    Hi Graham, Did you find out anymore info on this system, I have just seen a Transporter with the same engine code and the same problem as yours.
    The wiring shows an air temp sensor and co adjuster in the the same component but there is no pin data as to what voltages to expect.
    This is mounted in the air inlet trunking.
    With a three wire component such as this I would normally expect to see a live feed, an earth and an output but I dont know how this works in with the air temp bit.
    Does anyone know what voltages to expect as all I can see from this device are negative voltages.
    CH.
