Hi,


I have a 2016 Focus EcoBoost 1.0L and I'm getting a diagnostic code: 

P0131 - O2 Sensor Circuit Low Voltage Bank 1 Sensor 1


I bought what I thought was a replacement sensor on eBay and it didn't fit - there were extra notches on the receiving socket that my eBay sensor didn't match.
The eBay sensor has no notches on the plug, only curves and straight edges
I also noticed, too late, that the original sensor plug and receiving socket have a red/brown shroud.

I think I now know what I need.

There are two pictures below, the first (good) picture is the one i think I want and the second (bad) is what I bought from eBay.

Can anyone confirm that the part I need has one of these numbers:
F1FA9Y460CA      or
1886204          or
0258017467

or give me any advice on making sure I get the right part?

Thanks
