B40 Oil sensor (oil level/temperature/quality)
Oil sensor position | The oil sensor (B40) is located at the rear of the oil pan at the engine. | ||
Oil sensor task | Detecting oil level, oil temperature and oil quality. | ||
Oil sensor design | The oil sensor consists of: Electronics with three-pin plug connection 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 and passed on to the engine control module. |
