- Check Power Supply
- Turn ignition off. Disconnect ECT sensor harness connector. See Fig 1
. Turn ignition on. Measure voltage between ECT sensor harness connector terminal "b" (Yellow wire) and ground. See Fig 2
. If voltage is about 5 volts, go to next step. If voltage is not as specified, repair harness or connectors as necessary.
- Check Ground Circuit
- Turn ignition off. Check continuity between terminal "a" (Black wire) and engine ground. See Fig 3
. If continuity is present, go to next step. If continuity is not present, repair harness or connectors as necessary.
