PINPOINT TEST DM: Manifold Pressure Sensors: Introduction

WARNING: This page does not describe the selected car, but rather 34 other vehicles, including the 2019 Lincoln Navigator, 2019 Lincoln Nautilus, 2019 Lincoln MKZ, 2019 Lincoln MKT, and 2019 Lincoln MKC. 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)
