Q: How to remove and install a CHT sensor in Ford Fusion?
A: To remove the CHT sensor, remove the alternator air inlet duct. On 1.5L and 1.6L engines, remove the air intake duct and turbocharger inlet and outlet pipes. Disconnect the CHT sensor electrical connector and unscrew the sensor. V6 models, specifically 2010 and later, also have a CHT sensor. On 3.0L engines, it's in the rear cylinder head. On 3.5L engines, it's below the lower intake manifold. On 2.7L models, remove the engine cover fasteners to access the sensor.
