DORSODURO FACTORY ABS
Engine speed sensor P0336 - Synchronism lost
Error cause
•
Displayed if the signal is not as the control unit expects, for example due to voltage fluctu-
ations not correctly repeated.
Troubleshooting
•
Check that the flywheel teeth are clean and the sensor is adequately placed in its fitting: if
not OK, restore; if OK, replace the sensor.
Twistgrip position sensor
THROTTLE GRIP POSITION SENSOR
Function
The throttle grip is the part to which the throttle control cables arrive; its task is to translate the rider's
power request (Demand) into an electrical signal to be sent to the electronic control unit.
Operation / Operating principle
The two throttle cables (opening and closing) actuate on a scroll mounted on a shaft which is sent back
to its home position by a return spring. On the shaft covers there are 2 double track potentiometers (4
control tracks) by means of which the torque demand is read (and checked). The 4 potentiometers are
tinned and magnetically controlled (contactless); they cannot be overhauled nor replaced
Level in electrical circuit diagram:Throttle grip position sensor.
Location:
•
on the vehicle: under the fuel tank
•
connector: direct to the Marelli control unit
Electrical characteristics:
•
Not detected by a multimeter as they are contactless: read voltage on the 4 tracks through
Navigator.
CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
