Charge Air Pressure Sensor - G31-, Checking: General Description

The Charge Air Pressure Sensor -G31- is located in the inlet to the intake manifold. The Engine Control Module -J623- uses the sensor's signal to regulate the turbo boost. There is no substitute function in the event of signal failure. Charge air pressure regulation is shut off, leading to a significant reduction in engine output.
