Having problems with your 2004 Pontiac Sunfire ?
Code p0455 on 2006 chevy impala
\015 Check engine light is on steady.\015
That code is for a large EVAP leak. The first thing I would suspect is a bad EVAP vent solenoid. You should be able to find it up under the car behind the drivers rear wheel. Remove it from the vehicle. use jumper wires to supply power and ground to the solenoid. You should hear a definite click and you should not be able to blow through it. If you do not hear a click and you can blow through it replace it.
