The Boost Air Pressure Sensor is used to monitor the pressure of the air in the intake system after the turbocharger. The sensor consists of a pressure sensitive diaphragm/amplifier sensor. Air pressure causes the sensors diaphragm to deflect and produce an electrical signal proportional to the pressure. The diaphragm deflection signal is amplified in the sensor.
The sensor signals are used to calculation fuel injection and is monitored by the Engine Control Module (ECM).
The engine control module (ECM) will set a diagnostic trouble code (DTC) and derate the engine to avoid engine damage if the sensor signal is not within predetermined limits, or the signal is not rational.
Conditions for diagnostic trouble code (DTC):
1) The sensor signal is not rational
Probable cause
1) Intake Manifold Pressure/Temperature Sensor
2) Wiring harness
