Barometric pressure sensor (Primary ECM)
Filtered engine oil pressure sensor (Primary & Secondary ECM)
Transmission oil pressure sensor (Primary & Secondary ECM)
Filtered fuel pressure sensor (Primary & Secondary ECM)
Left turbocharger inlet pressure sensor (Primary ECM)
Right turbocharger inlet pressure sensor (Primary ECM)
Turbocharger outlet pressure sensor (Primary & Secondary ECM)
Unfiltered engine oil pressure sensor (Primary & Secondary ECM)
Unfiltered fuel pressure sensor (Primary ECM)
Crankcase pressure sensor (Primary ECM)
Jacket water coolant pressure sensor (Primary & Secondary ECM)Background InformationThe 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 creates a pull-up voltage on the signal wire for each sensor. The ECM uses this pull-up voltage in order to detect a problem in the signal circuit. When the ECM detects voltage that is above a threshold on the signal wire, the ECM activates a high voltage -3 diagnostic code. When the ECM detects voltage that is below a threshold on the signal wire, the ECM activates a low voltage -4 diagnostic code.Note: There may be a delay of 30 seconds in order for Caterpillar Electronic Technician (ET) to display an active diagnostic code. When you check for a diagnostic code, be sure to wait at least 30 seconds.The following components can cause these codes:
Electrical connector or wiring
Sensor
ECMThe most likely cause of a code is a problem with an electrical connector or wiring. The least likely cause of a code is the ECM.
