Temperature Sensor
My outdoor temperature sensor reads a constant 50 deg. I'm in So Cal and I know its warmer than 50 deg outside. My friends VW was reading 68 yesterday while I wa still at 50.
The only mod I have made is an inviscord for my radar dector. Caould this have efected the sensor? Has any one else had a bad temperature sensor?

If the outside temperature goes up the reading won't change until you either keep the cars speed above 12 miles per hour for 5 minutes or 32 miles per hour for 2 1/2 minutes.
Try taking it for a ride and see what happens.

There is also a sensor located behind the front
bumper. This sensor reads the outside air
temperature and helps to maintain the temperature
inside the vehicle. Any cover on the front of the
vehicle could give a false reading in the
temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
• The vehicle’s speed is above 12 mph (19 km/h)
for five minutes.
• The vehicle’s speed is above 32 mph (52 km/h)
for two and a half minutes.
These delays prevent false readings. If the
temperature goes down, the outside temperature
will be shown when you start the vehicle. If it
has been turned off for less than three hours, the
temperature will be recalled from the previous
vehicle operation.

IT'S STILL DISPLAYING A FALSE READING!
Waiting to see if it's correct does not prevent it from being wrong. Only turning the display off would prevent it from displaying a false reading.
Reminds me of the old riddle...
Q: Which clock is more accurate, one that is only 1 second slow every month, or a broken clock?
A: The broken clock. Because it's EXACTLY right twice a day.

It does not prevent a false reading per se; it avoids the issue that plagued ealy systems. If you stopped at a light in an early 90s GM car, the temperature reading would climb to whatever the underhood or street temperature was. Then you'd drive for a half mile, and it would read about right. Then you'd stop and the whole thing would repeat. You never actually knew what the temp was unless you drove at a steady speed for some time anyway.
With the way it works now, if the temp is lower than it was in the garage (common when the car has been parked inside in cold weather), the reading will go to the acurate temp quickly. It doesn't go up quickly to avoid the issue mentioned above.

several have reported this problem. i read they replace a sensor and problem is fixed. mine today read 43 degrees when it had to be low 70's all the way home 27miles. havent had mine fixed yet. but have asked for it to be address several times. it is just low on priority. my 03 silverado had no problem reading correct temp
