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).
