How does the ambient temperature sensor work in a car?
It is the job of the ambient temperature sensor to measure the external temperature of the vehicle as a reference point for the computer to make calculations. The computer will continuously monitor the signal from the ambient temperature sensor and make automatic adjustments as needed to maintain cabin temperature.
What are the signs of a bad temperature sensor?
Common signs include a faulty AC auto mode, inconsistent cooling, and incorrect outdoor temperature readings. 1. The AC auto mode will not work 2. Inconsistent cooling 3. Incorrect reading on temperature gauge
What kind of emissions does a Honda Civic have?
3 Trims are LEV3-SULEV30-rated in California and states that have adopted California vehicle emission regulations. Trims in non-CARB states are LEV3-ULEV125-rated.
When do I need to replace my ambient temperature sensor?
If the reading on the gauge or indicator is off by more than a few degrees, then the sensor should be replaced, as the incorrect reading may interfere with proper AC system functions. The ambient temperature sensor plays an important role in the overall operation of the AC system.
Where is the outside air temperature gauge located?
Description The outside temperature sensor is located behind the center of the front bumper. The gauge control module (tach) uses measurements from this sensor to display the outside air temperature.
What should the outside air temp be when turning on the ignition?
If the engine coolant temperature is 59 °C (139 °F) or lower when the ignition switch is turned ON (II), the current temperature measured by the outside air temperature sensor will be indicated. Update to the outside air temperature indicator while driving
What should the outside air temperature be on a car?
If the engine coolant temperature is 60 °C (140 °F) or higher when the ignition switch is turned ON (II), the outside air temperature indicated the last time the key was turned off will be displayed regardless of the current temperature measured by the outside air temperature sensor.

What to do if your ambient temperature sensor is not working?
1. The AC auto mode will not work Most modern vehicles have an auto AC setting that will allow the vehicle to automatically set and regulate the temperature. The AC system will simply read the ambient and cabin temperature sensors data and continuously cycle the AC system on and off as required to keep the cabin cool.
Can a temperature sensor on the outside affect the HVAC?
No, the outside temperature sensor should not affect the HVAC. That sensor is only there to give you the outside temperature reading on your dash. Modern climate control systems use temperature sensor (s) inside the car to control the temperature.
What is the purpose of an external temperature sensor?
In an automotive HVAC system, the sole purposes of the external temperature sensor are: 1)to allow an ATC (automatic temperature control) system to automatically evaluate a comfortable internal temperature setpoint without any operator intervention.
