    On the exhaust Royce, just behind the catalytic converter.

    Looks a bit like a spark plug thread into the exhaust with a plug and wires on it. (Assuming you actually have an O2 sensor - only one of mine do.)


    Trust you are travelling OK......long time no see buddy! ;)

    Okay, I found both my caravelles are still running connected O2 sensors. The manual has been running a bit rough and idling fast for a while now. I disconnected the sensor and she is running much stronger and idling slower. Is this expected or am I just getting carried away?? It made virtually no difference around town in the auto but she was running perfectly before I disconnected hers. Cheers

    It’s just a fine tuning adjustment to the ECU when they are working. If they fail, they send a bad signal to the ECU, and therefore will run better unplugged.

    As I said, only one of mine has a connected O2 sensor. ;)
