I have the CEL on with codes P0450 and P0496, from what I read the Fuel Tank Pressure Sensor or wiring to the sensor is usually the cause of P0450, is this true? Also, does anyone have a good EVAP diagram for a 2007 Hyundai Accent to aid in troubleshooting.

anytime a evap system has problems it should be smoke tested for leaks. that is about the only truefire way to detect a leak. unles it's a bad gas cap the fp sensor is normally the causeor wiring. unless you have already checked that then itcan be aleak.
