Barometric pressure sensor
Filtered engine oil pressure sensor
Filtered fuel pressure sensor
Left turbocharger inlet pressure sensor
Right turbocharger inlet pressure sensor
Turbocharger outlet pressure sensor
Unfiltered engine oil pressure sensor
Unfiltered fuel pressure sensor
Crankcase pressure sensorThe analog sensor supply voltage is routed to terminal 1 of each sensor connector. The sensor return is routed to terminal 2 of each sensor connector. The sensor signal is routed to terminal 3 of each sensor connector. The ECM provides short circuit protection for the internal power supply. A short circuit to the battery will not damage the internal power supply.The ECM performs an automatic calibration of these sensors whenever the ECM is powered and the engine is off for at least five seconds. During an automatic calibration, the ECM calibrates pressure sensors to the value of the atmospheric pressure sensor and against an acceptable offset pressure range.The ECM continuously outputs a pull-up voltage on the input terminal from an analog sensor. The ECM uses this pull-up voltage in order to detect an open or a short in the signal circuit. When the ECM detects high signal current on the sensor, the ECM will generate an open circuit diagnostic code -3 for that sensor. When the ECM does not detect pull-up voltage on the signal circuit, the ECM will generate a short circuit diagnostic code -4 for that sensor. Pull-up voltage at the sensor connector indicates that the wires from the sensor connector to the ECM are not open or shorted to ground.
