Outside Temp Display

[Bourke72]

Hi Guys, can anyone tell me where the sensor is mounted for the Ambient Temp that displayed in the dash on a 2012 D40 Navara 2.5, since washing the engine bay my temp is not working correctly we have a 30 degree day here today and my temp in dash says 20 i was told once its in behind the r/h headlight? any ideas on location? might need to clean out any water in it>

My 2009's sensor is near the vertical bar in the centre of the radiator mount (in front of the radiator). Makes sense to have it in front of the incoming air stream.

Same with my 07

Where can I get one of these...cheap of course.mine is a thai built and was never fitted

Thanks guys

Biggest problem is the dash instrument cluster itself. thats where the brains are for the temp read out. Dont quote me but I think the cluster itself is different between the Spanish and Thai

 

[Old.Tony]

The cluster on the Thai build has the readout, but the entire harness for the sensor is missing.

I have not seen the outside temperature gauge on my dash
Where is it
It's possible I don't have that feature
D40 2008 STX Spanish build

Under the clock

Bugger.such a small thing but i want it

Do you happen to know what type of sensor it is? Possible it's just a k type hidden in a neat plastic case with a nissan logo

 

[Old.Tony]

That's what we suspect but we don't know the exact specs.

Cheers Tony.ill see what I can find out.

I did not get one of those
D40 STX 2008 Spanish build

 

[2007]

My 2007 Spanish STx didn't come with the temp display. However there was another thread, something about "Ambient Temp" in the title. After reading this thread I obtained a sensor from the local stealership. and following the instructions in the thread the display works fine.

I pick up my nav next week, with my line if work it shouldn't be too hard to figure it out, I'll have a play and see what I can sort out then will post the outcome.

The readout doesnt show in the dash until you connect up a sensor
Here is the original thread
http://www.navara.asia/showthread.php?t=72&highlight=show+temp+dash

Inside that thread are links to what we did way back then and part numbers etc and how we came to figure it all out

If its not in there I can find the actual resistance vs temp readings .
We did try various thermo couples but could never find just the right unit for the job.Many tried to do their own thing but at the end of the day we went with Nissan sensors and as far as I know they are all working to this day

AMBIENT AIR TEMPERATURE INDICATION
Combination meter displays ambient air temperature on clock display.
With ignition switch ON, “°C” blinks for a while. Ambient air temperature indication can be selected between
Centigrade and Fahrenheit.
Combination meter reads ambient air temperature signal from ambient sensor.
Signal is supplied

from combination meter terminal 49

through ambient sensor terminals 1 and 2

to combination meter terminal 50.
When a temperature detected by sensor rises, combination meter controls increase of the indicated temperature
depending on engine heat and other effective factors.

If the vehicle speed is more than 20 km/h, the indicated temperature rises according to the vehicle speed.

If the vehicle speed is less than 20 km/h, the indicated temperature is maintained.
When a temperature detected by sensor falls, the temperature is indicated immediately.
NOTE:

The range indicated on the display is between −30 and 60 °C for Centigrade or between −22 and 99 °F for
Fahrenheit.

When the temperature is from −40 °C (−40 °F) to −30°C (−22 °F), “-- °C” is indicated on the display as
over range.

When the temperature is under −40 °C (−40 °F) or over 60 °C (140 °F), nothing is indicated.

When indicated temperature becomes less than 3 °C (37 °F), ambient air temperature indication blinks
warning. After blinking for 20 seconds, only “°C” blinks. At more than 4 C° (39 °F) the display stops blinking.

Self-Diagnosis Mode of Combination Meter GKS0005D
FUNCTION
The following items can be checked during self-diagnosis mode.

Sweep of gauges pointer

Present gauge data values

Odo/trip meter display and clock display segments

Condition of warning lamps/indicator lamps controlled by unified meter control unit

Battery voltage

Driver's seat belt buckle switch status

CPU of unified meter control unit status
OPERATION PROCEDURE
To initiate combination meter self-diagnosis mode, refer to the following procedure.
1. Turn ignition switch ON while pressing clock switch (1).
2. Press and hold clock switch until “tESt” is indicated on odo/trip
meter display (within 7 seconds after the ignition switch ON).
3. Release clock switch when “tESt” is indicated.
4. Combination meter self-diagnosis mode starts.
5. Press clock switch to go to next item.

From the NISSAN MANUAL
Temp vs resistance across terminals 1 and 2 of the ambient temp sensor

Temperature [°C (°F)] Resistance value [kΩ]
(Approx.)

–20 (–4) 15.8 kΩ
–10 (14) 9.60kΩ
0 (32) 6.02kΩ
10 (50) 3.87kΩ
20 (68) 2.55kΩ
30 (86) 1.74kΩ
40 (104) 1.20kΩ

Thanks Aussie Frontier,
Makes an easy start for me, by chance has anyone measured voltage across the sensor?
Will look into it once I've picked up my ute next week , would love to work it out and hopefully nice and cheap
