P1166 & P1167 after changing exhaust

[martinj46]

As the title suggests, I've swapped my mid pipe over to a Spoon piece this afternoon, and with it fitted the above codes are displayed. I've searched them and it seems to be for the primary 02 sensor. Nothing was touched on either of the sensors though. Any ideas? Could removing the studs on the flange to replace with new ones have someone damaged it? And how much are new sensors from the dealer?

Cheers

Had no problem when changing mine from 5Zigen to Spoon. Could be coincidence. How old and mileage is yours? Quite common to go.

It's a 51 plate sat at around 75k

New sensors are going to be expensive... I read a thread saying integrastella sells them for £130 second hand

Bite the bullet and buy new..

Iirc it was that much fitted at Honda! Get a quote first though. I could be wrong. See if you can talk to an engineer there too about the code.

Mileage and age seem about right when mine went. It's expensive but has to be done. Pitfall of a DC5.

I don't have a problem paying for it, just thought I'd check if there was anything else I should be checking first?

Check the connector, to get both codes is a rarity.

If they are still there once you have checked it, reset the ECU to see if they clear.

If not, as above, genuine sensors only.

Cheers Stoo. I'll crawl under again tomorrow

I know this is a stupid question, but thought I'd best ask before I rule it out... If the cat had decided to give up, it would be the secondary sensor that would flag up a fault, correct?

 

[Stoo]

Yes

I had the same codes and replace my primary O2 sensor genuine Honda one I payed about£198 lights off now and the car feels better for it

Thread revival:
So just to confirm, codes; 1166,1167 and 0141 can all be fixed by replacing only one part (the rear/2nd o2 sensor?).

I cleared the codes, drove home from work and they all came back Bye bye £200 I think?

 

[martinj46]

Changing the primary sensor fixed it for me. £170ish from tegiwa or Honda iirc
