Could be charcoal canister? Replaced mine and it was about 600 bucks. Might just be the gas cap though

Default ES300 441 and 446 codes

I already replaced the original gas cap with one from AutoZone. The light stayed off for 2-3 weeks. When a perspective buyer test drove it, the light came back on

I don't ever drive on the highway and I drive less than 50 miles per week. Could going over a certain speed mean anything?

Default ES300 441 and 446

Since the car is for sale, I am trying to get the codes cleared and to make sure that the person who purchases the car gets a car in proper working condition. I also don't want to overpay for a big repari if all it needs is something simple.

The CEL will come on again after a two trip logic dectection. You must fix the problem to be gone. Masking it will not do anything. Since you dont want to fix it. Just simply tell the buyer the problem and give them a discount. Just an advice

Tx. You misunderstood me. I do want to get it fixed before I sell it. I just want to limit the repairs to what actually is wrong and not pay for repairs that are not necessary.

I'd check the charcoal canister, the car will drive the same, but the CEL will be on. I dont know how it is in Florida but a car in New York can't have CEL if it wants to pass state inspection, this is the only reason i changed it

I don't think they check that in FL but it doesn't matter because I will have it fixed anyway.
I have an appointment on Monday with my mechanic. Someone on here says that there are 2 VSV's on my car. I don't know. Here is what I will have him do:

Code 441 - 446

1. Replace Gas Cap ALREADY DONE
2. Check hoses
3. Check Air filter
4. Get a smoke test done
5. Check for Cracked or loose Hose
6. Check connections especially to VSV
7. Check for Vacuum leak
8 Check.Air filter (I think mine is new)
9. Check Charcoal canister
10. Check VSV

I am almost positive those are the same codes that came up when my charcoal canister went bad, if you get it changed at the dealer it is about 500-600. My uncle replace dhis own in his avalon and the used part ws about 200

This might sound dumb of me to ask and I know it is but isn't the canister part of the vsv?

I just talked to my mechanic. He says that he thinks it's the vsv. He will have it ready tomorrow. He said the part was $108 and the total bill will be $288.

He said the canister checked out fine. He said he ran two smoke tests. The first time everything checked out fine, but when he ran it a second time he found the problem. It will be ready tomorrow.

If this is the end of the problem then I will be very very happy.

Bumping this thread because I have the P0446 code, but not P0441. Is that indicative of just a VSV problem, a charcoal canister problem, or both?

Bumping this again (although at this point it's more for personal reference) because P0446 came back yesterday after exactly 11 months. What I did about a year ago was pretty simple - reset the codes and reseat the gas cap. I've driven about 10,000 miles since then over the course of 11 months until the code came back. I followed the same procedure last night so we'll see how long it lasts this time.
