Oil Pressure Sensor - Ducati MONSTER 821 Workshop Manual

Oil pressure sensor

The oil pressure sensor (pressure switch) (1) is located on the front lower area.
To test the operation of the engine oil pressure sensor (1), proceed as follows.
Use the diagnosis instrument DDS 2 to check that oil pressure in the engine lubrication circuit complies with
the specified values.
If the engine oil pressure value is outside the specified range, check the lubrication circuit components and
service as necessary.
Switch on the instrument panel (ignition key turned to ON) without starting the engine, disconnect the
electrical terminal from the pressure sensor and connect it to ground:
- if the warning light does not illuminate, this means the sensor is defective and must be replaced;
- if the warning light illuminates, start the engine;
- if the warning light does not turn off, check the DDS 2 system by connecting to connector (A) located on
the rear subframe, LH side; to reach it, remove the seat.
