More often than not, the Vacuum Switching Valve for the EVAP has failed. This is assuming that alll of the vacuum lines are good, and there is no damage or cracks in any of the moulded plastic connectors under the tank. You need to go to a Toyota dealer & purchase the Evap VSV, part number 90910-12264; expect to pay about 50 dollars for the switch. You can't buy this switch at an auto retailer such as AutoZone; it's a dealer item only. Hope this helps, and the graciousness of a "FixYa" would be much appreciated. Thnaks for choosing FixYa!

I have a 98 Camry with this code. The primary cause of the PO446 code is a loose gas cap. I have found that my Camry had rust around the mouth of the fuel tank filler and rust imbedded in the rubber seal. It couldn't get a consistent seal due to the rust! I stuffed a rag in the filler port to keep debris out of the tank and sanded off the rust. Five months later the PO446 code came back, but when I checked the filler port, it was again rusty. I've polished off the port sealing surface, painted it with clear spray paint, and cleaned off the seal on the cap once again. I suspect Toyota has a corrosion problem on the filler ports of a lot of their cars. Look for the telltale ring of rust on the seal. Once you know what to look for, it is easy to see.

1998 toyota camry, 2.2L 4 cyl. P0325, P0441 and P0446 trouble codes

Code 325 is for a problem with the knock sensor circuit, code 441 is for an incorrect flow with the purge valve and the vent for the gas tank, and code 446 is also for the vent control circuit.
I would clear the codes and see how many come back after a test drive. You may need a shop manual to test the circuits.

Hi. I recently bought a OBDII scanner because my 1998 toyota camry has a check engine light turned on. I got six codes, scary. P0171, P0446, P1130, P1133, P0171 pending, P0446 again. what do all this codes...

there should have been a code book with the OBDII. If not take the codes to a garage near you and ask them, they might give you your answers. If not, I will bookmark this page and see if I can find my book and get back to you. RT

I have a 98 camery and po446 came up at the smog check how can i fix

Your problem is in the Evap. Emission System. I have seen hundreds of P0446 codes on Camry like yours. 90% of the time it is caused by a bad tank by-pass valve (VSV) on the charcoal canister. You can check the valve by removing it and applying power to one pin and ground to the other. The valve should click... you'll hear it and feel it. Sometimes the valve sticks intermittently, and you may not experience it when testing it.
The P0446 can also be caused by a bad Canister Control Valve located
on the air filter housing. You can test it the same way. This valve
turns on and kind of clicks rapidly when power and ground are applied.

There can also be a leak in the evaporative system. This is very
difficult to find, and you'd need special equipment to test for a
leak. Your best bet is a mechanic.They see the P0446 everyday, and
they'll be able to diagnose the problem relatively easily. Usually
they charge 1 hour labor to diagnose it. From there you can repair it
yourself if you want.I hope this helps and good luck.

Toyota camry 1997 3.0 v-6 code p0446

That code is for the evaporative emmisions system. Here is a link to an open forum you can go to, this will help you understand what it is, and why. The vehicle on the site is a van, but the code, and parts involved are one in the same, so don't worry about the difference in vehicle. The van is a toyota, and this is the information on the p0446 code. Hope this helps you.

1998 toyota camry V6

P0420 indicates you have a catalyst efficiency issue; replacement of the Air-Fuel Sensor should take care of that;
The P0441, P0446 and (I assume P0440); you said 446 twice, indicates a faulty or loose fuel cap; it is not sealing properly.
Please feel free to respond to me if you have any further questions.
A FixYa rating from you regarding my assistance would be greatly appreciated.
