cated by the diagnosis instrument: if the voltage does not vary, there is a short circuit in the
cable wiring; replace the throttle grip sensor if the voltage drops to zero.
•
if the circuit is open, shorted to negative: check the throttle grip sensor connector and the
Marelli control unit connector. If not OK, restore. If OK, check circuit continuity between the
two cable terminals. If not OK, restore; if OK, check the cable ground insulation (from the
throttle grip sensor connector or the control unit connector): if the cable is not ground insu-
lated, restore the wiring. If it is ground insulated, and with the switch key set to ON, check
that there is power supply for the potentiometer PIN D and that PIN F is connected to ground.
If both are correct, replace the throttle grip sensor; if not, check the continuity of the cable
that is not functioning properly: if there is continuity, replace the control unit; if not, restore
the wiring
DIAGNOSIS INSTRUMENT: LOGIC ERRORS
Blue lower connector throttle grip position (tracks A-B) P0154
•
incongruent signal
Error cause
•
Two illogical voltage signals have been detected at PIN 13 and 39 of the ENGINE connector
(tracks A-B)
Troubleshooting
•
Check the parameters of the blue lower connector Throttle Grip Position Sensor - tracks A
and B: if one of the two values clearly deviates from 600-1400 mV, it means that this po-
tentiometer is defective. Check the throttle grip sensor connector and the control unit
connector: if not OK, restore. If OK, check that cable resistance between the throttle grip
sensor connector and the control unit is a few tenths of Ohm: if this is not the case, restore
wiring. If the value is correct, replace the complete throttle grip sensor
White upper connector throttle grip position (tracks C-D) P0155
•
incongruent signal
Error cause
•
Two illogical voltage signals have been detected at PIN 23 and 11 of the ENGINE connector
(tracks A-B)
Troubleshooting
•
Check the parameters of the white upper connector Throttle Grip Position Sensor - tracks
C and D: if one of the two values clearly deviates from 600-1400 mV, it means that this
potentiometer is defective. Check the throttle grip sensor connector and the control unit
connector: if not OK, restore. If OK, check that cable resistance between the throttle grip
sensor connector and the control unit is a few tenths of Ohm: if this is not the case, restore
wiring. If the value is correct, replace the complete throttle grip sensor
