Monitor Scantool Data

  1. Engine "ON".
  2. Monitor Engine Coolant Temperature Sensor parameter on Current data.
  3. After the engine has been starting, Check that ECT rises steadily to about 90°C (194°F) and ECT stabilizes when the thermostat opens.
    1. Specification: ECT rises steadily to about 90°C (194°F) and ECT stabilizes when the thermostat opens.

  4. Is Current data displayed correctly?

    YES

    • Fault is intermittent caused by poor contact in the sensor's and/or PCM's connector or was repaired and PCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
