How long does it take to update the outside temp on my dash?

How long does it take to update the outside temp on my dash?

Update time will appear to be delayed and could take longer than one hour depending on driving conditions. A vehicle speed in excess of 32 kph (20mph) for three consecutive minutes is presently required for an update to occur.

When does the outside air temp change?

Once the new outside air temperature reading exceeds the previous temperature and the vehicle is traveling less than 18 mph (29 km/h), the displayed outside air temperature will remain at its last value. Once the vehicle speed exceeds 18 mph, the displayed outside air temperature will be updated.

How does the outside air temperature sensor work?

The BCM provides the logic for reading the ambient air temperature sensor, filtering the data and transmitting the information via the serial data circuit to the outside temperature display. The outside air temperature algorithm uses three pieces of information: outside air temperature data, vehicle speed, and the time the engine was turned off.

Why does the outside temp on my car vary?

If you’ve ever looked at your car’s outside temperature display while idling in traffic on a nice summer day, you’ve probably noticed the display can vary quite a bit from reality. As Lifehacker explains, that’s because the sensor telling your car’s computer the temperature might not be in the best spot.
