P1472 A/C Compressor Temperature Sensor Malfunction

As a car owner, it can be frustrating when your vehicle starts to malfunction. One common issue that many drivers face is the P1472 A/C Compressor Temperature Sensor Malfunction. This problem can cause your air conditioning system to stop working, leaving you feeling hot and uncomfortable during your drive. Fortunately, with a little bit of knowledge and some DIY skills, you can fix this issue yourself. In this article, we will provide you with step-by-step instructions on how to fix the P1472 A/C Compressor Temperature Sensor Malfunction.

Step 1: Diagnose the Problem

Before you can fix the issue, you need to diagnose the problem. The P1472 code indicates that there is a malfunction in the A/C compressor temperature sensor. This sensor is responsible for monitoring the temperature of the A/C compressor and sending this information to the engine control module (ECM). If the ECM detects that the temperature is outside of the normal range, it will trigger the P1472 code.

To diagnose the problem, you will need an OBD-II scanner. This tool will allow you to read the diagnostic trouble codes (DTCs) stored in your vehicle’s ECM. Once you have connected the scanner to your car’s OBD-II port, you can retrieve the P1472 code. If this code is present, it confirms that there is a problem with the A/C compressor temperature sensor.

Step 2: Locate the A/C Compressor Temperature Sensor

The next step is to locate the A/C compressor temperature sensor. This sensor is typically located near the A/C compressor, which is usually located on the front of the engine. You may need to consult your vehicle’s owner’s manual or a repair manual to find the exact location of the sensor.

Step 3: Remove the A/C Compressor Temperature Sensor

Once you have located the sensor, you can begin to remove it. Start by disconnecting the electrical connector that is attached to the sensor. This connector may be held in place by a clip or a locking mechanism, so be sure to release it before attempting to remove the sensor.

Next, use a wrench or socket to remove the sensor from its mounting location. Be careful not to damage the sensor or any surrounding components during this process.

Step 4: Install the New A/C Compressor Temperature Sensor

With the old sensor removed, you can now install the new A/C compressor temperature sensor. Start by applying a small amount of thread sealant to the threads of the new sensor. This will help to prevent any leaks from occurring once the sensor is installed.

Next, carefully thread the new sensor into its mounting location. Be sure to tighten it securely, but do not over-tighten it as this can cause damage to the sensor or its mounting location.

Finally, reconnect the electrical connector to the new sensor. Be sure to secure it in place using any clips or locking mechanisms that were present on the old connector.

Step 5: Clear the DTCs

Once you have installed the new A/C compressor temperature sensor, you will need to clear the DTCs from your vehicle’s ECM. This can be done using your OBD-II scanner. Simply select the option to clear the codes, and the scanner will erase the P1472 code from the ECM’s memory.

Step 6: Test the A/C System

With the new sensor installed and the DTCs cleared, you can now test your vehicle’s A/C system. Start the engine and turn on the A/C. Check to see if cold air is coming out of the vents. If everything is working properly, you should feel cool air blowing from the vents.


Fixing the P1472 A/C Compressor Temperature Sensor Malfunction is a relatively simple task that can be done by any DIY enthusiast. By following the steps outlined in this article, you can diagnose the problem, remove the old sensor, install a new one, and clear the DTCs from your vehicle’s ECM. With your A/C system back up and running, you can enjoy a comfortable ride no matter how hot it is outside.


1. Can I drive my car with the P1472 code?

It is not recommended to drive your car with the P1472 code as it can cause damage to your vehicle’s A/C system. It is best to fix the issue as soon as possible to avoid any further damage.

2. How much does it cost to fix the P1472 code?

The cost of fixing the P1472 code can vary depending on the make and model of your vehicle and the cost of the replacement sensor. However, it is generally a relatively inexpensive repair that can be done yourself.

3. What other symptoms can occur with the P1472 code?

In addition to a malfunctioning A/C system, the P1472 code can also cause your vehicle’s engine to run poorly or stall. If you notice any other symptoms, it is important to have your vehicle inspected by a professional mechanic.
