In the 2010 Ford Fusion, you can find the coolant temperature sensor in the coolant pipe positioned under the air intake pipe and behind the right cylinder head. This sensor, also referred to as an ECT sensor or ECTS, is responsible for monitoring the coolant/antifreeze temperature in the cooling system to determine the engine's heat output. A malfunctioning coolant temperature sensor can provide incorrect data to the computer, leading to inaccurate fuel and timing readings. It's relatively common for the sensor to fail and provide a consistently cold reading to the computer, which can result in decreased fuel efficiency and potential engine performance issues.
