Charge Air Pressure Sensor - G31- / Intake Air Temperature Sensor - G42-, Checking: Function

the Charge Air Pressure Sensor -G31- / Intake Air Temperature Sensor -G42- is located in the inlet to the intake manifold. the Engine Control Module -J623- uses the sensor's signal to regulate the charge air pressure. the re 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.
