Hello,

I have included the information that you requested in the diagrams down below. I have also included a wiring diagram showing the Mass Air Flow sensor (MAF) for your vehicle. If needed we can also give you the same information for your vehicle's Intake Air Temperature sensor (IAT), as they work in concert to determine the temperature and the volume of air that is entering your vehicle's engine. Please go through these guides and let us know about the IAT, as well as how everything turns out with the MAF.

Thanks,
Alex
