Oil Level And Oil Temperature Sensor
The sensor is a combined oil level and oil temperature sensor. The function of the sensor is to provide the engine control module (ECM) with information about the level and temperature of the engine oil in the oil trough.
The sensor consists of:
- a terminal with three pins
- integrated electronics
- 2 capacitive gauge elements
- a PTC resistor.
The sensor is supplied with 5 V from the engine control module (ECM) and generates a pulse width modulation (PWM) signal to the engine control module (ECM).
The engine control module (ECM) can diagnose the sensor.
