Troubleshooting Ford Fusion Tire Pressure Sensor Fault!

Firstly, if your tire pressure is below the recommended PSI, this issue may occur. Secondly, a malfunctioning TPM sensor causes the tire pressure fault for the Ford Fusion. Finally, any interruptions relating to radio frequency disrupt the workflow of the tire pressure sensors of the Ford Fusion.

This is only the tip of the iceberg. To know the reasons and fixes in-depth, read the article till the end and fix the ford fusion tire pressure sensor fault

Key Takeaways

  • Tire pressure getting low is common and the easiest solution for this is to inflate the tires back up.
  • Frequency scanners can be used to both detect and train the TPMS sensors.
  • Any external frequency can mess up the internal system of a car and cause a ‘tire pressure sensor fault’.

Ford Fusion Tire Pressure Sensor Fault: Quick Fixes

The first step in solving the tire pressure sensor fault of the Ford Fusion is to find the correct reason. This issue may arise for more than one reason. These reasons are also applicable to other models of Ford, like the Ford Escape tire pressure sensor issues.

In the table below, all the possible reasons and solution behind the tire pressure sensor fault is mentioned, have a look.

Ford Fusion Tire Pressure Sensor Fault: Detailed Solution

Here are all the common reasons for the Ford Fusion Tire Pressure sensor fault with a detailed troubleshooting guide-

Reason 1: Malfunctioning TPMS

The Ford’s tire pressure sensor fault is a common aftermath of the Tire Pressure Monitoring System malfunction. This can be annoying since the sensor will send out incorrect signals even if the tire pressure is within the acceptable PSI range.

The issue may happen if your tires have recently been replaced. The new tires raise a calibration issue, which typically requires a reset. Another factor could be that your spare tires aren’t the same size as your original tires. 

The size imbalance throws the TPMS sensors off. For instance, if you’re driving a Toyota Tacoma with a 3-inch lift and 33 tires, spare tires that are small can raise TPMS faults.

Solution 1 of 2: Reset and Replace the Sensors

To counter a malfunctioning TPM sensor, you’ll have to reset the sensors. It’s also known as training the wheels. To reset the sensors-

  • Start by putting the key to the ignition lock, and push and release the brake pedal once.
  • Then, turn the key to ‘on’ and ‘off’ position 3 times. Leave it in the run position and push and release the brake pedal again.
  • Next, turn the key to ‘off’, and then turn the key to ‘on’ and ‘off’ 3 times again. At this point, you should hear a beeping sound, which indicates that you’re in tire train mode. The dashboard should also show ‘Train Left Front Tire’.
  • After that, use an OBD2 scanner. Select ‘Ford Fusion’ from the main menu. Then, select the year as well.
  • Afterward, go outside of your car. Start by scanning the front left tire. Place the scanner really close to the tire and press ‘scan’.

    The horn of the car should honk abruptly once, to indicate that the tire is done training. You can also check the battery status with the scanner.
  • Finally, repeat this process for all the other tires. The sequence should be front left -> front right -> rear right -> rear left. After training all 4 tires, the dashboard should show ‘Training Complete’. If that’s not the case, train all 4 tires again.

You can use this video as a guideline for resetting the sensors on your Ford Fusion-

If resetting the sensors is not getting rid of the issue, then the sensors need further inspection. To find out which sensors are defective, use the OBD2 scanner. You can also find it from your dashboard, taking the model into consideration.

After that, swap out the defective TPMS sensors with new ones. The new TPMS sensors can cost anywhere from 50$ to 100$. The battery of the TPMS sensors lasts around 3 to 11 years, so you can avoid frequently changing them.

You will need to reset all the sensors after the new sensors are put into place. This lets the car system know that new sensors are in place and the calibration is done right. 

Without resetting, the new and perfect sensors still may send false ciphers to the system.

Solution 2 of 2: Test and Replace the Car Battery

This solution is quite straightforward. To execute this solution, use a multimeter on your car battery to get a reading on it. If the voltage output is close to 10.5 or less than that, the battery is in bad shape. A replacement would be a great option in this case.

To replace the car battery-

  • First, locate the car battery on the front part of the car.
  • Then, disconnect the terminals and clean the battery tray and terminals thoroughly.
  • Finally, place the new car battery inside and reconnect the terminals (both positive and negative) properly.

A new battery will keep the overall system of your car smooth and the tire pressure sensor fault should be gone.

Reason 2: Low Tire Pressure 

The tire pressure fault light on your Ford Fusion is almost always caused by this. There are four sensors altogether on Ford cars, one on each tire. The ‘tire pressure sensor fault ‘ will come up on the dashboard whenever the tire’s pressure is incorrect.

A deflated tire is a sign that a tire’s pressure is incorrect. These can lead to decreased fuel efficiency and acceleration, risks of blowouts, etc. Also, you may notice the balance of your car is not right and the car might be drifting in a biased direction.

Numerous factors can cause the tire’s pressure to decrease. For instance, a tire with poor rubber, holes, etc. You may install a roof rack on your Ford Fusion and mount spare tires on the roof rack!

Solution: Test and Adjust the Pressure of Your Tires

The solution to this problem is testing out the PSI of your tires. To do so-

  • First, take a pressure gauge and take note of each tire’s PSI. Do this when the tires are cold.
  • Then, you have to inflate the tire to 32 PSI, which is the recommended PSI for Ford Fusion. To inflate the tire, you can use tire inflators at home, or you can use the air compressor at car shops.

    Note that, the recommended PSI of a car can change due to tire size. Make sure to close the valves of your tire properly after inflating them to the recommended PSI.

Iterate through these steps for all 4 tires of your Ford Fusion. After that, the tire pressure sensor fault should not trigger.

Reason 3: Radio Frequency Interruptions

Any interruptions in the radio frequency of the Ford Fusion may cause the tire pressure sensor to trip. Although this reason seems very rare, many people are suffering due to it without knowing.

The tire pressure sensors of the Ford Fusion communicate with the system via signals. Each tire of the Ford Fusion sends out a signal to the car’s dashboard, which then causes the tire pressure sensor fault to occur. This happens when your car is moving.

When there’s any external USB port/cellphone charger plugged inside your car, it may cause this issue. 

Furthermore, it can happen when the volume of radio frequency signals is high in an area. For example, near airports, radio stations, etc. It throws in a 2278A error code when the tire pressure modules cannot communicate with each other for a long time.

Solution: Remove All USB Chargers and Accessories

The solution to this issue is quite simple; you have to remove all the chargers and accessories connected inside your car. These can create radio frequency which is strong enough to disrupt the tire pressure sensor’s workflow.

If you have to use a phone charger in your car, go for chargers that are of good quality. That way, they won’t create any interference with the system of the car.

Frequently Asked Questions (FAQs):

Do TPMS Sensors Have Batteries?

Yes, direct TPMS sensors have batteries inside of them and indirect TPMS sensors don’t have batteries. These batteries cannot be charged from the outside and must be replaced when dead.

Can Tire Pressure Sensors Be Removed?

Yes, tire pressure sensors can be removed manually from the tires. However, it’s not recommended as the driver won’t be aware of the tire pressures when the sensors are removed.

Where Is the TPMS Sensor Located?

The TPMS sensors are located inside the tire, between the tire and the wheel trim. The indirect TPMS sensors are located near the ABS of a car.


That’s all the information you’ll need regarding the ford fusion tire pressure sensor fault. Hopefully, you have no confusion and everything is crystal clear.

Always keep in mind that, you don’t have to fix the issues of your car all by yourself. In exchange for a reasonable labor cost, car mechanics will solve your issue in no time!
