Technical Fiat Barchetta Lambda Probe Oxygen sensor DIY guide

I need to ammend & update my earlier guide. I have reviewed the wiring info within the FIAT user manuals again and found that I got the lambda connections wrong in the picture within the guide that I posted before. I have attached the correction with a little more detail and will help with aftermarket third party replacements.
Hope it helps.

So that's why my Barchetta stopped running properly!

<only joking :D>

Haha!
In all seriousness though, if you had the signal wires from the lamda sensor crossed (as per the earlier picture within the guide) then your engine will have probably been running a little rich and your emissions tests will have been a little on the high side.
