R34 Gt-T Outside Air Temperature Sensor

[Shoujiki]

Hey guys,

So i'm installing some new horns in my car, and I have this sensor down near the bottom of the A/C radiator. In re-routing the wires for horns, i'm wondering, do I require this sensor to be plug in? Can I remove it and leave the plug cable toed up nicely somewhere?

I was told that it displays the outside air temp on the HVAC display if you press the knob in, however mine doesn't push in (series 1?). I've read that if the HVAC system doesn't see the sensor, it'll think it's freezing cold outside and run the heater all the time.

Thanks

i wasn't aware that the series 1 had outside temp sensor, or else i'm just wrong.

Confused me too! Since people suggested it was the models that had the HVAC controls button feature that shows outside temp, that had the sensor.

And this is strange also. Turn the A/C on, set temperature to 18c. Blows icy cold air. Set to 18.5c blows warm air.

This happens whether the sensor is plugged in or not.

Bit of a search! Found this: http://www.skylinesa...higher-then-18/

Will check that sensor as i've had the dash panel off.

EDIT: Yep, it was that sensor in the dash unplugged! Awesome!

But...

Still can't find anything else about this outside air temp sensor though!

If you invert and spin one of the horns slightly they bolt up fine ( super tight but works)

So the blitz Fmic bolts up fine

The sensor need to be there it feeds info into the ecu according to shop manual

Mine just shut my ac off automatically when the car was sitting too long in 40c+ heat but its still between Fmic and radiator heat soaking , needs moved in front of Fmic to work properly when the car has no airflow

the ecu has a fails safe that shuts off the ac at extreme temps and won't allow it to come on again till it senses cooler air( that is on auto mode)

Thanks mate, confirms it for me then. I'll just leave it plugged in, but i may attempt to relocate it in front of the FMIC or to the side somewhere where there is more direct airflow.

Yeah one of my horns is cactus, very strange sound it makes. So i just got some replacements!

Thanks again! I learnt a lot (AC diagnostics) and fixed a separate issue because of this!
