Sensor, Oil Temperature: Description: Description
WARNING: This page is about a different car, the 2013 RAM 2500 HD and 2012 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The oil temperature sensor uses the following two 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 side of the engine block.
