The combination turbocharger compressor intake pressure/temperature sensor is used to measure ambient air pressure.The pressure measuring portion of the sensor responds to pressure changes in the atmospheric pressure, which occur based on elevation at which the engine is presently operating. The turbocharger compressor intake pressure sensor has a 5V supply circuit, a pressure sensor signal voltage, and a return circuit.The ECM will detect a low signal voltage when the vehicle is operating at high altitudes. The ECM will detect a high signal voltage when the vehicle is operating at sea level altitudes.
