OIL TEMPERATURE SENSOR
DESCRIPTION
Oil level, oil temperature and oil quality are
detected by means of an oil sensor located in the oil
pan. The sensor which operates on the capacitance
principle features an integrated electronic circuit
which analyzes the three signals. the signals are con-
stantly relayed to the ECM and over the CAN bus to
the instrument cluster by means of PWM signal.
OPERATION
Oil quality is detected for indicating the need-
based oil change interval. The oil quality is detected
on the basis of the capacitance of the engine oil
(dielectrics, does not conduct electricity), this being
as much as six times greater in case of poor quality.

Oil level and oil quality are separate of each other.
The information is first of all compensated in the
ECM before being transmitted over the CAN bus.
Faults at the oil sensor are detected by the ECM
and entered into fault memory. The voltage for the
oil sensor (approx.5V) is supplied by the ECM.
