Oil sensor position		GF18.40-P-4111-01M
Oil sensor task	Detect oil level, oil temperature and oil quality.
Oil sensor design	The oil sensor consists of: Electronics with 3-pin connector Capacitive measuring element (capacitors) Temperature sensor.
Oil sensor function	Oil level and oil quality are detected on the basis of the capacitance of the engine oil (dielectric). The oil temperature is detected by the temperature sensor. All the signals are processed in the electronics to form a PWM signal.	GF18.40-P-4111-02M
