Oil Level and Temperature Sensor
WARNING: This page is about a different car, the 2011 Jaguar XKR175, 2011 Jaguar XKR, and 2010 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
The oil level and temperature sensor supplies the ECM with a signal containing the level and temperature of the oil in the sump pan. The oil level and temperature sensor is secured to the bottom of the sump pan with three screws and sealed with a gasket.
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 combined with the oil temperature reading and transmitted in a PWM signal to the ECM.
