Which Oxygen/Lambda sensor? was created by Osborne

Hi everyone, wonder if someone out there can help me please? We have an orange engine management light on our 52 plate O2. I've just been to my local, friendly mechanic who stuck the OBD reader on it.....apparently it's sensor 1 bank 1! Now I'm guessing this is the manifold sensor as according to the OBD reader there are sensors 1 & 2, logically 1 would be nearest the engine & 2 would be the Cat sensor.....my logic anyway!
So does anybody know for sure so I can purchase the correct one?
Thanks

How many sensors do you have on your car

Number 1 is pre-cat (manifold side), number 2 is post-cat.

If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

That's great thank you. I'll get one on order, so with that sorted & the boot floor welded up she's all done

Why change them as a pair when only one is faulty :huh:
