Hyundai: 1999 Hyundai Tiburon 2.0L, hyundai tiburon, car campaign

Question
I got a readout from AutoZone and it said my problem code was P0422. Can you tell me what this means and if it can be repaired easily or do I need to take it to a dealer or repair shop.

Answer
Hi Shelby, the code P0422 means your manifold catalyst efficiency is low.  On your car, this catalytic converter is part of the exhaust manifold. I'd recommend calling your local dealer and seeing if there are any open service campaigns on your car.  Campaign V04 involves the inspection of the exhaust manifold and, if it's cracked, replacing the exhaust manifold.  If the campaign is still open on your vehicle and the manifold is cracked, you should get a new manifold and converter.If you have less than 80,000 miles on the car, the converter should be covered under warranty.  If you've got more than 80,000 miles and the recall is no longer open, presuming the check engine lamp and P0422 were the original reason for servicing, you should probably return to the original mechanic to request the vehicle be correctly repaired.  I'm figuring the mechanic either replaced the rear catalytic coverter (the one underneath the car) or replaced the manifold catalytic converter with one that isn't good enough.  In the former case, you should receive financial consideration because the mechanic replaced the incorrect converter, and in the latter, you should be entitled to a free repair because the installed part was defective.If the mechanic replaced the rear converter and not the manifold converter, you shouldn't have any issues with denial of warranty coverage.
