Yamaha code 11 14 15 20

11 - Cylinder Identification Sensor
14 - Intake Air Pressure Sensor (Pipe System)
15 - Throttle Position Sensor (for Throttle Valves)
20 - Intake Air Pressure Sensor / Atmospheric Pressure Sensor

from what ive had in the past
your issue is with the first of the fault codes
11 - Cylinder Identification Sensor

check your engine wiring harness with a bright light or torch around the fan or fan housing by the radiator
look for nicked or cracked wiring
the sensor wire has a tendency to get nicked by the fan
but you can repair or replace
please see pics
pic (1) nicked Cylinder Identification Sensor wire


pic (2) repair with connection blocks or solder together


pic (3) wrap with insulation tape after repayamaha code 11 14 15 20 - dsc01263.jpgsrc="/uploads/images/dsc01263.jpg" alt="dsc01263.jpg" class="h_mi" />

once you have done the repair
try to reroute the wire away from the fan and housing
if that fails get a new sensor

have fun
