Generally, the outside temperature sensor is located under the front of the hood near the bottom of the car. Although the sensor itself is accurate, the location causes the sensor to pick up heat from the road surface.

Why is my car reading the wrong outside temperature?
Most cars these days have 2 sensors: one inside and one outside. The sensor that measures outside temperature is typically up behind the bumper, which is near the hot asphalt and the engine. That’s why it reads a little higher that what the temperature actually is outside.
How do I know if my ambient temperature sensor is bad?
What Are the Signs of a Bad Ambient Temperature Sensor?
- Your Car’s Auto AC Setting Doesn’t Work.
- Your Car’s AC System Cools Your Car Inconsistently.
- Your Car’s Outside Temperature Gauge Is Incorrect.
How many temperature sensors are in a car?
There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard. The device follows the principle of dependence of potential difference in temperature.
Where is the ambient air sensor located?
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.
Can you bypass an ambient temperature sensor?
Can you bypass ambient temperature sensor? As far as the ambient sensor, that is not the MFA ambient temp sensor. This is for the A/C to make sure the compressor does not turn on on if the Sun Load is above a certain threshold to protect the compressor. This one, you can bypass if you wish.
How accurate are car outside temperature readings?
Therefore, if a car is parked on asphalt or concrete, the temperature you read is much warmer than what you will see if parked over a grassy or shaded surface. According to the Lawn Institute, “temperatures over turfed surfaces on a sunny summer day will be 10-14 degrees cooler than over concrete or asphalt.”
What will a bad air temp sensor do?
One of the first symptoms that a vehicle will display when the air charge temperature sensor has failed is a noticeable reduction in power when accelerating. A bad or failing sensor will not send the correct signal to the computer which will negatively affect the computer’s air / fuel mixture calculations.
How much does it cost to replace an ambient air temperature sensor?
Ambient Air Temperature Sensor Replacement Cost – RepairPal Estimate. Labor costs are estimated between $51 and $65 while parts are priced between $34 and $38. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
Does temperature sensor affect AC?
As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem this may interfere with the system’s ability to cool the vehicle.
