The Manifold Absolute Pressure and Temperature (MAPT) sensor allows the Powertrain Control Module (PCM) to calculate the charge air density immediately before it 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 installed in the left charge air cooler outlet. 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.

With a failed MAPT sensor, the engine will suffer from poor starting, rough running and poor driveability.
