Oil Temperature Gauge: Description and Operation
Oil Level Sensor (2004-, Certain Markets And Models Only)
The oil level sensor provides the engine control module (ECM) with information about the quality and temperature of the engine oil and the oil level in
the oil trough. Which of these functions is used by the sensor varies between different car models.
All three functions are combined in one unit with a sensor section and an electronics section. There are no moving parts in the sensor.
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 PWM signal for the engine control
module (ECM). Also see Function.
The engine control module (ECM) can diagnose the functions of the oil level sensor. Also see Oil level sensor, diagnostics.
The oil level signal can be read out in VADIS parameter read out.
