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

Refer to DTC P0115 ENGINE COOLANT TEMPERATURE CIRCUIT; DTC P0117 ENGINE COOLANT TEMPERATURE CIRCUIT LOW INPUT; DTC P0118 ENGINE COOLANT TEMPERATURE CIRCUIT HIGH INPUT .

DTC DETECTION CONDITIONS REFERENCE

DTC No.	DTC Detection Conditions	Trouble Areas
P0116	Case 1: Engine Coolant Temperature (ECT) is between 35°C and 60°C (95°F and 140°F) when engine is started, and conditions (a) and (b) are 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 is more than 60°C (140°F) when engine is started, and conditions (a) and (b) are 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
