100-13     Engine Oil Pressure Sensor : Calibration Required     The code is logged.
During a manual calibration, the pressure offset value is set to
0 kPa (0 psi).
During an automatic calibration, the pressure offset value is set to the previous calibration value.    
101-13     Crankcase Air Pressure Sensor : Calibration Required     The code is logged.
During a manual calibration, the pressure offset value is set to
0 kPa (0 psi).
During an automatic calibration, the pressure offset value is set to the previous calibration value.    
274-13     Atmospheric Pressure Sensor : Calibration Required     The code is logged.
During a manual calibration, the pressure offset value is set to
0 kPa (0 psi).
During an automatic calibration, the pressure offset value is set to the previous calibration value.    
1785-13     Intake Manifold Pressure Sensor : Calibration Required     The code is logged.
During a manual calibration, the pressure offset value is set to
0 kPa (0 psi).
During an automatic calibration, the pressure offset value is set to the previous calibration value.    
3385-13     EGR Intake Pressure Sensor : Calibration Required     The code is logged.
During a manual calibration, the pressure offset value is set to
0 kPa (0 psi).
During an automatic calibration, the pressure offset value is set to the previous calibration value.    
3387-13     EGR Differential Pressure Sensor : Calibration Required     The code is logged.
During a manual calibration, the pressure offset value is set to
0 kPa (0 psi).
During an automatic calibration, the pressure offset value is set to the previous calibration value.    The Electronic Control Module (ECM) checks the signals from certain pressure sensors when the keyswitch is turned to the ON position. The keyswitch must remain in the ON position for 30 seconds in order for the ECM to check the signals from the sensors.The signal from the atmospheric pressure sensor, crankcase pressure sensor, and NRS differential pressure sensor are compared to a value stored in the ECM. The appropriate fault code is active if either signal is outside of the specified range.The ECM compares the signal from the intake manifold pressure sensor with the signal from the atmospheric pressure sensor.The sensor signal must be within the specified range of the signal from the reference pressure sensor. If a sensor signal is out of the range, the corresponding fault code becomes active.

Use Caterpillar Electronic Technician (ET) to check for calibration codes that are active or logged.If the 274-13 Atmospheric Pressure Sensor : Calibration Required is active, perform the following procedure on the atmospheric pressure sensor prior to troubleshooting calibration codes for the other sensors. Perform the following procedure in order to troubleshoot active calibration codes:
Inspect the connector of the suspect sensor. Verify that no moisture or corrosion is present in the connector assembly. Thoroughly inspect the connector seal for damage. Reconnect the connector.
Monitor the status parameter for the suspect sensor on Cat ET. Wiggle the wiring at the suspect sensor connector. While you wiggle the wiring, check that the value of the status parameter remains steady during the test.If the value of the status parameter does not remain steady during the test, perform the necessary repairs to the wiring and/or the sensor connector.Verify that the problem is resolved.If the value of the status parameter remains steady during the test, use Cat ET to check for an active calibration code. If the code is active, replace the suspect sensor.Verify that the problem is resolved.
Inspect the connector of the reference sensor. Verify that no moisture or corrosion is present in the connector assembly. Thoroughly inspect the connector seal for damage. Reconnect the connector.
Monitor the status parameter for the reference sensor on Cat ET. Wiggle the wiring at the reference sensor connector. While you wiggle the wiring, check that the value of the status parameter remains steady during the test.If the value of the status parameter does not remain steady during the test, perform the necessary repairs to the wiring and/or the sensor connector.Verify that the problem is resolved.If the value of the status parameter remains steady during the test, use Cat ET to check for an active calibration code. If the code is active, replace the suspect sensor.Verify that the problem is resolved.
