Manifold Absolute Pressure (MAP) sensor:
The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold vacuum. The MAP sensor signal voltage to the PCM varies from less than 2 volts at idle and high vacuum, to more than 4 volts with the key ON, the engine not running or at wide-open throttle. The MAP sensor is used to determine manifold pressure changes while the linear EGR flow test diagnostic is being run, to determine engine vacuum level for other diagnostics, and to determine the Barometric Pressure (BARO) .

If the PCM detects a voltage that is less than the possible range of the MAP sensor, DTC P0107 is set. A signal voltage more than the possible range of the sensor sets DTC P0108. An intermittent voltage sets DTC P1107 or DTC P1106 respectively.

On top of the engine, rear of the intake manifold.
