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


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

My check engine light come up w/ all these code P0305,P0440,P0441,P0446 what's wrong Thanks


po305 is related to missfire on #5 cylinder
po440 is related to fuel tank pressure
pO441 is for evaporator purge flow malfunction
po446 relates to vent control valve electrical circuit malfunction

missfire is seperate from the other codes
as for the other three codes replace the vent control valve solenoid located near the charcoal canister the oth3er codes can relate to a faulty solenoid

after replacing light will only go out if you clear through a scan tool or three drive cycles of over 10 min each
