Right side Throttle Grip Position sensor - track C P0152-
short circuit to positive / open circuit, short
circuit to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 30 of the ENGINE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 30 of the ENGINE connector.
Troubleshooting
•
shorted to positive: check the value shown by the parameter of the right Throttle Grip position
Sensor - track C: disconnect the right connector and see the value displayed by Navigator:
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
Right side Throttle Grip Position sensor - track D P0153
- short circuit to positive / open circuit, short
circuit to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 44 of the ENGINE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 44 of the ENGINE connector.
Troubleshooting
•
shorted to positive: check the value shown by the parameter of the right Throttle Grip Position
Sensor - track D: disconnect the right connector and see the value displayed by Navigator:
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
