Corsa external temperature - John Foulkes
My '93 Corsa is no longer showing the external temperature on the radio display, it shows --.- ! I found the sensor at the front behind the number plate. It seems to have a dc resistance of about 30 ohms, but it was 70ohms at one point. It does not seem to chnage over even when I put it in the fridge.
I have also measured the voltageon the cable 4.5V so there does at least seem to be some connection back to the display.
Has anyone done similair tests? Do they think I am looking at a new sensor or is it something wrong with the display?
Any help or suggestions for further tests would be gratefully received.

Thanks

John

New sensor normally sorts it

If the resistance doesn't change with temperature, then it's knackered.
