Outside Temperature

Outside Temperature
In the instrument cluster of a 2005 TSX, there is a display of outside temperature.
This used to display a temperature which appeared to be correct when compared to known temperature for the day.
Some time ago, it started to give readings, which in hot weather, were clearly about 6 degrees (F) above actual temperature, so it can no longer be relied on as an accurate indication of temperature. Although it took a while realise it was inaccurate, there is a possibility that the changed happened after the car had been in the garage.
Is there something that could have become disconnected or is there a simple method to calibrate the gauge so we once more have an accurate reading.

You need to check calibration of Outside Air Temp sensor w/ a Volt-Ohm Meter (VOM). Resistance at 0 C (32F) in ice water should be about 6.25Kohms. At 20C (68F) should be about 2.5Kohms. If too far off, it should be replaced. There is no calibration procedure mentioned.
Or you could just replace the sensor. It's on back side of front bumper beam.
good luck

Thanks for your replies to this. The user manual is the last place I would have looked, I find it unusual to have that sort of information these days.
I will try the adjustments when I can get what I believe to be a condition where I have a good idea of the temperature.
