Oil Level Monitoring
WARNING: This page is about a different variant/trim than selected.
The oil level and temperature sensor supplies the Powertrain Control Module (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 3 screws and sealed with a gasket.
NOTE:
The temperature function of the oil level and temperature sensor is not operational on the V6 3.0L S/C engine.
The oil level and temperature sensor sends an ultrasonic pulse up through the engine oil and measures the time taken for the pulse to be reflected back from the surface. The time taken is compared to a reference distance within the oil level and temperature sensor to determine the oil level. The oil level reading is transmitted using a Pulse Width Modulation (PWM) signal to the PCM.
