Disconnect the sensor and short the two pins on the wiring harness and it should light up the WIF , the circuit is protected in the ECM. if the the light comes on , then you know the harness and ECM responded correctly with a state change, other simple way is remove the sensor and put it into a cup of water and you should get a WIF light on.
