ELECTRONIC THROTTLE CONTROL (ETC) / THROTTLE BODY

ETC OPERATION OVERVIEW

Mounted to the intake manifold, the throttle body
assembly provides the proper air/fuel ratio needed for
engine operation.
The throttle body assembly includes the Electronic
Throttle Control and Idle Air Control systems.
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 on the throttle body, the ETC
controls the throttle body. The ETC controls engine
throttle operation to provide the proper air/fuel ratio
needed for engine operation at all RPM ranges based off
input provided by the Pedal Position Sensor (PPS) and
Electronic Control Unit (ECU).

ETC TEST

q
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 / Throttle Body Replacement, page
4.34).
If code P1227 is being set, verify the following:
1. Check power supply voltage on pin for Pedal
2. Verify voltage at pedal for supply line. Troubleshoot
wiring
3. Check the pedal for sensor/physical damage (circuit
fault). Troubleshoot pedal 1 and 2 vs each other
(depending on faults)
