2007 Escalade ESV 100k - I got the code P0449, light stayed on, no remote start (always happen when check engine light on) but the truck ran just fine, it just took for ever to fill tank as the nozzle kept clicking off. Replaced the Evap Solenoid Valve kit with harness (under spare tire) with the factory GM part with hoses and new vent filter. Started up, light still on, cleared code, light off for first time in weeks. Drove for 3 day, today on freeway light is back on. Check code, now it is reading P0446. I searched P0446 on this forum and zero results?????????????????
