Oil Level Sensor
The function of the oil level sensor is to provide the engine control module (ECM) with information regarding the level of engine oil in the oil sump.
The sensor consists of:
- a terminal with three pins
- integrated electronics
- 2 capacitive gauge elements
- a PTC resistor.
The oil level sensor is supplied with 5 V by the engine control module (ECM). The oil level sensor generates a pulse width modulated (PWM) signal for the engine control module (ECM).
The oil level sensor can be diagnosed by the engine control module (ECM).
The pulse-width modulated (PWM) signal from the oil level sensor can be read using parameter readout.
