For your car to work, the tyres need the right amount of air pressure. As long as you keep the right pressure in your tyres, they will last a long time. In the same way, it makes the car use less gas.
Modern pressure monitoring systems can help the driver know what’s going on. The user will know right away how much air is in the tyres. But the system could fail and send you the wrong message.
Tire Pressure Monitoring System (TPMS) lights up most of the time. If the tyre pressure drops, it will happen. It will light up exactly if the pressure drops 25% below what is needed. In our case, the TPMS may be sending out wrong information. What can you do?
Reasons behind Low Tire Pressure Light but Tires are fine
There are times when the tyres are neither too low or too high. Your dashboard’s TPMS light is on, which is bad. One or more of the following could be why:
1. Faulty TPMS tool
When you turn on your car, the pressure light may always come on. In this case, it’s a sign that the TPMS tool isn’t working right. You can look at the tire’s condition before calling a mechanic.
As soon as you know the tyre pressure is fine, fix the TPMS tool.
2. Extreme Cold Weather
When it’s cold, the tyre pressure tends to go down. Even if you inflated it right, it will happen. Matter tends to shrink when it’s cold and grow when it’s hot. So, if you are driving when it is cold, the problem goes away when the tyres warm up.
As the tyres warm up and nothing changes, check the tyre pressure. If everything is fine, it could be the cold weather.
3. Recent Tire Replacement
The TPMS tool must be on the tire’s rim for it to work well. When you change a tyre, the TPMS can get broken. When you change a tyre, it is very important to check the pressure light.
Other valid reasons may be as follows:
TPMS sensors are powered by batteries that last between 6 and 10 years. If they get weak, there will be a break in the signal. When this happens, the low-pressure warning lights will come on.
If something like tyre sealant gets into the tyre, it could cause damage. Because of this, it is likely to damage the TPMS sensors. If a sensor is broken, it will automatically stop sending signals to the dashboard.
TPMS are electronic components. If they have a problem on the inside or a short circuit, the signal will not work. It won’t be able to talk to the dashboard. This will cause the low-pressure light to come on.
There might not be enough air in the spare tyre. Do you know that there may be a pressure sensor in some spare tyres? It’s easy to forget to check how much air is in the spare tyre. It happens when you change the pressure of tyres that are already in use.
How to check a Faulty Tire Pressure Monitoring System
You can figure out what’s wrong by doing the following. The TPMS light is on in our case, but the tyres are fine.
- a) The system can be reset while you watch what happens.
- b) Check for broken sensors and replace them if you find any.
You should always do the following to make sure what the problem is.
Start the car and take it for a quick spin. The warning light should be on for a few seconds in most cases. The same lights should turn off after that.
If the warning lights stay on all the time, drive to the gas station closest to you. You could also go to a tyre shop and find out the air pressure there.
If your tyre pressure is less than 25% of what is recommended, the lights will come on. When it’s cold, the pressure in the tyres could go down. As you drive for a short distance, the tyres may warm up and regain pressure.
If you finish the step above and nothing happens, move on to the next step.
Here are the steps you need to take to reset the TPMS.
Turn the key ON, but don’t start the car.
Press and hold the TPMS reset button to move forward. Wait three seconds, then let go. The system will start to beep right away, and then it will turn off the warning lights.
You can start the car’s engine and drive it for half an hour at 19 mph. To end the reset process, you can wait one hour.
If the warning lights won’t turn off, you should replace the TPMS sensors. You can drive to a dealership shop to find out what to do next.
It’s important to remember that you should only reset the TPMS as a last resort. Don’t always do it when the waning light comes on.
Since technology changes quickly, it’s likely that new types of TPMS will come out. Before you start your car, it’s best to check the tyre pressure. You can do a physical check while figuring out how much air is in the tyres.
You should buy a small tyre pressure gauge if you are a driver. The tool can be used to figure out the real tyre pressure. You can check the pressure of your tyre with your hands. You could also use your TPMS tool.
Do you know that the only part of a car that touches the ground is the tyre? If the tyre is too full or too empty, the results are worse.
You shouldn’t drive with tyres that are too full of air. It could lead to things like tyres wearing out faster than they should. Also, as a driver, you may have to deal with a rough ride and strange handling. If your tyres are too inflated, the TMPS will not light up.
Concerning that, you can go a long way on tyres that are pumped up too much. So, it may cause a lot of wear and tear that you don’t even know about.
If you drive with tyres that aren’t inflated enough, the tyres could break. It’s hard to drive on a tyre that has low pressure. The tyre will have a big rolling surface. The situation could have a big effect on how well the car runs.
Also, the amount of friction will go up. Because of this, it will cause your tyre to get too hot. Tires will automatically wear out faster if there is too much heat. Still, the heat could make the treads come apart.
Driving with tyres that aren’t inflated enough is only good in some situations. If you are riding on sand, loose gravel, ice, or snow, it might be true. On a smooth road, it’s the other way around. For comfort and safety, you need to drive with the right tyre pressure.
Your car needs a TPMS tool to make your job easier. But you need to know how to keep the machine in good shape. Read the instructions every time you use this tool. If you find a tricky technical part, you should ask the mechanic for help.
You can also take care of it by following the tips below.
Let a reputable dealer do the work on your tyres or put them on. By hiring professionals, they know everything there is to know about putting on and taking off wheels. They will take care to keep the wheels in good shape without hurting the TPMS.
Tires that are worn, old, or damaged must be replaced right away. Doing so is a safety measure. The rules of the road say that no one can drive a car with bad tyres. Depending on where you are, you may have to pay a fine.
Always check the pressure in your tyres as a matter of course. On the other hand, you should make sure your tyre is properly inflated before you turn off the TPMS light.
Some things must be done with the help of an expert or a dealer. It could be replacing the original wheels. You can replace them with aftermarket wheels that are bigger. Notably, the process is usually busy because it changes how the TPMS was set at the factory.
Making sure that the car’s tyres have the right amount of pressure. Check on it once a week or once a month.
Check how deep the treads are. With the right treading, the vehicle will be able to move in the right way.
Every 6000–8000 miles, you should turn the tyre.
Every 4350 miles, check the alignment of the tyres or the suspension. This will keep tyres from wearing out unevenly.
Every time you get a new set of tyres, you should do tyre balancing. Tire balancing is something that can only be done by a professional.
If you see some false warning signs, it can be a frustrating experience. The whole thing will keep you from being calm as a driver. A low tyre pressure light coming on when the tyres are fine is not something new.
As a driver, you should do what you need to do to deal with the situation. This article gives the right advice to follow. If you use them all and do what they say, you can succeed. There may be some things that need the help of an expert.
If you use the right tyre maintenance tips, your car will be in good shape. You should do them often to avoid regrets in the future. By doing these things, you’ll be ready to drive your car safely to your destination.
Last but not least, your car is in good shape. You can use it in the right way to get to where you want to go.
