P0441 P0446 - How hard is it to fix?

[skewe]

2001 Camry 2.2

Have CEL 441 and 446 for the longest time and I have decided that I want to get rid of it. Toyota wanted to charge me $200 for labor.

Did lots of research from the recall about the VSV for 96-98 camry, etc.

Question:
1) How hard is it to get to and replace VSV and Charcoal Canister?
I am unable to find info / pics and Haynes manual was not too clear

2) What is the skill set required? I am not a mechanic but I m handy with tools. I have a decent set of tools (150pc).

3) Should i go with after market parts (Autozone) or Toyota parts

4) Anybody know where can i get the part # for VSV and Charcoal Canister?
Looked and look but i must be looking at the wrong area as i m not able to find it

A. Diagnostics for PO441:
1. Remove Vacuum Hoses between EVAP VSV and Charcoal Canister and discard.
2. If there is a metal vapor pipe between EVAP VSV and Charcoal Canister, clean inside of vapor
pipe
3. Replace EVAP VSV and Charcoal Canister assembly with new parts.
4. Install new vacuum hoses between EVAP VSV and Charcoal Canister.

B. Diagnostics for P0446:
1. Inspect vacuum hoses and pipes between EVAP (Purge) VSV and Charcoal Canister for leaks.
2. Replace Vapor Pressure VSV and Canister.
NOTE :When performing diagnostics for an occurrence of a MIL "ON" condition, Diagnostic
Trouble Code (DTC) P0441 may be result of debris in Evaporative Emission Control System. This
may cause blockage of a vapor line, or a stuck VSV, as described in troubleshooting area of Repair
Manual.

Question:
1) How hard is it to get to and replace VSV and Charcoal Canister?
I am unable to find info / pics and Haynes manual was not too clear-PRETTY EASY. THEY SHOULD BE ON THE LEFT SIDE OF THE ENGINE BAY NEAR THE TRANS.

2) What is the skill set required? I am not a mechanic but I m handy with tools. I have a decent set of tools (150pc).-THAT SHOULD BE FINE.

3) Should i go with after market parts (Autozone) or Toyota parts-DEFINATLY TOYOTA PARTS.

4) Anybody know where can i get the part # for VSV and Charcoal Canister?
Looked and look but i must be looking at the wrong area as i m not able to find it-GO TO THE DEALER AND TELL THEM WHAT YOU NEED. THEY HAVE THE EPC AND IF THEY HAVE A GOOD COUNTER PERSON, YOU SHOULD BE GOOD. IF NOT, LET ME KNOW AND I'LL GET YOU THE PART NUMBERS AND COST.

For service data, check the TN link to on-line service manuals in Camry General Posts. These may not be exactly the same year as yours, but close enough. For parts, some web based dealers sell Genuine Toyota at a discount.

I had this exact problem too. My suggestion it replace your gas cap gasket first. If thats not is the replace the charcoal canister. I ended up buying the charcoal canister and never used it cause it was my gas cap. The dealership sells the canister for around 300 bucks. Ill sell it to you for 190 plus whatever the shipping is. Its never been used and still in the original box.

for the p0446

it is the vsv for the charcoal canister

thats what the dealer told me

$50 for the part

seems pretty easy its behind the gas tank

I just havent fixed mine cause it has not effected drivability

but I will fix it some day

[Solorange]

I got the same code but then it went away after a while. It was my gas cap. As far as I know that vsv part of the charcoal canister. Thats why I bought a new canister because it came with all the valves. The dealership didnt mention that I could buy the vsv on the canister seperate. Thats interesting for me to find out if they just failed to mention it so they could make a few more bucks.

I thought it is below the car by the engine and not the gas tank

Many thanks. I did read up on the PDF prior to posting. I did a couple of hrs research, etc
(still unable to find part #). I will go to the dealership tomorrow and get the parts - VSV and the tube/pipe that goes to the VSV cos they suggested changing it.

Thanks for all your input..

I think there are 3 vsvs altogether. You might be thinking of a different one.

[Solorange]

I can think of only two vsv's.One up by the engine and one attached to the charcoal cansister. Make sure you replace the right one. You can test them to make sure they work. Its explained in the haynes manual how to do it.

Skewe- it depends on the year and engine. Some are back by the gas tank and some are in the engine bay.

I bought the whole chacoal canister cos i went to toyota today to get the ECAP VSV and they told me that it will be a custom order part for $60. Cannot return special order parts without restocking but can I can return in stock part (without restocking fee) if i cannot fix it so i will take a go at it.

The whole system part # is 77740-06170

Within the whole system, there are other components such as part # 89460-07030
90910-12264

Look at the image below, it is the square box and somebody pointed / marked it with red "fills with fuel".

cost was $256 brand new.

hope that i am replacing the right part

took it to the dealership after spending 4 hrs crawling under the car %^%
I took all the pipes out, which was a pain cos some sealed itself to the joints.
I was unable to remove the canister cos it was too big and I was unable to slot it though the gap between the exhause and the axel.

If the was no contact/pressure on the tires, i could have slot it though cos the tires / axel would be facing down and provided a wider gap.

It took the dealership 1 hr to get it out.
63$ well spent
