Oil Temperature Sensor
WARNING: This page is about a different car, the 2024 Jeep Grand Cherokee L. However, it is still accessible from the selected car via links, so may be relevant.
DESCRIPTION
| 1 - Oil Temperature Sensor |
The oil temperature sensor uses the following two circuits:
- Signal circuit to the Powertrain Control Module (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 behind the generator.
