02 4Runner 112K 4WD Sport. I tried searching, but to no avail I couldn't find pics of the VSV location. I have a FSM but it only gives general location. Anyone that has done a DIY can either describe the location exactly? A pic would be better. There are so many hoses and wires.
I have a P0440 code and the gas cap was kinda loose. It may be that, but I may have overfilledthe gas but I think that causes a different code according to the FSM?
What did you guys use to clean / flush charcoal canister?? I will probably want to replace the VSV and clean the charcoal canister if the light pops on again and the gas cap it tight. I checked underneath, but no loose hoses and I can't see any damage to the cannister.

 

here's a diagram of the VSV. the valve is the one numbered 17650E

hth

 

Thanks KZN185W. Which direction is the front of the vehicle?

Anyone on the chemical used to clean the charcoal canister? Carb and choke??

 

subscribed! i have the part chillin. just waiting for warmer weather and a good write up or even just a few pix of where the heck this thing is. i should just go look for it. yota tech spoils me

 

P0440 is the "large leak" code...99% of the time it is because of the loose gas cap...

 

the front of the vehicle is towards the lower left corner of the diagram

 

Anyone on what to clean the canister with? All write ups are no longer working.......

 

Lower left? So the ends of the hoses are toward the vehicle?
Which side of the vehicle is the VSV on?

 

I think it is but just in case it comes on again.
Should I just get a new gas cap? How long do these last in a climate that gets hot and cold?

 

It doesnt hurt to get a new cap. I replaced mine a few months ago and at first though it was the wrong part since it was white and not ghetto yellow and the grommet actually snugs up.

 

it is should be on the driver's side, somewhere near the brake master cylinder.

sorry, i can't give you a specific location as i'm just basing it on the diagram. i have a TDIC which has a different vsv setup

 

I think you are talking about the one under the hood. There are 3 different VSVs. One by the charcoal canister, 2 by the EGR in a row. I found the ones by the EGR in the back of the engine. The dealer said that they don't even stock those......But the service said they replace them ALL the time???? I think that service advisor was full of crap and had it spewing out his ears.
So, to get the truth, I called another dealer. They told me everything opposite to the first! WTF!? The 2nd dealership parts department told me that the one by the charcoal canister is the one they replace the most but by far way more gas caps go bad. What service said and parts said coincided. I guess I know who to trust now.

Question: Do you have a diagram of the one by the charcoal canister?

I will go get a new gas cap today only $18. I asked them if they would test mine on the truck, it cost $25 Itiots.

 

sorry, i don't have the diagram

 

for my 2002, the charcoal canister is right under the spare tire. its the big square plastic thing and its a pain in the a$$ to get out!

 

One of the VSVs is located right in front of the canister. The other 2 are located under the hood on the inside of the driver side front fender. It has a green tag that says "EVAP SERVICE PORT". Follow that toward the driver side fender and there you have the VSV for CCV and VSV for EVAP. As far as the VSV for VPS, you have to remove the canister to replace it. The biggest hint I can give is that there is a clip that is hard to see toward the front of the vehicle. You can see it if you look straight up directly between the crossmember on the frame and the rear diff / axle. Use a LONG flathead screwdriver to pop it off. It is right next to the furthest forward bolt holding the bracket with the canister on to the underside of the vehicle.
