ECT Sensor Test
To quickly rule out other components and wiring related
to the ECT, disconnect the harness from the ECT sensor
and start the engine. After a few seconds, the fan should
turn on and the “Check Engine” indicator should display
on the instrument cluster. This indicates all other
components are working properly.
Refer to Chapter 3 and 10 for additional ECT sensor
information. Polaris dealers can test the sensor by using
Digital Wrench® Diagnostic Software (dealer only).

ECT Sensor Replacement
1. Remove the throttle body. (see Chapter 4 – Throttle
Body Removal, page 4.34).
2. Be sure the engine has cooled enough to work on.
3. Disconnect the vehicle harness from ECT sensor.
4. Drain the coolant so the level is below the sensor
(see Chapter 2 – Coolant Drain / Fill, page 2.29).
5. Using a wrench, remove and replace the sensor,
applying a light coating of thread sealant to aid
installation.
6. Torque the new ECT sensor to specification and
connect the vehicle harness to the sensor.
ECT Sensor:
