PINPOINT TEST DN: Pressure and Temperature Sensors: Introduction
WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2012 Lincoln Navigator L, 2012 Lincoln Navigator, 2012 Lincoln MKZ, 2012 Lincoln MKX, and 2012 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
This pinpoint test is intended to diagnose the following:
- turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor (9F479)
- manifold absolute pressure (MAP)/intake air temperature 2 (IAT2) sensor (9F479)
- turbocharger intake pressure and temperature (TCIPT) sensor (9F479)
- harness circuits: CACT, IAT, IAT2, MAP, TCBP, TCIP, SIGRTN and VREF
- powertrain control module (PCM) (12A650)
