outside air temp sensor

[james walker]

can anyone confirm if this has any effects on anything other than the dash reading of outside temps?


had a quick look but not much in the way of info on this one.

Also ties into the climatronic.

 

[james walker]

and what affect would the sensor not working have on the climatronic?

cheers

If its telling the car its below 5 degrees then the compressor won't work to save it freezing

 

[james walker]

just simply for climatronic, no affect on engine wise?

Not 100% sure TBH.
I would imagine its send some sort of signal through the ECU but what it does with the info I dunno

Outside air temperature sensor has no connection to the ECU. It is solely for your own amusement.

The ECU gets the charge temperature from the inlet air temperature sensor, which is in the inlet trunking after the intercooler.

The Climatronic has a sensor on the inlet side of the cabin air blower, which tells it the inlet temperature. There are three temperature sensors in the cabin that are used by the Climatronic to decide whether to blow hot or cold and where to do it.

The only influence that outside air temperature has on the cabin air system is that the cooling compressor will shut down if it gets below 3° or so, but I don't know if it gets this from the blower inlet or the outside temperature sensor.

I should see a doctor if I were you . . .

Oh, you mean the outside temperature sensor on your Mk.1 LC has gone mad?

What symptoms is it showing? Low, high, random readings, no reading at all?

It's in the front bumper, somewhere close to the nearside fog light. A small plastic sensor with a rounded end, clips into a round hole. In the standard bumper it looks like this:

Now, what brought that on? At least I don't end every sentence with a bang!

i cant believe iv never seen it on the bumper, canrt see for looking thankssssssssssssssssssssssss.

 

[cupra monster]

where is the outside temp on a mk2???????????

 

[Muttley]

From what I can tell just looking at diagrams, it's in roughly the same location i.e. offside front bumper near to the foglight. It seems to be mounted behind the grill, so I assume the Mk.2 foglight grills allow air to flow through, unlike most of the Mk.1's.

On an LCR It's behind the NSF grill beside the fog light.

sorry to re open an old thread but i was 99% sure i seen on here people had reaced the outside air temp sensor which was located in the passenger wing mirror?? :s and can anyone give me the part no. for the sensor if you have it handy? cant find it anywhere

 

[Willie]

The Ibiza Cupra one is under the near side wing mirror, 100% the LCR one is on the near side front fog grill

 

[LEE69]

LC one is there Willie

 

[Muttley]

Ibiza's are based on the Polo, and I guess the Polo puts the sensor in the mirror.

Leon's are based on the Golf, and they all have the outside air temperature sensor in the front bumper, close to the nearside foglight position.
