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

Refer to DTC P0115. Refer to DESCRIPTION .

DTC No.	DTC Detection Condition	Trouble Area
P0116	Either of the following conditions is met (2 trip detection logic): When engine is started cold and warmed up, the engine coolant temperature sensor value does not change.
