My 02 camry le failed emmission test whats wrong error codes po440, po441, po446, po420

Needs a new vapor pressure sensor to correct p0446, p0441... My suggestion is to get one from the junkyard since it's over 200 bucks. Your catalytic converter issue can be corrected using this stuff called 'Cataclean.' Follow the instructions on the bottle. Use high mileage seafoam. May not be a permanent fix, but it will be enough to pass smog and cheaper.

You have codes for a failed exhaust converter,PO420,
EVAP System problem PO440,Incorrect Purge Flow PO441,
Evap Vent Control issues,PO446

Your car is all messed up

That should have been all checked, BEFORE you spent time
in line for inspection

If all the codes are for real & not a false report

You will need new spark plugs,ignition & fuel checked,
new exhaust converters,new evap purge valve,new evap
vent solenoid & possibly vacuum leaks resolved

You either bought someones neglected vehicle or never
do a thing but drive it

May be easier to get a different vehicle,your repair bill
will start at $1,000 & go up, from not being proactive & taking
care of what is required in owning any vehicle (lack of knowledge)

You will need the oxygen sensors also & no, they won't fix the
amount, of what appears to be several failed items, all at one time

So much for Toyota being better than other vehicles
