Oil Level And Temperature Sensor
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 Instrument Cluster (IC) message center.
The oil level and temperature sensor sends a signal to the Powertrain Control Module (PCM). The signal contains the level of the engine 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.
The temperature function of the oil level and temperature sensor is not operational on the V8 5.0L S/C Petrol engine.
The oil level and temperature sensor sends an ultrasonic pulse vertically upward. The sensor 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 to determine the oil level. The oil level reading is transmitted in a Pulse Width Modulation (PWM) signal to the PCM.
