Question about 2002 Toyota Camry
I own a 2002 Toyota Camry - 4 cylinder engine. My wife went to Auto Zone and the error codes they found were: P440, P441, P446. We are going to try another gas cap, try that. Does anyone have any solution(s) for me? Based from what I could find, previous owners were having trouble either putting gas into the car and/or problems starting the car. Our car starts great, runs normally, other then it's showing that it's a 7 years old vehicle. If anyone has any solutions, that would be outstanding!
I am not going to lie, I came across this in another forum a while back and I would love to retype it and interpret it here but it is too much. I looked at it and verified that the information here is information that could be found through my scan tools so here it is!
The fuel tank pressure is atmospheric pressure after the vehicle is driven for 20 min (2 trip detection logic).
Fuel tank cap incorrectly installed <= Most common
Fuel tank cap cracked or damaged (Toyota part only)
Bad vapor pressure sensor/circuit
Vacuum hose cracked, holed, blocked, damaged or disconnected
Hose or tube cracked, holed, damaged, or loose
Fuel tank/filler neck cracked, holed, or damaged
Charcoal canister cracked, holed, or damaged (collision)
In above description, check hoses between vapor pressur sensor and VSV for vapor pressure sensor and charcoal canister. Also, hose between charcoal canister and fuel tank.

All the codes you posted are definitely for the evaporative emission system. Try tightening the gas cap first and have the codes cleared with a scan tool. You can leave the codes the way they are and drive the vehicle, it may take a few hours of driving for the Evap system to run its tests and clear the code if the is no problem. Gas cap seals are known to leak. The evap system is in place to not allow gasoline vapors to escape . The sytem will pull your gas tank into a vacuum and burn the vapors in the engine. If the gas cap trick does not work, you may have a wiring or evap line problem. A repair shop will put smoke from a machine into the system and check for leaks.
