Malfunction Threshold
- Malfunction determination 1:
The ECT sensor 1 value [ECT Sensor 1] is less than 152.4°F (66.9°C) when the estimated engine coolant temperature reaches 172°F (78°C).
- Malfunction determination 2:
The estimated engine coolant temperature does not lower from 167°F (75°C), and the ECT sensor 1 value [ECT Sensor 1] is less than 140°F (60°C).
