hi i notice my check engine like was on earlyer this week after returning from the hospital.. i took it a near by oil change place to have the code pulled up.

it says P0450- "fuel take pressure sensors too high for the application you are running" i believe-

does anyone know where the problem is occuring from or can pin point a good guess, since the oil change place wasn't any help at all.

thanks in ADVANCE, any help is greatly appreciated
