Circuit/System Verification

  1. Observe the engine coolant temperature (ECT) sensor parameter with a scan tool while moving the ECT sensor connector and the engine control module (ECM) connector. The ECT sensor parameter should not fluctuate while moving the related harnesses and connectors.
    • Repair the suspected harness or connection if the ECT parameter fluctuates more than 3°C (5°F) while moving the related harnesses and connectors.
  2. Inspect the engine coolant level. Verify that the cooling system is operating correctly.
  3. Operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. DTC P0119 should not set.
