Hello and welcome to justanswer.com,
this code is for the fuel temperature pressure sensor in the fuel tank. this sensor senses pressure versus temperature to determine the amount of fuel left in the tank versus air/vapor.
there a lot of involved diagnostics involved in figuring out what the problem could be. My suggestion is if you are not technically inclined then i would take the car to the nearest Acura dealer so they can properly diagnose this for you.
please feel free to ask as many questions as you want. please do not rate my answer until we are completely done and you are completely satisfied. also that you can rate my answers good or above. thanks
