2003 Buell XB9R: Fuel System 4-79
HOME
TROUBLE CODE 44 4.26
GENERAL
NOTE
See Figure 4-171. When vehicle lean angle causes weighted
pendulum to enter shaded area for a period of greater than
one second, ECM shuts off ignition and fuel systems.
Bank Angle Sensor
See Figure 4-170. A Code 44 occurs when the bank angle
sensor (1) voltage is outside the normal operating range of
0.25-4.8 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.
