    Vectra C temperature sensor

    My outside temp is reading -30 or something stupid.

    Will this be the outside temp sensor?
    Where are they on the Vectra C?
    Is it possible to test them? I know they are only a fiver on flea bay but if it aint broke....

    Cheers for the reply. So can you fix them or test them?

    Or will I just need to get a new part?

    to be honest i have never tried testing them as its always been the sensor, and they are a sealed unit so very doubtful its repairable, best of putting a new 1 in mate

    Had it in the shop, fault code showed sensor circuit.
    Replaced sensor.
    **** all.

    So what else can it be? A short? HEEEEEEEEEEELLLLLLLLP!

    It cost me £60 for the diagnosis, £2.50 for the sensor, and I'm no better for it.

    £2.50 for the sensor, thats cheap, ours r about £15!!! errrm, only thing left is the wiring to the sensor its self, shouldn't be too hard to trace back as there's only 2 wires.
    theres bound to be a fuse 4 it, has that been checked?

    Not sure...

    Is it easy to change the wiring to the sensor?

    I assume fuse is OK because there is 'a' reading.

    Today, however, it did say
    c
    F

    Where it would usually have a number.

    it won't be the LCD display that's broke, would it?
    Note: the above may or may not be entirely correct.
    I wondered why the frisbee was getting bigger, and then it struck me.

    No, it shouldn't be, its working fine in all other areas, today it was back to minus 35 degrees. Should I get another new sensor and replace the wiring on it?

    Thoughts?

    i reckon youve got some dodgy wiring mate. these sensors work on varying resistance to give you a reading. a dodgy connection or even a dodgy earth could be messing the resistivity of the circuit. if you know how to use a multimeter get busy!!
