Diy Code P0440 Fuel Ventilation Valve

the process was pretty simple except for locating the fuel vintilation valve. then the next difficult process was removing the last clip on upper rear of throttle body. I actually had to squeeze my left hand through the rear of alternator and right hand with a flat head slowly pushing on the clip to release it. The rest was pretty simple after I located the fuel vintilation valve. part cost $62 the dealer would have charged 400+ to do this. hope you guys like it!!

It really is. You can read up all you want about how to please a woman, you can look at all the diagrams in the world, but just like the clitoris, you won't know what the hell an apex is before you actually find it.
