Description: Diesel Intake Air Flow Position Sensor
Troubleshooting:
Conditions for diagnostic trouble code (DTC):
1) The voltage is more than 4.7 V
Diagnostic operating conditions
1) Ignition key in ON position
Probable cause
1) Short circuit to voltage supply, control wire
2) Throttle Position Sensor

Description: Cylinder 1 Misfire Detected
Troubleshooting:
Fuel Injector operation is controlled by the Engine Control Module (ECM). The ECM provides a
common supply voltage to injectors 1,2,3 (Bank 1) and there are individual output transistor
drivers inside the ECM to control each individual injector’s ground circuits. There are two
solenoid circuits within the injector; a Needle Control Valve and a Spill Valve. Although they are
separate circuits, the same fault code is used to identify a fault in the Needle Control Valve
circuit and/or the Spill Valve circuit.
Conditions for diagnostic trouble code (DTC):
1) Injector (INJ) activated
2) Cylinder balancing data too high
Observable symptoms
1) Low Power
2) Engine idles unevenly
Probable cause
1) Injector 1
2) Worn injector
3) Faulty timing
4) Injector Clogged
5) Low compression

Description: Camshaft Position Sensor “A” Bank 1 or Single Sensor
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) Engine Control module (ECM) detects extra pulses on the crankshaft position (CKP) signal
Observable symptoms
1) Difficult to start at next start despite that no diagnostic trouble code (DTC) is set when the
engine is running
2) Loss of power
Probable cause
1) Camshaft Position (CMP) Sensor
2) Wiring harness
3) Tooth wheel
Detailed information
1) Electrical interference in the crankshaft position (CKP) sensor signal
2) Incorrectly installed sensor (incorrect distance to tooth wheel)
3) Poor insulation
