ELECTRICAL

ECT SENSOR TEST
To quickly rule out other components and wiring related
to the ECT, disconnect the harness from the ECTsensor
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.

Polaris dealers can test the sensor by using Digital
Wrench® Diagnostic Software (dealer only).
