Hi All,
I just got a Service Engine Soon light...scanned for a code and got a P0447...bad vent control valve.
In checking the on line part for Infiniti...there's 2... One in the engine bay (14920)...and there's one underneath
the car near the gas tank (14920-A).
Do I need to get both of them? The one in the engine bay seems easier to
get to...while the one underneath is a b*tch! (I haven't been able to get the wire connector off! Also I can't rotate
the valve enough and I may have to take the "box thing" it's attached to off...but I can't figure out how!)
Any insight?
TIA,
MP-In-The-Wind

 

There is only one canister vent control valve and that is the one in the back. These two threads will have more information on the valve and how to DIY it:
Thread #1
Thread #2

Should be p/n: 14935-AM600 but I suggest you verify this against your VIN before you buy.

 

Thanks ILM-NC G37S.... The part is due in next week...I'll give it a shot!

 

OK, I got the part...but I can't remove the old one...as I can't turn it enough to have it pop out.
I've read the above 2 threads...and it looks like it involves breaking the old part and filing the new part down.
Can anybody tell me how to remove the Evap cannister?

 

Well...I completed the job a couple of days ago...there is NO easy way to remove the evap canister other than taking off LOTS
of covering pieces...which on a 15 year old car (2008) means lots of broken off bolts... I reset the light...and it hasn't come
back on since.
