There is not a trouble shooting guide for the Blow through turbo MAFs included in our turbo tuning packages, so I thought I would post the voltage specs to look for if you are trouble shooting your car.
Pin 2- GREY YELLOW
-key in the on position engine off - 0.01v
-engine idling - 0.7v approx (will vary based on idle speed)
If these voltages are within spec the sensor is likely not causing your problem.
Pin 3- RED WHITE
-This is your 12v power supply. If you do not have 12v with your key in the on position then you most likely have a problem with your wiring harness
