Cel

[T4R03]

Probably drove the last 15-20k miles with the CEL on. Same codes every time. All started after stomping on the gas. CEL came on right away after a pull. Seems like when I clear the codes P0430 is the first one to pop up. Then after driving after a while It’s followed with P2241, P2238, and p0332. (P0430 is catalyst efficiency code and it’s Followed up by two O2 sensor codes and a Air/Fuel ratio code and a knock sensor after driving). I want to say these are related but I don’t want to change all 4 sensors if I don’t need to. That’s expensive lol. Will do it if I absolutely have to. Just want to know if anyone has had these codes before and what they did to fix it. I’m hearing changing 02 sensors but people have done this and codes come back. What are your thoughts?

I get the p0430 on occasion too, usually after a highway run. There's been some who've solved it by repairing leaks in their exhaust system, mainly the one where the pipes come together from each side. As for the other codes, can't say that I've heard of the extras popping up. I certainly wouldn't shotgun all the o2 sensors. The p0430 I believe is the driver's side.
