| DTC P0117 (6-1): | ECT Sensor Circuit Low Voltage |
| 1. | Turn the ignition switch ON (II). |
| 2. | Check the ECT with the scan tool. Is 150°C (302°F) or higher (or H-Limit in Honda mode of PGM Tester) or 0 V indicated? YES - Go to 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the ECT sensor and at the ECM/ PCM.n |
| 3. | Disconnect the ECT sensor 2P connector. |
| 4. | Check the ECT with the scan tool. Is 150°C (302°F) or higher (or H-Limit in Honda mode of PGM Tester) or 0 V indicated? YES - Go to 5. NO - Replace the ECT sensor.n |

| 6. | Disconnect the negative cable from the battery. |
| 7. | Disconnect ECM/PCM connector B (24P). |
| 8. | Check for continuity between the ECT sensor 2P connector terminal No. 1 and body ground.
Is there continuity? YES - Repair short in the wire between the ECM/PCM (B8) and the ECT sensor.n NO - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away, replace the original ECM/ PCM.n |
