DTC 13: Engine Coolant Temperature (ECT) Sensor
- 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 "a" (Green/Red wire) and ground. See Fig 2. If voltage is about 5 volts, go to next step. If voltage is not about 5 volts, repair harness or connectors as necessary.
- Check Ground Circuit
- Turn ignition off. Check continuity between terminal "b" (White/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.
- Check Component
- Inspect ECT sensor. See I SYS/COMP TESTS article in the ENGINE PERFORMANCE section. Replace ECT sensor if necessary and perform FINAL CHECK in this article. If ECT sensor is okay, repair ECM pin terminals and/or wiring harness connector.
