Was the service engine soon light on before you hit
the curb? If so, ignore the P0449 code for now.
Check the battery cable connections at both ends.
Including the pigtail ground connection on the
passenger's side fender and the positive cable
connection to the underhood fuse box. Remove the
cover from the underhood fuse box and make sure
the fuses and relays are in their slots securely and
there's no corrosion on any of the slots or battery
cable connections. The in car fuse box is next to the
glove box. Open the glove box door and look to the
right of the glove box. Make sure those fuses are
secure in their slots. The P0449 code is for the
EVAP system vent valve which is part of the fuel
pump assembly, as is the sending unit for the gas
gauge readout. A gas gauge that always shows full
or beyond full has a bad power (positive)
connection. So inspect the wires going to the gas
tank and make sure everything is clean and tight. It
sounds like when you hit the curb something
electrical got jarred loose. Hope that helps! Jim
