Engine oil pressure sensor
Atmospheric pressure sensor
Turbocharger outlet pressure sensor
Injection actuation pressure sensorThe 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.Use this procedure to troubleshoot any suspect problems with the following temperature sensors:
Engine oil temperature sensor
Fuel temperature sensor
