DTC P0116 TROUBLE DETECTION REFERENCE

DTC No.	DTC Detection Condition	Trouble Area
P0116	Case 1: Engine Coolant Temperature (ECT) is between 35°C and 60°C (95°F and 140°F) when engine started, and conditions (a) and (b) are met (2 trip detection logic): Vehicle driven at varying speeds (accelerated and decelerated) ECT change is within 3°C (5.4°F) of initial ECT Case 2: ECT is more than 60°C (140°F) when engine started, and conditions (a) and (b) are met (6 trip detection logic): Vehicle driven at varying speeds (accelerated and decelerated ECT measurements change is within 1°C (1.8°F) of initial ECT on 6 successive occasions	ECT sensor
