- Crank engine and observe LED light on tester. If LED flickers, Hall Effect sensor is okay.
- If LED does not flicker, remove harness connector from Hall Effect sensor on distributor. Connect multimeter to outer connections of harness connector. Turn on ignition. Voltage to Hall Effect sensor from ECU should be 9 volts minimum. If voltage is low, check battery, battery cables, all wiring and ECU.
