2.5 Duratec O2/lambda sensors question.
 

Well I have a Cougar V6 and have read in different places it has either 3 or 4 oxygen sensors. Can anyone confirm how many it actually has? Also, whatever number it has, are they all the same part number or do they differ?

Thanks!

Anyone? Google doesn't seem to be revealing much

My ST24 had 3 but in was a R reg so was a early one I think 1999 on had 4 if you get stuck let me know what year it is and can check a wiring diagram at work tomoz! I'm sure the downstream ones will be different from the upstream tho

it has 2 narrow and wideband bank 1 and bank 2

Wideband on a Ford :shocked:

Hi guys, thanks for your input. Really doesnt seem to be a definitive answer on this anywhere lol.

The car is 2000 John, thank you very much, appreciate your help!

Someone I spoke to today confirmed what Jay said, it has 1 on each bank. Not sure if those are the only 2 though. Inclined to think they might be

I checked the wiring diagrams we have mate only lists 2, one for each bank

Thanks very much John, appreciate you going to that effort! 2 it is then, will work out cheaper than 3 or 4!
