4-84 2007 Buell Lightning: Fuel System

HOME

TROUBLE CODE 44 4.27

GENERAL

NOTE

See Figure 4-61. 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 4-63. A Code 44 occurs when the bank angle

sensor voltage is outside the normal operating range of 0.24-

4.79 volts. Refer to Table 4-31. 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.
