O2 sensor?
Hi. I have 2011 Citroen relay 2.2 120. Where is an oxygen sensor? Not on cat. Dont even see a wiring for it. How does it see fuel trims?

Re: O2 sensor?
Would a diesel engine even have an oxygen sensor? Why do you think it would have one?

Thats actually a good question and i feel a bit stupid now but i worked on few bmw and i remember them having a sensor on cat. So how does a computer know if an injector isn't pouring loads of fuel?

Just realised everything. Newbie... had a decent brain fart. All this isolation probably. Anyway thanks for you help to make me think again.
