Oil temperature sensor

See fig. 110.
For readings of the oil temperature, a sensor Q is fitted to the oil pump
housing. The sensor is an NTC resistor and identical with the two sensors
for cylinder head temperature.
The standard temperature should be between 90 and 110°C (194 - 230° F).
If max. temperature 140°C (284° F) is exceeded, check
— oil system
— temperature sensor
— monitoring instrument
— cable connection
— sensor cable
See Maintenance Manual type 912 Series (Line Maintenance) Chapter
05-50-00 para 2.8.
The sensor is grounded directly via the oil pump
housing.

Oil pressure sensor

See fig. 110, 111 and 112.
The sensor W for measuring of oil pressure is screwed into the oil pump
housing.
The standard oil pressure in the engine is between 1,5 - 5 bar (22 - 73 psi).
The sensor covers a range of 0 - 10 bar (0 - 145 psi).
CAUTION: The pressure range of the monitoring instrument must by
all means be adapted to the pressure range of the
sensor. Otherwise there will be wrong reading of the oil
pressure.

CAUTION: At replacement of a temperature
sensor, always let the engine cool
