I Got maf code read out from autozone. It said Cold air temp sensor is bad. I wanted to check the sensor with my osilliscope. I wanted to know if any one know with two wires are would hook up. I don't have the schematic of MAF. Traditionally, there are two wire for the maf, one wire for the intake air temp sensor, One power , and One ground.

there are five wire

black with white stripe- ????
red with black stripe - power wire
Brown - Ground

Can someone tell me which is Intake temp sensor ?

Have you installed a CAI? If so, start by cleaning the MAF of filter oil.

If there is a intake temp sensor in the 2008 cadi is separate from MAF, where would it be? GM is known for combining the air flow and intake temp sensor into one?

I think I got it. I looked a old color wire for maf and IAT sensor.

Yellow, Black/White stripe, red is maf

purple, tan would be IAT these 02 gm models

I think the red/black stripe and tan is the IAT

What do you guys think?
