both the MAF, or mass airflow sensor, and the MAP, or manifold absolute pressure sensor, are being replaced for a MAF sensor code P0101. The cause may actually be a MAP sensor failure causing the MAF sensor code. One of the MAP sensor’s primary functions is the calculation of the speed density formula, which is compared to the MAF sensor reading. Should the MAP sensor fail, the PCM may interpret this as a MAF sensor concern and set a P0101 code. If diagnostics are followed thoroughly the technician may find a MAP sensor failure causing this condition. In conclusion, when a MAF sensor code of P0101 is found the technician needs to verify the proper operation of the MAP sensor before concluding that the MAF sensor requires replacement.

Aren't all emissions related components covered under emission warrantee for 100,000 miles?

thx. any idea where the map sensor is? I'm at 136,000 so that warranty wouldn't apply.
