DTC P0116 Engine Coolant Temperature Circuit Range/Performance Problem: Description

DTC DETECTION CONDITIONS

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