What does ambient air temp sensor do?
What does ambient air temp sensor do?
Thermometrics Ambient Air Temperature Sensor measures the temperature outside the passenger compartment and is usually mounted inside or near the front bumper. The sensor provides input to automatic HVAC systems to help control the interior temperature of the automobile.
What is the ambient air temperature sensor on a Chevy Tahoe?
The ambient air temperature sensor is a variable resistor interfaced to the Body Control Module (BCM). 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.
What’s the outside air temp on my Chevy?
I repaired the broken wire, and installed the new sensor, and now the temperature display reads a constant minus 16 degrees. I checked the connector and I have 5V DC, so there is power.
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.
Where is the oat sensor on a Chevy?
The sensor is located in the small hole in the left (drivers side) fog lamp filler in the front bumper cover. You must remove the lowest horizontal cover to see up at the back of the sensor……it just snaps into the housing. There is a two wire connector that plugs into the sensor.

Where is the outside temp sensor on a Chevy Raditor?
Part# – ACDelco-25775833. You might also want to check your local Chevy dealer for the part number, just to be sure. Re: Location of outside temp sensor? Outside temp sensor is on the hood latch support in front of raditor about dead center. If you have a plow on the front it will disrupt the air flow and likely cause the temp to rise.
How often does the outside temp sensor change?
If the vehicle has been off long enough (cold or cool condition) and/or the ambient outside temperature has decreased, a new exterior temperature should be displayed. The outside air temperature will continue to be updated every second as long as the outside air temperature is the same or cooler than the previous reading.
