Where to find the outside temperature sensor on my Fabia mk1

[Droculoplastics]

The outside temp. sensor started a few days ago to show --.-c, and i noticed a plug hanging below the car. I need to know where the sensor is to reconnect it. Does this affect any function in the car, like the A/C?

It's located behind the passenger side fog light grille

It doesn't affect anything els to my knowledge either

except the A/C; the A/C won't work if the outside temp is < 5⁰C Not sure how it would affect things if the car doesn't know what the outside temp is :think:

Unplug it and see if it switches off completely then

Ac will work if temp sensor disconnected, my old ibiza does when I had a dodgy sensor

That is weird, I would have thought that broken/open/disconnected sensor would tell the AC outside temperature was below its lower operating limit.

The sensor just displays --.-c but ac will still work, which I admit is strange but at least it still worked lol

Oh well, that is handy at this time of year, might really depend on what the system thinks the temperature is, what you are saying is that O/C = HIGH temperature and S/C = LOW temperature - that is probably true as most "normal" resistive temperature sensors increase their resistance with rising temperature, I stand corrected.

It's an NTC thermistor (just checked, warmer = lower resistance), but I reckon the ECU interprets  (both) extremes of resistance as open-circuit or short-circuit wiring rather than mad temperatures, reports/stores a fault code, and then defaults to using a 'normalish' temperature to let the AC carry on while things are mended?

Thanks all for the info. Actually my A/C works fine, inspite of not knowing what the outside temperature is!
