The Manifold Absolute Pressure and Temperature (MAPT) sensor allows the Powertrain Control Module (PCM) to calculate the charge air density and temperature. The MAPT sensor is located immediately before the air enters the cylinders. This is used to adjust the ignition timing relative to the boost pressure and to monitor the performance of the charge air coolers.

The MAPT sensor is located in the rear of the left intake manifold. The sensor is secured with a single screw and sealed with an o-ring. A 4-pin electrical connector provides the interface with the engine wiring harness.

If the MAPT sensor fails, the engine will suffer from poor starting, rough running and poor drive ability.
