B.6.2.1.C
For a detailed description of the system, see the paragraph A.10.1.
An oil temperature sensor is mounted on the right rear of the oil sump. The data from the sensor
is sent to the injection control unit: do not remove or intercept the signal from this sensor for any
reason. If you need to add an oil temperature sensor read paragraph A.16.3. The engine lubricant
pressure is measured by a sensor placed on the upper left side of the crankcase under the injection
control unit.
