error code 0446

 Rookie

Getting the code po446. Have not done anything yet. Trying to find a common solution online. Looks like the evap canister needs to be replaced ~ maybe with all the valves? Whatever that means, it's apparently expensive. Not finding too many blogs/writings on this one as far as solutions go but the ones I have found pretty much say the same thing. Hope it's not too expensive a fix... Wonder if I will get better gas mileage or more power after it's fixed (I bought it this way...)

check engine light came on. mechanic told me it was probably the canister but that it didn't affect the engine so was okay to run with it. but time came for maryland emissions inspection, and it failed. mechanic now quotes $1500 to fix. Would like cheaper alternative! Would never have bought this car if I'd thought this kind of thing would happen this soon.

This just happened to me, too. Suddenly my check engine, 4WD + VSC lights came on when I started the car in the morning. Took it to my Toyota dealership for diagnosis, and it was the canister. They volunteered to cover it "as a courtesy to me because I've been such a good customer & have always had my vehicle serviced there". The repair would have cost over $1400, and most of that cost is parts, not labor. It only took 1 hour to correct it.

P0442, Evap leak - small. Check engine light comes on with the two VSC traction lights. My mechanic ran the Rav's self-diagnostic and that came back with no evap problems. But, 2 days after resetting the warning lights, all 3 come back on. If it's this evap cannister, I hope Toyota will help with the fix because I'm not putting $1500 into this car.

Happened once and our mechanic got one from junk yard that passed the smoke test for a total of $900 installed. 6 months later all of the lights and codes came back. We said we were not paying over $1,000 again and traded the car in for a Highlander. We loved the RAV4 but they need to redesign the Charcola Canister and fix the problem.
