Question about 2003 Kia Sorento
Codes are po431 and po446
can you tell me what this it?
I would suggest to change the cat convertor and move on.This will solve your problem and most likely check engine will go a way.Your code is P0431 is related to bad cat not sensor.Over time the cat will store too much carbons and will make it stop from firing up.Bank 1 cat is the driver side and bank 2 is th cat by the passenger side.You can get remanufacture cat at low price and around the $250 rather than by it from the dealer will cost you arm and leg around $800.I hope this will give anyone a good feedback.Mojeer

P0431 :- (warm up catalytic converter bank 2 - efficiency below threshold )
test the catalytic converter it locate in exhaust gas pipe
test the heated oxygen sensor in exhaust gas pipe too near the engine
P0446 :- (evaporative emission (EVAP) system , vent control , circuit malfunction )
test wiring , EVAP canister purge valve , ECM engine control module
just ask for more abut DTC
