Cat sensors for 1.2 clio

[Louis]

Are the sensors both the same post and precat on the clio 1.2? I have an engine management light I believe to be the cat sensors. Which do i need?
Thanks

Yes both the same.

get it plugged in before you start replacing stuff

It's getting plugged in tomorrow but i wanted some lamda sensors just in case, can always send them back if this isn't the problem! Hopefully it is though as it just had a new cat as the old one split in two and this probably put some strain onto the sensors.

Got it on diagnostics and it was a lambda sensor. Removed them both and replaced with the new however the post and pre sensor which came off the cat were different. But the ones that were put on were the same...
Will this be an issue?

they should be replaced for the same ones, there are two different types, computer may adjust but im not sure

Well the engine management light has returned so i'm guessing that it was wrong that they were "both the same". Will put the old one back on post cat, and see if this makes any difference. Will the light go off if it can adjust itself or do I need to get it on diagnostics again?...
