Air Pressure Sensor; Coolant Temperature Sensor - Ducati SUPERBIKE 848 MY 2008 Manual

System components
Notes
The influence of the stepper motor air flow is present to approximately 30° throttle angle; no
correction is required for greater angles.
The opening of the stepper motor opening is controlled by 2 strategies:
Strategy 1) controlled solely by engine temperature (stepper motor opening/closing is determined by
engine temperature alone).
Strategy 2) controlled by engine temperature and status. This strategy is applied only in the engine
starting phase; the system determines a quantity of steps, to be added to those of the previous
strategy, which are immediately decreased to zero, in accordance with the number of engine cycles,
once the system has detected that the engine has started.

Air pressure sensor

This sensor is integrated in the instrument panel and indicates the atmospheric air pressure. This
information is sent to the ECU by a serial line (CAN line), and is used to correct the calibrations stored
in the Flash Eprom.
Notes
To test the operation of the injector, use the DDS tester and follow the instructions given in the
paragraph Guided diagnosis

Coolant temperature sensor

This sensor is mounted on the horizontal cylinder head coolant outlet union and measures the coolant
temperature. This information is sent to the ECU and used to correct the calibrations stored in the
Flash Eprom so as to ensure optimal ignition and fuel supply at all times. The same information is sent
to the instrument panel via the CAN line for the coolant temperature display. It is composed of a body
containing an NTC thermistor (the resistance of the thermistor decreases as the temperature
increases).
Notes
To test the operation of the coolant temperature sensor, use the DDS tester and follow the instructions
given in the paragraph
Removal of the coolant temperature sensor
To remove the coolant temperature sensor, first remove the LH side fairing (Sect. E 2,
side fairings) and the battery support (as explained in this section).
Disconnect the wiring connector.
Unscrew the sensor (1) from the coolant manifold (2) (Sect. P 1,
