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...

The Turbo Speed Sensor is an inductive sensor. When the engine is running, the turbocharger shaft rotates past the Turbo Speed Sensor tip and a pulsed voltage signal is generated. The Engine Control Module (ECM) monitors the frequency of the signal generated by the Turbo Speed Sensor to calculate the turbo speed.The turbo speed signal is used to calculate fuel injection. Conditions for diagnostic trouble code (DTC):1) The turbocharger speed is more than the value needed for the observed intake manifold pressure Observable symptoms1) Intermittent power loss Probable cause1) Engine wiring harness2) Incorrectly installed sensor3) Turbo Speed Sensor4) Charge air...
