Mass Air Flow/Intake Air Temperature (MAF/IAT) Sensor Connector Pin Reference Chart: Notes
WARNING: This page is about a different car, the 2009 Ford RV Cutaway, 2009 Ford Econoline, 2009 Ford E450 Super Duty, and 2009 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- MAF sensor
- harness circuits: MAF SIG, MAF RTN, vehicle power (VPWR), and power ground (PWRGND)
- Powertrain control module (PCM) (12A650)
