KENR6201-01
The loss of signal to the primary sensor and/or the
secondary sensor will result in one of the following
faults:
•
The loss of signal from the secondary speed/timing
sensor during start-up will prevent the engine from
starting.
•
The engine will continue to run when only one
sensor signal is present from either the primary
sensor or the secondary sensor.
•
The loss of signal from the primary speed/timing
sensor during operation of the engine will result in
engine operation in the derate mode.
•
Loss of signal from the primary sensor and the
secondary sensor during operation of the engine
will cause fuel injection to be terminated and the
engine will stop.
The primary sensor and the secondary sensor are
interchangeable components. If a sensor is suspect
the sensors can be exchanged in order to eliminate
a fault. If a secondary sensor is suspect and a
replacement secondary sensor is not available, then
the primary sensor and the secondary sensor can be
exchanged. This will allow testing to determine if the
secondary sensor is faulty.
