Electronic Viscous Fan: The Electronic Fan Drive contains a solenoid that controls the flow of fluid between reservoirs in the fan drive housing and cover. The Engine Control Module (ECM) provides a (PWM) Pulse Width Modulation signal to the solenoid and controls solenoid operation to optimize fan speed, based on coolant temperature, intake air temperature and A/C load. Conditions for diagnostic trouble code (DTC):1) The voltage at pin A14.EA:26 is below normal value Observable symptoms1) The fan will rotate at full speed at low engine speed2) At high engine speeds, the fan will either be disengaged or run at low...

The oil thermostat is located in the oil filter housing and controls the engine oil temperature by controlling if the oil is sent through the oil cooler or not. The Engine Control Module (ECM) monitors that the thermostat is working as expected by comparing the Engine Oil Pressure (EOP) Sensor value to a calculated oil temperature. Conditions for diagnostic trouble code (DTC):1) The voltage at pin A14.EB:53 is between 33?% and 67?% of the battery voltage Diagnostic operating conditions1) Ignition key in ON position Observable symptoms1) Increased fuel consumption2) Low oil temperature Probable cause1) Open circuit on common supply wire...
