Where is the temperature sensor on a Honda Fit AC?
The temperature sensor on a Honda Fit's air conditioning (AC) system is typically located near the compressor or the condenser. This sensor plays a crucial role in regulating the temperature of the air being circulated through the vehicle's cabin.
Understanding the Role of the Temperature Sensor
The temperature sensor in a Honda Fit's AC system is responsible for monitoring the temperature of the refrigerant as it flows through the system. This information is then relayed to the vehicle's computer, which uses it to adjust the compressor's operation and ensure the desired cabin temperature is maintained.
By continuously monitoring the refrigerant temperature, the sensor helps the AC system maintain the optimal balance between cooling power and energy efficiency. This ensures the cabin remains comfortable while minimizing the strain on the vehicle's electrical system.
Locating the Temperature Sensor
The temperature sensor on a Honda Fit's AC system is typically located in one of the following areas:
- Near the Compressor: The compressor is the heart of the AC system, responsible for circulating the refrigerant. The temperature sensor is often mounted near the compressor to monitor the refrigerant temperature as it enters and exits the compressor.
- Near the Condenser: The condenser is the component that converts the refrigerant from a gas to a liquid, releasing heat in the process. The temperature sensor may be positioned near the condenser to measure the temperature of the refrigerant as it passes through this critical component.
The exact location of the temperature sensor can vary depending on the specific model year and trim level of the Honda Fit. It's important to consult the vehicle's service manual or a qualified technician to determine the precise location of the sensor on your particular Fit model.
Importance of the Temperature Sensor
The temperature sensor plays a vital role in the proper functioning of the Honda Fit's AC system. By continuously monitoring the refrigerant temperature, the sensor ensures the system operates at peak efficiency, maintaining the desired cabin temperature while minimizing energy consumption and wear on the components.
If the temperature sensor malfunctions or is not properly calibrated, it can lead to issues such as inconsistent cooling, reduced efficiency, and even potential damage to the AC system. Regular maintenance and inspection of the temperature sensor, as recommended by the manufacturer, can help ensure the longevity and optimal performance of the Honda Fit's air conditioning system.
How do I know if my AC temperature sensor is bad?
Symptoms of a bad AC temperature sensor include inconsistent and fluctuating room temperatures, frequent short-cycling (turning on and off too often), or the AC running constantly. Other signs are higher energy bills, unresponsive remote/thermostat controls, and error codes on digital displays.
Performance and comfort issues
- Inconsistent temperatures: The air conditioning can't maintain a set temperature, leading to hot and cold spots or air that fluctuates between warm and cool.
- Frequent on/off cycling: The system turns on and off much more often than it should, which is also known as "short cycling" and can strain components.
- Continuous operation: The AC runs constantly without ever shutting off.
- Unusual noises: Strange sounds like clicking or buzzing can indicate a sensor problem, though they can also signal other issues.
Electrical and cost-related issues
- High energy bills: The system works inefficiently, leading to a sudden increase in your electricity bill.
- Unresponsive controls: The thermostat or remote may not seem to work correctly, or the system may not respond as expected when you adjust settings.
- Error codes: Modern AC systems may display an error code that specifically points to a sensor issue.

Or 20,000 ohm position next place the two test probes on the two electrical contacts. It doesn't matter which color test probe goes on which. Side.
Where is the AC temperature sensor located?
The AC temperature sensor is typically located inside the indoor AC unit, near the evaporator coil. For in-car systems, it's often on the passenger side of the evaporator box, underneath the dashboard. For a home system, it will be located where air is drawn in before passing over the coils to be cooled.

In a home AC unit
- Location: Inside the main indoor unit, the sensor is attached to the evaporator coil.
- Function: It's placed so it can measure the temperature of the air after it passes over the evaporator coils, which helps the system regulate the temperature to your desired setting.
In a car AC system
- Location: Under the dashboard, usually near or on the evaporator box, often on the passenger side.
- Access: You may need to remove a dash panel or a component like the glove box to get to it.
- Function: It monitors the air temperature inside the cabin to control the compressor and maintain the desired temperature, as well as to prevent the evaporator from freezing over.
Why is my Honda Fit AC not getting cold?
The most common reasons a Honda Fit AC isn't working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.
