Pinpoint Test Dm: Manifold Pressure Sensors: Introduction

WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 2020 Lincoln Navigator, 2020 Lincoln Nautilus, 2020 Lincoln MKZ, 2020 Lincoln Corsair, and 2020 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.

This pinpoint test is intended to diagnose the following:

manifold absolute pressure (MAP) sensor (9F479)
manifold absolute pressure (MAP)/charge air cooler temperature (CACT) sensor (9F479)
manifold absolute pressure (MAP)/intake air temperature 2 sensor (IAT2) sensor (9F479)
manifold absolute pressure and temperature (MAPT) sensor (9F479)
turbocharger boost pressure (TCBP) sensor (9F479)
turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor (9F479)
turbocharger inlet pressure and temperature (TCIPT) sensor (9F479)
harness circuits: MAP, TCBP, TCIP, SIGRTN, and VREF
PCM (12A650)
