Typical Malfunction Thresholds
ENGINE COOLANT TEMPERATURE SENSOR COLD START MONITOR
| Engine coolant temperature sensor value change | Less than 5°C (9°F) |
ENGINE COOLANT TEMPERATURE SENSOR SOAK MONITOR
| Difference between current engine coolant temperature sensor value and previous engine coolant temperature sensor value when engine stopped | Less than 5°C (9°F) (varies with engine coolant temperature of last trip engine stop) |
