Having problems with your 2006 Chevrolet Impala ?
Code p0455 2006 chevy impala
\015 Check engine light is on steady. Got it check and the code p0455 came up. What could it be if it's not the gas cap?\015
That code is for a large EVAP leak. The first thing I would suspect is a\012 bad EVAP vent solenoid. You should be able to find it up under the car \012behind the drivers rear wheel. Remove it from the vehicle. use jumper \012wires to supply power and ground to the solenoid. You should hear a \012definite click and you should not be able to blow through it. If you do \012not hear a click and you can blow through it replace it.
