Oil Level Monitoring

WARNING: This page is about a different variant/trim than selected.

Oil level monitoring is provided by an oil level and temperature sensor that measures the oil level in the oil pan. The oil level can be displayed in the message center of the Instrument Cluster (IC).

For additional information, refer to: INSTRUMENT CLUSTER

The oil level and temperature sensor supplies the PCM with a signal containing the level of the oil in the oil pan. The oil level and temperature sensor is secured to the bottom of the oil pan with three screws and sealed with a gasket.

The temperature function of the oil level and temperature sensor is not operational on the 3.0L V6 SC engine.

The oil level and temperature sensor sends an ultrasonic pulse vertically upward and measures the time taken for the pulse to be reflected back from the top surface of the oil. This time is compared with the time taken for an ultrasonic pulse to travel a reference distance within the oil level and temperature sensor to determine the oil level. The oil level reading is transmitted in a PWM signal to the PCM.
