BEFORE CARRYING OUT ANY TROUBLESHOOTING, CAREFULLY READ THE GENERAL TROU-
BLESHOOTING CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGINNING OF THE CHECK
AND CONTROL SECTION IN THE ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTICS INSTRUMENT: ELECTRICAL ERRORS
Blue front connector throttle grip position sensor - track A P0150
•
short circuit to positive / open circuit, short circuit to negative
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 39 of the ENGINE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 39 of the ENGINE connector.
Troubleshooting
•
shorted to positive: check the value shown by the parameter of the BLUE front connector
Throttle Grip Position Sensor - track A: disconnect the connector and read the value indi-
cated by the diagnostics 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 key set to ON, check that there
is power supply for the potentiometer PIN A and that PIN C 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

•
short circuit to positive / open circuit, short circuit to negative
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 13 of the ENGINE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 13 of the ENGINE connector
