If you ever see the Tire Pressure Sensor Fault message, it indicates that there is trouble with the TPMS. The tire might be overinflated or underinflated and it is affecting the air pressure of the tire. No matter what happens, we do not recommend you driving while the tire pressure sensor fault message is there.
Driving the vehicle with the TPMS light is on will result in undue wear on your car tires and eventually in tire failure or blowout! But there are ways to solve it! So, how to fix the tire pressure sensor fault to drive safely? Let’s learn!
What can cause a tire pressure light to come on?
Do you know what can cause the tire pressure light to come on? The basic reason for the tire pressure light coming on is the air pressure in the tires. If the air pressure in one or more tires is not maintaining the recommended range, this can happen.
This can also happen from the leak. The tires lose more or less one pound every month. If the temperature drops to 10-degree, for every 10-degree, the air pressure will drop 10 pounds. And eventually, it will result in the tire pressure light come on.
For this, checking the pressure with the racing tire pressure gauge can help you to be sure about it. No, this is not only the reason the tire pressure lighting is common on, you already know it! There are other reasons too. Before everything, check out the method of solving it and then learn why this happens!
Step by Step Fixing Tire Pressure Sensor Fault
Having the best road tire Polaris Ranger inside your RANGER 2007 or 2008 model is an amazing option to save the journey if the tire fails. But if the problem is in the pressure sensor of your tire, what can you do? Here is a way to reset the tire pressure sensor easily. Go through the steps and you’ll know!
- Direct TPSM: Here, the sensors are set in the pressure valve of the tire, or they are wrapped surrounding the rim of your wheel. For this, a band clamp is usually added. In the first case, it works as an antenna. With the help of these devices, the information is transferred to the onboard computer.
- Indirect TPSM: On the contrary, the indirect TPSM refers to the one where the sensors are set within the ABS braking system. In some situations, it can be set within the speed sensors of every single wheel. It works by checking out the wheel’s rotation speed and the changes.
Now, if you have a direct TPSM, things can be easy for you while resetting the tire pressure sensor. All you need to do is push a reset button on the dash and you are done! For this, you might need to check the manual. However, the indirect TPSM is not this easy.
Here, you can go through the rest process with the help of a magnet or scanning tool. Check your system properly. You might see a reset button added inside the glove box. If you get it, you have to get your hands inside and press it. Keep pressing it for about three seconds. Make sure that the ignition is on during this period!
Step 2: Tire Inflating
The second step that will help you reset the tire pressure sensor is the inflation of the tires. After you are done with the first step, go forward and inflate the tires of your vehicle. Use 120v tire inflators for this process. As you have to set the sensor once again to ZERO, everything needs to be in the default settings!
And for this, the tires should be inflated too. If you do not do it, the sensors will have issues regarding the calibration. Eventually, the readings you will see will be biased!
Step 3: Battery Checking
Now, it is time for you to check the battery of your car. Sometimes, for powering the sensor, vehicles use batteries. And at times, the battery can be dead too. If it is dead, this can be a reason for your tire pressure sensor fault. You have to check the battery and ensure it isn’t dead.
If it is dead, make sure you get your hands on a new battery and replace the old one. In the worst-case scenario, if the battery is built-in, you might need to work a little extra. In such situations, you have to replace the entire sensor-we know that’s tough but there’s no other way!
Step 4: Wheel Transponders Recalibrating
After checking the battery, go through the wheel transponders. Yes, every wheel will have one of these. And when you rotate a wheel, the responder’s location will change. Along with this, the TPMS will go through a new location. If you are going for this relearning process, make sure you know your vehicle well. It’s because not all vehicles have the same procedure.
For this, check the TPMS chart available in the owner’s manual. You can get it online too! If you are getting new tires, you can plan on changing the valve stems. When the tire pressure sensors are the valve stems, you should plan on doing it!
Step 5: Magnet Cover
Get your hands on the key of your car and make sure that the key is on while you do it. However, you must certify that the engine is off too! Go through the lock and unlock button on your key bob. With your fingers, press both of them. An initial chirp will take place here. Get a magnet cover and place it on the valve stem.
Cover all the valve stems with each magnet cover. Do it until you see that the horn chips for them are in the right order. You might be confused about the right order. Let us tell you, the left front, right front, and then the right rear and the left rear-this is the accurate order. On the driver information center, you will be able to see the pressure readings. That’s all you need!
Step 6: Reprogramming and Replacing
At times, no sensors are being replaced. In that case, the TPSM Reprogramming Procedure might help you. In some situations, if you have followed all these steps but it still isn’t working, you can settle for replacing the sensor. After you replace it, make sure you have reprogrammed the sensor once again to make it work fine! Keeping a digital tire pressure gauge in your car can help you learn about the pressure even on the road.
Tire Pressure Sensor Fault but Tires are Fine
Sometimes, the pressure sensors are faulty but the tires are fine. In short, there is low tire pressure light but you can see that the tires are doing just fine! What’s the issue then? There can be several reasons behind this.
- If the TPMS tool is faulty, the pressure light will turn on when you start the vehicle. And it will be on permanently. Repairing the TPMS tool will be helpful here.
- If you are driving in extremely cold weather, the tire pressure will go down. At times, some people ask “why is my tire pressure light still on after filling tires?” This is the reason behind it! The tire pressure can go down even if the tires are properly inflated.
- If you have replaced the tires recently, that can be another reason for the tire pressure sensor issue. If the TPMS tool is not working properly, checking the rim of your tire is necessary. During the process of replacing the old tire with a new tire, the TPMS sometimes gets damaged.
These are only the basic reason for the tire pressure sensor fault but other reasons can also make it stop working properly. Also, there are other fixes for the tire pressure sensor fault too!
We only have mentioned the easiest method to make it work. But if you are not confident enough, we recommend you to go to a profession and get it solved!
