PINPOINT TEST DC: Mass Airflow (MAF) Sensor: Introduction
WARNING: This page does not describe the selected car, but rather 28 other vehicles, including the 2014 Lincoln Navigator, 2014 Lincoln MKZ, 2014 Lincoln MKX, 2014 Lincoln MKT, and 2014 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- mass airflow (MAF) sensor (12B579)
- harness circuits: IAT, GND, MAF, MAFRTN, SIGRTN and VPWR
- powertrain control module (PCM) (12A650)
