NOTE: If the servomotor cycles
three times and then shuts down, the
exhaust valve cables are not
adjusted correctly. The exhaust
valves may also be sticking.
NOTE: APV cleaning may be done
by the snowmobile owner if qualified
to do so. If the owner does not feel
qualified, take the snowmobile to an
authorized Arctic Cat Snowmobile
dealer for this service. This service
is at the discretion and expense of
the snowmobile owner.
Exhaust Controlled
Timing (ECT) System
This system automatically adjusts the
ignition timing to provide maximum per-
formance through a variety of operating
conditions. The ECM receives input on
engine RPM (demand) and exhaust pipe
temperature (engine condition) and
adjusts the ignition timing accordingly.
This system is not adjustable and is main-
tenance free.
If a system fault is suspected, use an ohm-
meter to check continuity of the exhaust
pipe temperature sensor located in the
expansion chamber. A reading of either 0
ohm or infinity indicates a failed sensor.
NOTE: A disabled ECT system
WILL NOT cause engine damage;
however, a failed ECT system will
have slower throttle response and
may produce slightly less top-end
performance.
