Code P0675 Chrysler Description

The glow plug system is used to assist in providing the heat required to begin combustion during cold engine temperatures. The glow plugs are heated before and during cranking, as well as initial engine operation. The Engine Control Module (ECM) controls the glow plug ON times by monitoring coolant temperature and glow plug voltage. The glow plug system has individual glow plug supply circuits between the controller and the glow plugs. If the feedback voltage from the controller to the ECM is not within range, the ECM sets the OBDII code. The Diagnostic Trouble Code (DTC) will set if the Engine Control Module has detected a fault in the cylinder #5 glow plug circuit.
