2010 peugeot , 308 l.6 turbo petrol oxygen sensors

[turbo1600]

does anyone know if the upstream and downstream oxygen sensors will interchange , if i repin the green connector one onto the blue coinnector ?
where i am its easier to get a sensor with green connector , than the blue one.

Depends exactly what you are referring to: There is the gas temperature sensor, the oxygen pollution sensor and then then some models have NOx sensors and they are all different parts - so not interchangeable.

i`m reffering to the oxygen sensors in the exhaust. 02 sensors,

Pop your VIN up for me and I'll see what you have as there are 3 versions of the 308 with multiple 1.6 engine types.

As far as im aware the actual sensors are identical but have different cable lengths & different connectors to stop them getting mixed up, hence the reason they will have different part numbers.
What you are suggesting should in theory work.
