Description: Crankcase Pressure Too High
Troubleshooting:
The Crankcase Pressure Sensor is used to detect crankcase pressure system failures. The
sensor consists of a pressure sensitive diaphragm and amplifier. Crankcase pressure causes
the sensor’s diaphragm to deflect and produce an electrical signal proportional to the pressure.
The diaphragm deflection signal is amplified in the sensor.
The engine control module (ECM) will set a diagnostic trouble code (DTC) if the sensor signal
is not within predetermined limits. The ECM can also disable the engine brake, derate or shut
down the engine to avoid engine damage.
The sensor’s signal is monitored by the Engine Control Module (ECM).
Conditions for diagnostic trouble code (DTC):
1) Irrational pressure
Observable symptoms
1) Engine shutdown
2) Engine brake disabled
3) Low Power
4) Limited engine speed
Probable cause
1) High engine oil level
2) Excessive wear or damage to cylinder liners, piston, piston rings or turbocharger internal
seals
3) Restricted crankcase ventilation
4) The following connectors may have been switched: B54: Crankcase pressure sensor, B118:
Engine oil pressure (EOP) sensor
Detailed information
1) The alarm sounds if the pressure is more than 5 kPa (0.73 psi)

Description: Idle Control System – Fuel Quantity Higher Than Expected
Troubleshooting:
The Engine Control Module (ECM) monitors the crankshaft angular acceleration using the
flywheel sensor. The ECM monitors the camshaft position sensor to determine the engine’s
position. The ECM calculates the average value of crankshaft angular acceleration for all six
cylinders and compares the value to each individual cylinder’s angular acceleration. If a
cylinder’s acceleration value is outside a specified range the ECM interprets this as a misfiring
cylinder. The crankshaft average angular acceleration value is used by the ECM to determine
cylinder balancing and idle speed.
Conditions for diagnostic trouble code (DTC):
1) Calculated fuel consumption, Above normal
Observable symptoms
1) High fuel consumption
Probable cause
1) Power Take Off (PTO) installed without updating parameters and/or software
2) Parameter code, unit injector
3) Fuel
4) Injector

Description: Engine Oil Pressure Out of Range
Troubleshooting:
The Engine Oil Pressure Sensor is used to detect engine lubrication system failures. The
sensor consists of a pressure sensitive diaphragm and amplifier. Engine oil pressure causes
the sensor’s diaphragm to deflect and produce an electrical signal proportional to the pressure.
The diaphragm deflection signal is amplified in the sensor.
The sensor’s signal is monitored by the Engine Control Module (ECM).
The engine control module (ECM) will set a diagnostic trouble code (DTC) and derate the
engine to avoid engine damage if the sensor signal is not within predetermined limits, or the
signal is not rational.
Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A14.EB:11 is less than 0.3 V
Observable symptoms
1) The engine oil pressure (EOP) gauge shows 0 when the engine is running
2) Loss of power
Probable cause
1) Open circuit, Signal wire
2) Open circuit, Supply wire
3) Short circuit to ground, Signal wire
4) Engine oil pressure (EOP) sensor

Description: Park Brake Sensor/Switch Circuit Low
Troubleshooting:
The VECU reads the status of the parking brake switch; this information is transmitted via the
J1939 data link in order for the Engine Control Module (ECM) to read the parking brake status.
If vehicle speed is detected when the switch is closed or circuit shorted to ground this
diagnostic code (DTC) will be set after two ignition cycles.
Conditions for diagnostic trouble code (DTC):
1) Short circuit to ground in the component or wiring
Observable symptoms
1) Brake lights are lit without obvious reason
2) Vehicle speed is not zero
Probable cause
1) Damaged component
2) Damaged wiring harness
3) Damaged connector
4) Vehicle Control Unit (VECU)
