hiya guys,
i have had this problem for a while now but it has started to annoy me.

earlyer this year the outside temperature sensor just decided to display "F" on the display.
staight away i thought it would be the sensor had gone faulty,,so i bought a new one from vauxhall and changed it,,,alas the fault was still there.
after the car has been sitting for some time when the door is unlocked it will show --.-oC then go off (i presume this is resetting itself) and then F will show on the display.

please help,,it is anoying me now !
many thanks
Roy
my car is a 52 2.2 dti elite

cheers

It reads like he already has done.

I had this recently with excessive use of the TC in the snow, but a ignition switch off and on sorted it and its been fine since.

I had this recently until i remembered i had not reconnected the cable lead on the bumper .
so i would check out your connection,s.

cheers for the replys.
i checked out the sensor again and the wiring to it, i cant see anything wrong at the sensor or plug.
is there any other plugs it could have come un-plugged from ?
do you know if it is fused or goes straight to the ecu ?

thanks for your help again
Roy

Just below and behind the front number plate.

temp sensor wires go to pins 44 and 47 of the body control module.
Behind the glove box.
Shoud be blue and blue/white wires.

other than this there is a can-bus wire from the body control module pin 40 (green) to the display...pin 28

If it's not the wiring, then it would be either a dodgey display or a dodgey bcm
