We're is the cylinder head temp sensor

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your vehicle. On the Fusion, the cylinder head temperature (CHT) sensor is usually located on top of the engine between cylinder two and cylinder three ignition coils. Depending on your engine model, it may be mounted on the exhaust manifold. Sometimes, it can be hidden by wiring or other engine components, making it hard to spot. If you're still having trouble finding it, a repair manual for your engine type can give you an exact diagram. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
