In the 2011–2016 Chevrolet Equinox and its sister vehicle, the GMC Terrain, the component commonly referred to as the "water sensor" is officially called the Engine Coolant Temperature (ECT) Sensor. This sensor tracks the temperature of the engine's liquid cooling mixture and transmits that data to the main computer.
