The Manifold Absolute Pressure (MAP) sensor allows the Powertrain Control Module (PCM) to calculate the load on the engine. The calculated engine load is used by the PCM in the calculation of fuel injection time.

The MAP sensor is installed in the air inlet of the supercharger. The sensor is secured with a single screw and sealed with an O-ring. A 3 pin electrical connector provides the interface with the engine wiring harness.

If the MAP sensor fails, the PCM adopts a default value of 1 bar (14.5 psi). With a failed MAP sensor, the engine will suffer from poor starting, rough running and poor driveability.
