Have a 08 uplander it has a code po449 I need a diagram of that evap system
heck engine P codes! Chevrolet uses an EVAP solenoid that is located under most vehicles near the gas tank and connects to the charcoal filter can. Codes can be set and will drive you crazy trying to figure out if you have a bad gas cap, broke lines---this is where they try to get you to do a smoke test, or you just think the vehicle is no good!

2008 chevy cobalt engine light on
Your Po449 code means: Evaporative Emission (EVAP) Vent Solenoid Control Circuit. Check to see if anything on you EVAP system has gotten disconnected and make sure that none of your hoses have gotten old and bridle or have holes. If everything looks ok, you probably have to replaced the Vent Solenoid Valve, which is located on the EVAP canister.
