Hey guys, im new to this website and im also new to using forums so forgive me if i put this thread in the wrong place or something. I recently bought my first own car which is the 14' Note SV about a month ago and a half from a used dealership (Yeah, not a smart idea but was on a budget), the car has around 108k miles and it ran fine up until now. About a week ago or two i went over a speed bump just a tad too hard and my check engine came on and my car ended up going into a failsafe mode (correct me if im wrong) ended up not being able to over 45MPH or above 3000RPMs. Went to Autozone said it was my throttle positioning sensor and he gave me the code and what not saying it was low voltage input etc etc. But do you guys know what kind im suppose to get and if its easy to replace it myself? I dont wanna get the wrong one or mess anything up since im new with cars. As of now i temporarily clear the check engine light until i know what to get and where to fix it at, but when it comes back on it tends to do the same thing where i cant exceed those certain MPH or RPM limits and im worried itll do that while im on the highway.
