ELECTRONIC THROTTLE CONTROL (ETC)
OPERATION OVERVIEW
NOTE
DO NOT attempt to service the ETC. The ETC is a non-
serviceable component and can only be tested using
Digital Wrench®. If the ETC is faulty, the entire
assembly must be replaced.
Mounted to the intake plenum, the ETC acts as an
electronically controlled throttle body. The ETC controls
engine throttle operation to provide the proper air/fuel
ratio needed for engine operation at all RPM ranges. The
ETC controls engine RPM based off input provided by
the Pedal Position Sensor (PPS) and Electronic Control
Unit (ECU).
ETC TEST
Never attempt to disassemble the ETC assembly.
Warranty is void if the end cover is opened or tampered
with in any way.
All operating and control functions within the ETC are
pre-set. No internal servicing or adjustments may be
performed. If a problem is encountered, and you
determine the ETC to be faulty, contact the Polaris
Service Department for specific handling instructions. Do
not replace the ETC without factory authorization.
Use Digital Wrench® to perform all troubleshooting of
this component. Use a Volt Ohm meter to test the vehicle
harness continuity between the ETC connector and ECU
connector. Refer to the wire diagram for pin-out details. If
the ETC is faulty, the entire ETC assembly must be
replaced (see "ETC Replacement").
