Fault Code

[Darmon]

Hi Guys,

Code Reader my 172 earlier, and got a fault, i think the code was P0136?

Anyway, checked the book and it said some sort of problem with an oxygen sensor, cleared the code, and its come back.

Could anyone give me any indication at all where the problem may be?

I know I'm being a bit vague, but i'm not too sure of where the problem lies
