[kenny6683]

i just started working on this issue
Check Engine Light P0446 was lit
Tools needed: needle nose pliers, flat head screw driver, 14mm socket with short extension and rachet
Suggested tools: Safety glasses and mechanic gloves ( alot of dirt and debris)

1999 Canister Part number 77740-06093
2003-2004 Canister. Part no: 77740-06170 (i ordered wrong one)

Location of Charcoal/Vapor Canister between fuel tank and spare tire


should remove hose in this area to have easier access to the 14mm bolt



This plug was very annoying to remove...be patient with it
i broke plastic ring which holds it in place. i believe ring should be squeezed and then pulled but its very
tight in this area which makes it tough


inserting new canister...it will get a bit scratched as i didnt remove muffler or any other parts
do not force it in...just keep moving it around until you find perfect angle. if you force it you might brake valve or hose connections

after installing this brand new canister and with all new assembly
I came up with code P0441 now...which is the valve on canister
i think i connect hose wrong, so today i took it off again and changed 2 of the lines on canister
i pray the code does not return...i will let you guys know.
if it does...i will change the 3 original rubber hose which come from gas tank (these did not come with new canister and may be clogged/ dirty)

so i ordered the wrong canister..
the 99 and 2000 model changed a bit
VSV is different on them.
The 99 has 3 inserts and the 2000-2003 models have only 2.
now i need a new VSV since i already tried using the one i purchased (sucks) and they will not exchange it

I plan on doing this very soon
I knew about the different model versions though
it sucks but maybe u can get half your money back selling it off on ebay or these forums
tons of people probably need this

yeah sucks but i am still trying to make canister work on my car.

i removed old VSV (pressue switching valve) from old canister and replaced new valve with old one
i know the VSV may be the problem but this is the only way to find out at this point.

here is a pic of new one next to old one
2000-2003 valve compared to 1999 valve




if code returns as P0446 then i know all i need is a new VSV.
if any one needs a VSV for 2000-2003 brand new for sale $40 shipped
