Circuit description
The oil temperature and the oil level sensor is a com-
bined
sensor.
The oil level sensor, pin1, is fed a current
pulse of approx. 250mA during approx. 600ms and the
voltage output will be sampled three times during this
time. To obtain the oil level the oil temperature has to
be used as a reference due to that the oil level output
voltage will alter depending on the oil temperature.
