in conjunction with the Atmospheric Pressure Sensor to determine if the engine air filter is plugged. The sensor indicates if the right turbocharger compressor inlet has a restriction. The sensor output is a DC voltage between 0.2 VDC and 4.8 VDC that varies with right turbocharger compressor inlet pressure. The operating range of the sensor is 0.0 kPa to 111 kPa (0.0 psi to 16 psi). The ECM calibrates the sensor within the first five seconds after power is applied to the ECM. The ECM checks the sensor value against an acceptable pressure range. If the pressure value is not in this range the previous calibration will be used. A manual calibration of the sensor should be done if the sensor or the ECM has been replaced. Refer to the calibration procedure Troubleshooting, "Anolog Sensor - Calibrate".Turbocharger Compressor Outlet Pressure Sensor - The
