Evap Valve Code P0449

gunterbd · December 31, 2009

Really needing help with a EVAP valve issue. Maybe you guys (or gals) can direct me.

My EVAP VALVE went out and was repaired by my local GMC Dealer/Service Center. Being a die hard overfiller my problem has returned with the P0449 code. Did a quick search on this forum and found a few pics showing the location of the Evap valve. My problem is, I can't seem to locate the EVAP Valve. If GM made the repair they would have used the GM Service Kit/Upgrade and relocated the evap valve, right??? and if so where is it?????

It's location is in front of the gas tank, next to frame, where cab & bed come together.

I have replaced the evap solenoid and code went away on its own the next time i drove the truck. Part=$38

5/8" dia. heater hose 1 foot long and 2 hose clamps (around $5)

took about 10-15min to change

have you tried calling the dealer who installed the updated kit and asked ???...I'm not 100% if it is fact, but I read somewhere that it would be relocated above the tranny

Have you retired that die hard attitude towards filling?
