DTC P0117: ENGINE COOLANT TEMPERATURE SENSOR LOW VOLTAGE INPUT Honda CR-V I рестайлинг

  1. Turn ignition on. Check Engine Coolant Temperature (ECT) sensor using scan tool. If 302°F (150°C) or more, or zero volts is indicated, go to next step. If 302°F (150°C) or more, or zero volts is not indicated, problem is intermittent. System is okay at this time. Check for poor connections or loose wires at ECT sensor and PCM connectors. See appropriate wiring diagram in WIRING DIAGRAMS article.
  2. Disconnect ECT sensor 2-pin connector. Check ECT sensor using scan tool. If 302°F (150°C) or more, or zero volts is indicated, go to next step. If 302°F (150°C) or more, or zero volts is not indicated, replace ECT sensor.
  3. Turn ignition off. Disconnect PCM 31-pin connector "C". Check for continuity between ground and ECT 2-pin harness connector terminal No. 1 (Red/White wire). If continuity exists, repair short in Red/White wire between ECT sensor and PCM 31-pin connector "C" terminal No. 26. See appropriate wiring diagram in WIRING DIAGRAMS article. If continuity does not exist, substitute a known-good PCM and recheck. See SUBSTITUTING PCM in SELF-DIAGNOSTICS - INTRODUCTION article. If symptom or indication goes away, replace original PCM.
