GMC 2006 5.3 1500 p/up.....

J1850 VPW code

PO449 Evap Mission Control System Vent....


anyone with a clue as to the actual failure history and where to look??

~same code some time ago on a buddy's S10 of near same year....and it was NOT the solenoid.....so after spend some bux on it, he just scratched out on the problem, never did fix it....

anyone??

GM usally has a very long emmisions warranty on there cars. I know it's in the 5 year or 7 year range. If the CEL is on that would be covered whatever it is.
