Manifold Absolute Pressure (MAP) Sensor
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.
The MAP sensor is located on the intake manifold and measures the intake manifold pressure. The PCM uses this information to determine the air charge and to provide the input for various engine control functions. The MAP sensor may be integrated with an intake air temperature (IAT) sensor.
