Wondering if anyone can tell me what color wire goes to each terminal on MAF connecter. Looked on line and I get three different combinations. Just unwrapped the wires and it has a new connecter on it. I want to check if the way they did it is correct. Can't get it to run right and want to check before buying parts. Connecter is 1-6 and 1 is not used.

2006 altima 2.5l MAF sensor wiring diagram
Found the right diagram. Tested MAF with multi tester. Y/G 5.08 at startup (very cold out) 3.87 at idle after warm up. Red .01 W 1.2 Black .01 red 14.27. Looks like the 5.08 at startup and 3.87 after warm up is way too high. Bad MAF?
The MAF supply on an '06 is 12V, not 5V. Your wire ID's are:
2 - R/G - 12V Supply
3 - B - Ground (MAF)
4 - W - MAF Signal
5 - Y/G - Intake Air Temp Signal
6 - R - Ground (IAT)
Normal MAF signal at idle is 1.0~1.5V, yours is about nominal at 1.2V. I don't recall what the IAT should read, but the fact that Y/G moves when warm implies that it's working.
2 - R/G - 12V Supply
3 - B - Ground (MAF)
4 - W - MAF Signal
5 - Y/G - Intake Air Temp Signal
6 - R - Ground (IAT)
Normal MAF signal at idle is 1.0~1.5V, yours is about nominal at 1.2V. I don't recall what the IAT should read, but the fact that Y/G moves when warm implies that it's working.
You're most welcome. Yes, the MAF signal is generally in the 1.0~1.5V range at idle and yours is within the range. So if you have a MAF issue it will be a performance or calibration issue, not a flatlined sensor.
