| Diagnosis delay time | — | ||||
| B | Diagnosis condition | — | |||
| Signal (terminal) | Engine coolant temperature sensor signal | ||||
| Threshold | Engine coolant temperature signal from engine coolant temperature sensor does not fluctuate, even when some time has passed after starting the engine with pre-warming up condition | ||||
| Diagnosis delay time | — | ||||
