Pinpoint Tests Dm: Manifold Pressure Sensors: Introduction

WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2021 Lincoln Navigator, 2021 Lincoln Nautilus, 2021 Lincoln Corsair, 2021 Lincoln Aviator, and 2021 Ford Transit-350 HD. 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)/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)
