Hall Effect Sensor

Make all checks at the back of electrical connectors for EZK electronic control unit (ECU) with ignition on.

1. To test sensor supply voltage, connect voltmeter between terminal No. 10 and 4 of ECU. See the WIRING DIAGRAMS article. Voltmeter reading should be battery voltage.
2. To test signal from Hall Effect sensor to ECU, connect voltmeter between terminal No. 10 and 24 of ECU. Refer to the WIRING DIAGRAMS article. Slowly turn engine by hand Voltmeter reading should vary from 0.4 to 3.0 volts as Hall Effect sensor shutter opens and closes.
