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 upThat should have been all checked, BEFORE you spent timein line for inspectionIf all the codes are for real & not a false reportYou will need new spark plugs,ignition & fuel checked,new exhaust converters,new evap purge valve,new evapvent solenoid & possibly vacuum leaks resolvedYou either bought someones neglected vehicle or neverdo a thing but drive itMay be easier to get a different vehicle,your repair billwill start at $1,000 & go up, from not being proactive & takingcare of what is required in owning any vehicle (lack of knowledge)You will need the oxygen sensors also & no, they won't fix theamount, of what appears to be several failed items, all at one timeSo much for Toyota being better than other vehicles
