Manifold Absolute Pressure (MAP) sensor and Barometric Pressure (BARO) sensor, checking: Notes

WARNING: This page is about a different variant/trim than selected.

The altitude sensor is located in the Diesel direct injection system control module. The manifold absolute pressure sensor is a separate component and is located in the pipe between the charge air cooler and intake manifold.

NOTE:

Only gold-plated contacts may be used to repair the terminals in the manifold absolute pressure sensor with intake manifold temperature sensor.
