Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

• Perform the glow plug learning procedure
• Faulty glow plug 4

Technical Notes

If a glow plug has been replaced, perform a glow plug learning procedure using a scan tool.⚠

Description

The glow plug control module has not learned the glow plug offset values. If a glow plug has been replaced and glow plug learning has not been performed, or if the glow plug control module encounters an EEPROM error or data corruption, this diagnostic trouble code (DTC) will be set. The DTC will be set if the hot resistance of the glow plugs is outside a predetermined threshold.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Engine light on (or engine maintenance warning light soon)

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

• Perform the glow plug learning procedure
• Faulty glow plug 5
• Glow plug 5 circuit is open or shorted
• Poor electrical connection in glow plug 5 circuit

Possible Symptoms

• Engine light on (or engine maintenance warning light soon)

Possible Causes

NOTE: The listed causes may not be a complete list of all potential problems and there may be other causes.

• Faulty camshaft position sensor
• Camshaft position sensor harness is open or shorted
• Poor electrical connection in camshaft position sensor circuit
• Faulty starter
• Starting system circuit
• Dead (weak) battery

Description

The camshaft position sensor is an electronic device used in an engine to record the rate at which the camshaft spins. This information is used by the Engine Control Module (ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of the camshaft (intake) to identify a particular cylinder. The camshaft position sensor detects the position of the piston. The sensor system consists of a rotating part, typically a disk, as well as a static part, the sensor itself.
When the engine is rotating, the high and low parts of the teeth cause a change in the gap with the sensor. The changing gap results in a change in the magnetic field near the sensor. The change in the magnetic field causes a change in the sensor voltage.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various commands for engine components instead, using the timing of cylinder identification signals.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
