Description: Exhaust Gas Temperature Sensor Bank 1 Sensor 1
Troubleshooting:
Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A137:42 is more than 4.84 V
2) Ignition key in ON position
Observable symptoms
1) Regeneration not possible
Probable cause
1) Wiring harness between component connector and electronic control unit (ECU) connector
2) Open circuit, Signal wire
3) Open circuit, Ground wire
4) Pre-catalyst, Exhaust Gas Temperature (EGT) Sensor

Description: Reductant Return No Flow Detected
Troubleshooting:
The aftertreatment control module (ACM) uses the aftertreatment diesel exhaust fluid (DEF)
dosing pressure sensor value to adjust and maintain DEF pressure at the DEF dosing valve by
controlling DEF pump speed. If the pressure decreases below expected value when the pump
is in initial pressure build-up mode or if the pressure increases above expected value when
pump is in idle speed mode, the ACM considers DEF pressure outside of normal operating
range and indicates a malfunction in a DEF dosing pressure sensor.
Conditions for diagnostic trouble code (DTC):
1) ACM_ Urea Pressure above 500 kPa
Observable symptoms
1) Aftertreatment DEF Pump Bleed Orifice
Probable cause
1) Restricted orifice in the aftertreatment fuel manifold
2) Damaged hoses and/or connections
3) Aftertreatment Diesel Exhaust Fluid (DEF) Pump

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A137:7 is above normal value
Observable symptoms
1) No aftertreatment diesel exhaust fluid (DEF) dosage
Probable cause
1) Short circuit to voltage supply, Control wire (-)
2) Short circuit to 5V, Control wire (-)
3) Wiring harness

Description: Crankshaft Position – Camshaft Position Correlation
Troubleshooting:
The camshaft position (CMP) sensor is an inductive device. As the camshaft turns, the tip of
the CMP sensor senses the teeth of the tone wheel fastened to the camshaft vibration damper.
The CMP sensor sends a series of voltage pulses to the Engine Control Module (ECM). The
frequency of the pulses is translated into engine speed (RPM) and position by the ECM. The
ECM uses this information along with the information from Crankshaft Position (CKP) sensor to
synchronize fuel injection.
Conditions for diagnostic trouble code (DTC):
1) The camshaft position sensor (CMP) signal has incorrect timing compared to the crankshaft
position sensor (CKP) signal
Observable symptoms
1) High fuel consumption
Probable cause
1) Engine geartrain
Detailed information
1) The camshaft geartrain is incorrectly timed
