Manifold Absolute Pressure And Temperature Sensor
WARNING: This page is about a different variant/trim than selected.
The MAPT allows the PCM to calculate the charge air density and temperature. The MAPT 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 is located in the rear of the left intake manifold. The sensor is installed 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 fails, the engine suffers from poor starting, rough running and poor driveability.
