Refer to ELECTRONIC ENGINE CONTROLS SYSTEM - 3.5L GTDI for schematic and connector information.
Normal Operation and Fault Conditions
This transfer case fluid temperature sensor is located in the PTU. It is a temperature-sensitive device called a thermistor. The resistance value of the sensor varies with temperature change. The PCM monitors the voltage across the transfer case fluid temperature sensor to determine the temperature of the PTU fluid temperature.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P182B | Transfer Case Fluid Temperature Sensor Circuit Range/Performance | The PCM is reporting the transfer case fluid temperature sensor has an in-range fault. |
| P182C | Transfer Case Fluid Temperature Sensor Circuit Low | The PCM is reporting the transfer case fluid temperature sensor voltage has failed low, (low voltage, high temperature). |
| P182D | Transfer Case Fluid Temperature Sensor Circuit High | The PCM is reporting the transfer case fluid temperature sensor has failed high, (high voltage, low temperature). |
