DTC DETECTION CONDITION AND TROUBLE AREA REFERENCE

DTC No.	DTC Detection Condition	Trouble Area
P0116	ECTs as listed below are nearly same (2 trip detection logic): ECT when engine is started at lower than 60°C (140°F) of ECT ECT when engine is warmed up	Thermostat ECT sensor
	ECTs as listed below are nearly same when engine is started at higher than 60°C (140°F) of ECT (2 trip detection logic) ECT when engine is stopped after driving ECT when engine is started at lower than 60°C (140°F) of ECT
	When either of following conditions is met (2 trip detection logic): When cold engine started and engine warmed up, Engine Coolant Temperature (ECT) sensor value does not change After engine is warmed up, ECT sensor value does not change when engine stopped and then next cold engine start is performed
