13.5.3) Oil pressure sensor
See Pic. 194, 195 and 196.
The sensor W for oil pressure observation
is screwed into oil pump housing.
The range of the sensor is from 0 ÷ 10 bar.
This range is clearly indicated on the hexa-
gon E of sensor.
■ ATTENTION: It is absolutely necessary that
the pressure range of the pressure gauge corresponds with
the pressure range of the pressure sensor.
Non-correspondence would result in false oil pressure indication-check.
— lubrication system
— oil pressure sensor
— pressure gauge
— wiring connections
— sensor cable
◆ NOTE: Grounding connection of the sensor direct via the oil pump
housing.
For sensor resistance see graph above of sensor resistance over pressure.
Compare pressure gauge with a calibrated instrument.
■ ATTENTION: The graph resistance over pressure has been determined,
and is effective at the following conditions only.
ambient temperature: 20 °C
voltage: 12 V
deviation: max ± 5%
After removal of oil pressure sensor clean the thread. Secure new sensor with
LOCTITE 221 and tighten to 15 Nm (133 in.lb).
