Does your car have a TPMS? Have you ever asked yourself which tire in particular the TPMS indicator was referring to when it showed? Wait! Do you know what a TPMS or its sensor is?

If you’re wondering if all tires have TPMS sensors, the answer is unfortunately no. Not all tires are outfitted with TPMS sensors, though it’s becoming more and more common for them to be included as standard equipment.

If your vehicle doesn’t have TPMS sensors, don’t worry – you can still get a tire pressure monitoring system installed.

In this article, we’ll discuss what TPMS sensors are, why they’re important, and how you can make sure your vehicle has the best possible safety features. We’ll also provide some tips on how to maintain your TPMS system and keep it functioning properly.

What is TMPS?

TPMS, an abbreviation for Tire Pressure Monitoring System, is an electronic system in a car that monitors the tire air pressure. The purpose of the TPMS is to warn you that at least one or more tires are significantly underinflated. The TPMS indicator is the horseshoe-shaped light on the dash with an exclamation point in the center. It can also be an overhead view of a car with all four tires exposed.

Now, how do you know if your car has a TPMS? If you own a car manufactured after 2007, you most definitely have a TPMS at work there. However, even with these cars, there are still variations in how their TPMS work.

Let us just say you do not know which year your car was manufactured. An even easier way to know if your car has a TPMS is if the “low pressure” warning light appears on your dash when the key is turned to the “on” position.

Now that we know what TPMS is, let’s discuss why it’s important to have it in your vehicle.

Why is TPMS important?

As we’ve discussed, the primary purpose of TPMS is to warn you when one or more of your tires is low on air. This is important because it can help you avoid a flat tire.

In addition, TPMS can also help you improve your fuel economy. This is because lower tire pressure can cause your tires to flex more, which leads to increased rolling resistance. By keeping your tires properly inflated, you can help reduce rolling resistance and improve your fuel economy.

TPMS can also help you extend the life of your tires. This is because proper tire inflation helps to reduce tread wear. By keeping your tires properly inflated, you can help extend their life and get more miles out of them.

As we can see, there are many reasons why TPMS is important. If you don’t have TPMS in your vehicle, we recommend that you consider adding it.

How does the TPMS work?

TPMS sensors are located on each wheel, and they constantly monitor the air pressure in your tires. When the pressure in one or more of your tires is too low, the TPMS sensor sends a signal to the TPMS warning light on your dash. The TPMS system will also usually provide you with information about which tire or tires are affected.

It is important to note that the TPMS system does not measure the actual air pressure in your tires. Rather, it uses sensors to detect when the tire pressure is too low and then activates the warning light on your dash.

TPMS sensors use a variety of different technologies to monitor your tire pressure, including:

  • Radiofrequency
  • Magnetism
  • Inductance
  • Capacitance

Which technology is used depends on the make and model of your vehicle.

Types of TPMS Sensors

There are two types of TPMS sensors namely Direct and Indirect TPMS sensor

1. Direct TPMS:

This type of TPMS uses sensors mounted inside the tire to measure the pressure. The sensors are powered by batteries, and they send signals to a receiver that is mounted on the vehicle. When the tire pressure drops below a certain level (25%), the receiver will activate the TPMS warning light on your dash.

There are 2 types of direct TPMS sensors namely:

-Analog sensors: These are the most common type of direct TPMS sensor, and they use a radio frequency to send signals to the receiver. When the tire pressure drops below a certain level, the receiver will activate the TPMS warning light on your dash.

-Digital sensors: These are less common than analog sensors, and they use a wireless signal to send signals to the receiver. When the tire pressure also drops below a certain level, the receiver will activate the TPMS warning light on your dash.

The direct TPMS consists of four main components:

  • Sensors: These are mounted inside the tires and measure the pressure.
  • Batteries: These power the sensors and can last for up to five years.
  • Receiver: This is mounted on the vehicle and receives signals from the sensors. It will activate the TPMS warning light if the pressure in one or more tires is too low.
  • Warning light: This is located on the dash and will come on when the receiver detects that the pressure in one or more tires is too low.

2. Indirect TPMS:

This type of TPMS uses sensors that are mounted on the wheel to measure the speed of each wheel. The sensors send signals to the TPMS control module, which uses algorithms to calculate the pressure in each tire. When the pressure in one or more tires is too low (25%), the TPMS control module will activate the TPMS warning light on your dash.

The indirect TPMS consists of four main components:

1. Sensors: These are mounted on the wheels and measure the speed of each wheel.

2. TPMS control module: This receives signals from the sensors and uses algorithms to calculate the pressure in each tire.

3. Warning light: This is located on the dash and will come on when the TPMS control module detects that the pressure in one or more tires is too low.

4. Tire pressure gauge: This is used to check the pressure in each tire.

It is important to note that the indirect TPMS is less accurate than the direct TPMS, and it may not activate the warning light until the pressure in one or more tires has dropped below 20%.

Direct vs Indirect TPMS

There are differences between the direct and indirect TPMS. Examples are:

1. Accuracy

The first difference between direct and indirect TPMS is accuracy. As mentioned earlier Direct TPMS is more accurate because it uses sensors that are mounted inside the tires to measure the pressure. Indirect TPMS is less accurate because it uses sensors that are mounted on the wheels to measure the speed of each wheel.

2. Type of sensor used

Another difference between direct and indirect TPMS is the type of sensor that is used. Direct TPMS uses sensors that are mounted inside the tires, while indirect TPMS uses sensors that are mounted on the wheels.

