DTC P0116: Engine Coolant Temperature Circuit Range / Performance [12/2015 - 08/2016]: Description

WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.

Refer to DTC P0115 (Refer to DESCRIPTION ).

DTC No.	DTC Detection Condition	Trouble Area
P0116	When either of the following conditions is met (2 trip detection logic): When cold engine started and engine warmed up, engine coolant temperature sensor value does not change After warmed up engine stopped and then next cold engine start performed, engine coolant temperature sensor value does not change	Thermostat Engine coolant temperature sensor
P0116	For Mexico Models: Case 1: Engine coolant temperature 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) (a) Vehicle driven at varying speeds (accelerated and decelerated) (b) Engine coolant temperature remains within 3°C (5.4°F) of initial engine coolant temperature Case 2: Engine coolant temperature more than 60°C (140°F) when engine started, and conditions (a) and (b) are met (6 trip detection logic) (a) Vehicle driven at varying speeds (accelerated and decelerated) (b) Engine coolant temperature measurements remain within 1°C (1.8°F) of initial engine coolant temperature on 6 successive occasions	Thermostat Engine coolant temperature sensor
