INJECTION - IGNITION
9
Air pressure sensor
This sensor (1) is integrated in the ECU and indicates the atmospheric pressure.
This data is managed by the ECU and is used to correct the calibration.
NOTES
The information about the atmospheric pressure is displayed through the use of the Service
Walbro.
Coolant temperature sensor
The sensor (2) is mounted on the horizontal cylinder head coolant outlet union and measures the
coolant temperature. The electrical signal obtained is sent to the ECU and it is used to correct the
calibration, so as to ensure optimal ignition and fuel supply at all times. It is composed of a body
containing an NTC thermistor (the resistance of the thermistor decreases as the temperature
increases)
water temperature sensor removal
To remove the coolant temperature sensor remove the L.H. fairing and the battery support as
explained in this section.
Disconnect the wiring connector.
Unscrew the sensor (2) from the coolant manifold (3).
