4-84 2007 Buell Firebolt: Fuel System
HOME
TROUBLE CODE 44 4.27
GENERAL
NOTE
See Figure 4-59. 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 4-60. A Code 44 occurs when the bank angle
sensor (1) voltage is outside the normal operating range of
0.24-4.79 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 will continue to run and can be
ridden to the dealership for repair.
