i found myself unable to refuel my tiburon once, it seemed to be full but i knew better. a guy at the gas station said, "oh yeah just unplug this wire here, that'll fix it" all i really remember was "this wire here" was under the car, near the fill door. it solved my fuel rejection problems pronto. only downside is every other day someone says "what's that wire hanging down under your car ?"

 

Solenoid for the evap charcoal canister?

 

probably what that wire is. anybody else got any say in effects of doing that?

 

i drove for about a year or two after unplugging that without any side effects. mileage stayed around 30.

 

troggdor so you didn't get a cel for the unplugged wire?

mannyr if there is no code thrown scratch replacing the valve?

 

there should be a code if either one is unplugged or gone bad.

 

Ok i'm going to ask a really really dumb question. Which PCV Valve is this? is it the golden metal one that Autozone sells? I've got that one.

 

PCV = Purge Control Valve: EVAP related

PCV valve = Positive Crankcase Ventilation valve, -the one on the back of the valve cover, not EVAP related
