Bravo to toyota for throwing away thier multiple vsv system and switching to a simple ventvalve and purge solinoid but they deffinatly droped the ball only making it a part of the canister..

Thank God!!!! That system was the most most f'd up up design i've ever seen. GM systems are beyond simple, purge valve to pull vacuum on tank, fuel tank pressure sensor to monitor vacuum, vent valve to dump the vacuum. Simple is better. Want to see one hell of a repair estimate?? Bring me a Toyota with an evap problem. I replace it all. The guys that work at the local Toyota dealer do the same thing.I really don't have the time to spend hours diagnosing multiple vsv's and a vapor canister with god knows how many little vacuum hoses and tees.

Key-off evap with self-testing vacuum pump is a lifesaver when it comes to verifying a repair. Too bad the canisters now list for around $900. 99% of Toyota evap DTCs are fixed by replacing the canister, which they hide above the rear subframe.

I couldnt agree more about gm's sytem being the easiest to diag, the only exception is cavaliers and malibus with the check ball in the filler area that you have to test the system then the filler neck or smoke it out from the filler neck Its a joke, no mater what is wrong your buying the canister... Even now with thier vent valve system you still gota relpace it... The one thing ive sceen a couple times,which i would like your input on is a brand new filler neck leaking because of a missed spotweld about 3/4 inch from the top.

They left that spot weld out, so you would have something to discover during a smoke test. It never ceases to amaze me the lengths some manufacturers will go to to make somebody's life miserable.

no they actualy missed the spot weld location. the spot weld was half on the part it should have been on and half off. the part that it overlapped onto was alot thinner and resulted in a small pin hole. probly just over .020"
