Set Condition: LOW LIMIT: The ECT Sensor value is less than -39°C (-38°F) for more than 1 second. HIGH LIMIT: The ECT Sensor value is more than 170°C (338°F) for more than 1 second. CLOSED LOOP TEMPERATURE NOT REACHED: The engine coolant temperature does reach 15°C (60°F) in a predetermined time. Failure time varies from 2 to 20 Min and is calculated from start up temperature, engine speed, and ambient temperature.
