TROUBLE CODE 44 4.26
GENERAL
Bank Angle Sensor
See Figure 4-62. A Code 44 occurs when the bank angle
sensor voltage is outside the normal operating range of 0.6-
1.1 volts. This may be caused by:
● Short to ground in harness between sensor and elec-
tronic control module.
● Short to voltage in harness between sensor and elec-
tronic control module.
● Failed sensor.
If this code occurs, the engine may stop running. The engine
may still be restarted and ridden to the dealership for repair.