3. Transmission

The last difference between direct and indirect TPMS is the way the information is transmitted from the sensor to the receiver. Direct TPMS uses a radio frequency to send signals to the receiver, while indirect TPMS uses a wireless signal.

Reasons to choose direct TPMS:

  • More accurate than indirect TPMS
  • Sensors are mounted inside the tires
  • Uses a radio frequency to send signals to the receiver

Reasons to choose indirect TPMS:

  • Less expensive than direct TPMS
  • Sensors are mounted on the wheels
  • Uses a wireless signal to send signals to the receiver
  • The indirect TPMS is less accurate than the direct TPMS, and it may not activate the warning light until the pressure in one or more tires has dropped below 20%.

If you are unsure about which type of TPMS to choose, I recommend that you consult with a professional. They will be able to help you choose the right TPMS for your vehicle.

Benefits of TPMS

There are several benefits of TPMS, which include:

1. Helps to maintain proper tire pressure

The first and most important benefit of TPMS on your tire is that it helps to maintain proper tire pressure. Proper tire pressure makes for a safer ride, It makes driving less stressful and fun when your tires are inflated to the correct pressure.

If you have ever driven on a tire that is low on air, you know how important it is to maintain proper tire pressure. The TPMS system will help you do this by monitoring the pressure in your tires and sending you a warning when one or more tires are low.

2. Helps to extend the life of your tires

Another benefit of TPMS is that it helps to extend the life of your tires. This is because proper tire pressure helps to prevent flats and other damage to your tires and also prevents you from having to purchase new tires. After all, your tires will be well maintained and can be used for a long time. You can check out this cool and affordable AstroAI Tire Inflator on Amazon

3. Helps you save money on fuel

Another benefit of TPMS is that it can help you save money on fuel. This is because proper tire pressure helps to improve fuel economy. When your tires are not properly inflated your car turns to use too much fuel because of the resistance.

4. Helps you avoid accidents

The last benefit of TPMS is that it can help you avoid accidents. This is because proper tire pressure helps to improve your vehicle’s handling and braking. When your tires are properly inflated, you will have better control of your car, which can help you avoid accidents.

Tips on how to maintain your TPMS

Check your owner’s manual to see if your vehicle has a direct or indirect TPMS.

1. Inspect the condition of your tires regularly.

You should regularly check the condition of your tires because they are the only contact between your vehicle and the road. If they are worn or damaged, it can affect your ability to stop or turn.

2. Check tire pressure at least once a month.

You should check the pressure in your tires at least once a month, and more often if you drive frequently or in extreme conditions because these conditions can affect tire pressure.

3. Replace flat tires as soon as possible.

Replace your tires as soon as possible if you have a flat, this will help to prevent further damage to your tires and TPMS.

4. Check TPMS after tire rotation

If you have a direct TPMS, the sensors will need to be checked every time you get your tires rotated or changed. This is because the sensors are mounted inside the tires and can be damaged when the tires are removed.

When to replace the TPMS

There comes a time when everything comes to an end, and your TPMS is no different. The average lifespan of a TPMS sensor is about five years, after which it will need to be replaced. However, this can vary depending on the type of vehicle you have and how often you drive. If you drive frequently or in extreme conditions, your TPMS sensors may need to be replaced more often.

There are several causes of a bad TPMS namely:

1. Rusting sensor

Rust is a major factor in the deterioration of your TPMS sensor. If you live in an area with a lot of salt on the roads, this can speed up the process. Also, weather conditions can easily cause it to rust because of the moisture in the air.

2. A direct hit

Another cause of a bad TPMS sensor is a result of a direct hit, If you hit a pothole or something else that causes a direct impact on your tires, it can damage the sensors. This is why it’s important to regularly check the condition of your tires.

3. Corrosion

Corrosion is also another factor that can cause the sensors to malfunction, It occurs when the battery in the sensor dies and corrodes the sensor. This can cause it to stop working altogether. When this happens you need to replace the sensor.

4. Wiring problems

Again wiring can also cause the sensor to malfunction, If the wires that connect the sensor to the vehicle become damaged, it can cause the TPMS to fail.

5. A faulty sensor

Sometimes, the sensors just go bad and need to be replaced. Faulty sensors are mostly caused by manufacturing defects.

6. A build-up of dirt and grime

Dirt and grime can also cause your TPMS sensor to fail. This is because it can build up on the sensor and prevent it from working properly. As the car moves on the road it attracts specks of dirt and grimes which build upon the sensor.

7. A broken seal

Finally, all TPMS sensors have seals that prevent moisture and dirt from getting into the sensor. However, over time these seals can become damaged or broken, which will allow moisture and dirt to get in and cause the sensor to fail.

If you notice any of these problems with your TPMS, it is time to replace it.

Problems of Bad TPMS

Bad TPMS can cause several problems such as:

1. Decreased fuel economy

The first problem of a bad TPMS is decreased fuel economy. This is because the sensor is not working properly, and as a result, the car’s computer cannot adjust the air pressure in the tires correctly. This can lead to increased friction between the tire and the road, which can cause your car to use more fuel.

2. Decreased handling

Another problem of a bad TPMS is decreased handling. This is because the car’s computer cannot adjust the air pressure in the tires correctly, which can lead to problems with the grip of the tires on the road. This can make it difficult to turn or stop your car.

3. Increased wear and tear

Bad TPMS can also cause increased wear and tear on your tires. This is because the car’s computer cannot adjust the air pressure in the tires correctly, which can lead to uneven wear on the tires.

If you have a TPMS sensor, it is important to regularly check the condition of your tires and replace them as soon as possible if they are damaged. Additionally
