2006 Chevy Silverado-Emissions light on. told caused by DTC S P0449 & P0455. Large evapm leak & vent solenoid control circuit problem. Meaning???

The computer only checks for "leak" in the tank when the fuel is 15 to 85% full. So theoritically you could go fill the tank and have your local auto parts clear the code and the light would stay out till the fuel level dropped to 85% full and the computer desides to check your tank. Maybe in that short time period you could have your truck inspected.

P0135 is a bad 02 sensor
P0442 is a evap problem
P0449 is a vent solenoid

i would check the vent solenoid first its a 4ws fuse under the hood in the fuse box make sure you have power to it you should have power at all times the ground comes from the pcm i think if you fix this everything else will work they are all computer controled
