Oil Temperature Sensor
WARNING: This page is about a different car, the 2023 Jeep Grand Wagoneer. However, it is still accessible from the selected car via links, so may be relevant.
DESCRIPTION
Oil Temperature Sensor
The oil temperature sensor (1) uses the following two Powertrain Control Module (PCM) circuits:
- Signal circuit to the PCM
- Ground circuit from the PCM
The oil temperature sensor is a Negative Thermal Coefficient sensor. The resistance of the sensor changes as oil temperature changes. This results in different output voltages back to the PCM.
The oil temperature sensor is located on the right front of the engine.
