  1. Turn ignition on. Check ECT using scan tool. If 302°F (150°C) or more is indicated, go to next step. If 302°F (150°C) or more is not indicated, problem is intermittent. System is okay at this time. Check for poor connections or loose wires at ECT sensor connector and PCM connector. See the «WIRING DIAGRAMS»(ref-16319) article.
  2. Disconnect ECT sensor 2-pin connector. Check ECT using scan tool. If 302°F (150°C) or more is indicated, go to next step. If 302°F (150°C) or more is not indicated, replace ECT sensor. 3) Turn ignition off. Disconnect PCM 16-pin connector "D". (Схема №2) Check for continuity between ECT connector Red/White wire and ground. If continuity exists, repair short in Red/White wire between ECT sensor and PCM connector terminal D2.
