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.
