Long shot, but..
I have a fault with HO2S Heater Control Circuit - Bank 1, Sensor 1 (from diagnostics), but I don't know which of the two pre-cat sensors is which.
Conflicting info on the web and I don't want to get the wrong one.
It should show this in the Haynes manual, but I've only got a manual for my old Mk1 Focus and the engine is different.
Anyone shed any light..?
