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

WARNING: This page is about a different car, the 2006 Scion tC. However, it is still accessible from the selected car via links, so may be relevant.

Refer to DTC P0115 (see ).

DTC DETECTION CONDITION CHART

DTC No.	DTC Detection Condition	Trouble Area
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 remains within 1°C (1.8°F) of initial ECT	ECT sensor
