P0449 Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction There is air escaping from the gas tank. Often a problem with the gas cap, try tightening the cap, reset the code and see if it comes back on. Essentially it is testing for cracks in the tank.

My check engine light is on in my 2008 GMC SIERRA 1500 pickup with 5.3 V8 I have 2 fault codes, PO449 & PO455. I tried removing battery cable no help. Can anyone steer me in righ direction. Thanks


First check the tightness of your gas filler cap as this can cause the codes to set. To erase the codes you will need a scan tool or code reader . Check the wiring and connections for the EVAP vent solenoid . Fuel tank pressure sensor may be bad .

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.

The check engine light should be on and there should be a code or codes in the computer which would tell you the cylinder in question.
If so, the problem could be ignition, fuel, or compression.
