Of course it could be something other than the sensor itself; that's why if you want to be sure, the diagnostic steps located in the service manual for the given code need to be performed to isolate the exact cause. The fuel temp sensor isn't a major detriment to engine performance, but it does help, along with information from other sensors, let the ECM run the engine with more efficiency. The biggest issue is if the check engine light is "on," it will likely prevent the vehicle from passing state inspection when the time is due.
