P0422 - 2001 Elantra
Hi Hyundaitech!
You probably don't remember my unrealistic optimism that P0422 might only be an O2 sensor problem, from a post in June, which you helped bring to ground. (It still seems weird to me that the car would be diagnosing a bad cat so soon after getting perfect marks on a smog check). Well, if I am to bite the bullet, do I need to replace both Cats? In yet another display of optimism (do I never learn...), I'm hoping I can get away with replacing only the exhaust manifold+cat for a mere $161, and not the front pipe+cat, which runs $743. Yet my gut tells me that the more expensive one would be the more important one, and (unless I'm having a brain fart) they're both between the upstream and downstream o2 sensors. Thanks! -Matthew |

Unless your car has a different setup than most I've seen-- that's possible
since different localities have different emissions setups-- you have one oxygen sensor in the manifold prior to the manifold converter and one in the front pipe behind the manifold converter and in front of the rear converter. I've seen no vehicles (of your vintage) with a sensor behind the rear converter. So, it'd be my assessment that you only need to replace the manifold assembly (which includes the front converter). Also, if you're the original owner, you may be able to get this covered under the powertrain warranty -- exhaust manifold is included. And, you may also have an open recall on the manifold which allows the dealer to replace it free of charge if it's cracked. (In my opinion, this is the reason it's being sold so far below what most would consider a reasonable market price. Dealers buy from Hyundai and sell back after their allowed markup. Hyundai would like to minimize the markup expense.) -- Message posted using http://www.talkaboutautos.com/group/alt.autos.hyundai/ More information at http://www.talkaboutautos.com/faq.html |
