Sup all,

I have a 2000 se and i had cel light. p0430 and p 0420. Bad part is my inspection had just expired on my car and u cant pass if you cel light is on. So i pulled the code and it was the p0430 p0420. so i was screwed !! month goes by still no inspection and cel is bright as ever. Then , parked in the city I find out my car was side swiped. Just a lil cosmetic damage but still i took it to the auto shop and was getting fixed. While in the shop the shop told me i needed a new battery so i said go for it.. (insurance covered it all) to make a long story short. After the battery was replaced the light went out.. I thought it would come back on .. But it never did so i took my car got it inspected and everything is Great~!!! has this ever happened to anybody ???? so all u people with p0430 and p0420 codes change your batteries and it might actually fix the issue.....

 

Those codes have nothing to do with the battery from my search, I wouldn't be surprised if the CEL comes back on. Also, why didn't you just fix it in the month that passed?

 

things came up and i wasnt even paying any attention to inspection.. I thought so too but im crossing my fingers so hopefully it wont come back but if it does ill get a o2 sim .

 

the CEL will definitely come back on. Believe me when it does it will be worse. Just prepare to change the Cat and precat or Do what Im planning, Get a high flow CAT and a Ypipe

 

Swapping the battery probably just reset the ECU therefore clearing the codes. They will probably come back.

 

Like already said, the battery being disconnected is what cleared the codes; it has nothing to do with it being replaced. If your pre-cats are bad, the CEL will come back later, if not, then it was one of those "ghost" codes that people talk about.
