    Hi guys I have by accident mixed up the sensors on the top of the manifolds of my 612.The cables are all the same length and the engraved Bosch numbers are the same.Are these interchangeable although the Ferrari part no is different between front and rear manifolds?
    Thanks

    The lambda sensors are the same for the front and rear manifolds. The fact that they have the same bosch number is confirmation of this. The only reason that the Ferrari number would be different would be different cable lengths, or the blue color on the front sensor.

    They need to be correctly connected, otherwise the engine ECU will receive erroneous info

    Thanks quys i have corrected the connections and the car is running and idling as it should.
    This was a breath of fresh air after a plethora of events including replacement of inlet gasket a damaged L/H rear manifold and last but not least a leaking water pump.
    Thanks for your valuable response.
