P0156 fault code query

Hi guys,

 

so ive very recently bought my 1.6 petrol focus 05 reg.

 

an engine management light came on and I've hooked it up to a obd2 reader that throws out fault code P0156. A quick lookup shows this to be a faulty sensor on bank 2 sensor 2. I'm led to believe this is the o2 sensor.

the thing I'm confused about is that surely being a 4 pot it only has one bank? Does anyone have an exhaust diagram of where this would be and a part number?

 

any help is massively appreciated

There are two O2 sensors in the system and if I remember right sensor two is the 'post-cat'. (Someone will correct me if I'm wrong)

Yea I did think so but only one bank surely? 

 

So of the two which does it relate to? Post cat? I need to get a Haynes manual really

Give me 5 minutes and I'll photograph the Haynes page
