Sensor, Oil Temperature: Description

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 (NTC) 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.
