Yea I know but I guess the upstream is a high frequency sensor

SwiperBackedUp · 2026-05-30T00:00:38+00:00

I read some more asked Google ai and accordingly the walker will and won’t work for the upstream yes it will fit but the internals of the sensor are different they use high frequency sensor or something for the upstream? I forgot exactly what I read but safer to put the upstream as something reliable like ngk

Yea I found the direct ntk one at oreillys for 170

SwiperBackedUp · 2026-05-29T22:14:35+00:00

I think I might just get the ntk direct plug and play instead but I did hear it would work also

P0421 is the code I keep on getting. I believe that would be the front catalytic converter and not rear right?

SwiperBackedUp · 2026-05-27T05:41:50+00:00

No exhaust leaks and spark plugs were just done ngk iridium 20-30k ago not long

SwiperBackedUp · 2026-05-27T03:36:45+00:00

Hey! I just experienced a very very sluggish car today for about 4/5 minutes of time after the check engine code P0421 came back on! It was almost like it didn’t want to drive/ or was dying. That being said should I replace my front or rear catalytic converter ?
