Tire Pressure Monitor Problem: Causes And Fixes

A tire pressure monitor problem occurs when the system fails or starts to malfunction. But proper tire pressure is necessary for the performance, load capacity, and fuel economy of the vehicle. 

However, the required pressure for tires will differ from vehicle to vehicle. TPMS will signal when the tire pressure fluctuates from the required value. If the pressure is too low, there is a risk of a tire blowout, which might also cause an accident.

So, it is necessary to take the problem with concern and fix it quickly. In this article will enlighten you about the problem, its causes and solutions with caution. Let’s dive in and learn the issues and fixes.

Caution While Fixing The Tire Pressure Monitor Problem

What Is The Tire Pressure Monitor Problem?

The tire pressure sensor inside a tire ultimately sends signals to the dashboard. Generally, this TPMS indicates some issues, primarily the low pressure on the tire by flashing the TPMS warning light.

Usually, the major TPMS problems are:

Periodic On And Off

This issue occurs due to temperature changes, mainly in winter. Because due to temperature fluctuations, the tire pressure will also vary. This will result in this type of blinking of the warning light.

The Light Comes Out And Stays On Constantly

Once the warning light comes on, it will not go out and will stay like this. There might be two reasons for this happening. Firstly, if the tire’s pressure is low, it will turn the light on. Another reason can be that the sensor itself is faulty.

Causes Of Tire Pressure Monitor Problem

Several reasons can cause the malfunction of the tire pressure monitoring system. Such as:

  • Failure of the sensor
  • Poor connections of the sensor
  • Low pressure
  • Environmental and temperature issues
  • Installation of new tires

We will now discuss how these factors can cause the malfunctioning or failure of the TPMS:

1. Failure Of The Sensor

The tire pressure sensor contains batteries that are the primary reason for failing the sensor. Failure of those batteries means failure of the sensor. 

If the batteries lose their charge with time, the warning light will remain constant.  

Additionally, running out of power also causes this problem. However, other reasons can also lead to sensor problems. Most commonly, 

  • Corrosion on the sensor occurs in the stems that are made of aluminum. Luckily, the rubber stems are safe from this
  • The tire sensor is worn out 
  • External damage on the sensor 
  • A dirty sensor 

2. Poor Connection Of Sensor

The next issue with the tire sensor is the connection condition. This may disconnect or break due to incidents like heavy bumping.

You can see from the picture that the pressure sensor sends signals to the receiver. This receiver is connected to the display monitor, which further receives the signals.

So, if an interruption happens in connection with the sensors,  the dashboard will declare the issue. 

3. Low-Pressure

Low pressure is the most common reason for showing the light on the tire pressure monitoring system in all vehicles. The low pressure mainly occurs due to leakage. 

If the pressure on any of the tires is low, the light will immediately show up. In this case, you have to check the location of the fault manually sometimes. 

A few cars offer you the advantage of determining the exact location of the problem by remote control. But most of the time, you have to check the tires one by one to locate the issue by using a gauge. 

4. Environmental And Temperature Issues

The effect of Temperature will lead to the tire pressure monitoring system light being illuminated. Because the temperature directly affects pressure, and the pressure varies with the temperature change.

Inside the sensor, if the temperature is too low means cold conditions, the pressure also decreases. And for the opposite term means if the temperature increases, the pressure inside the tire will also increase. Hence, in both conditions, the tire pressure monitor problem will arise. 

5. Installation Of New Tires

If you install new tires or wheels on your automobile, you must consider all the above issues. After installing new tires, the sensor has to reconnect, and the pressure won’t be the same as before. That’s why the TPMS light will show up as the indication sign. 

Solutions To The Tire Pressure Monitor Problem 

As you know the causes of this problem, it will be more effortless to understand the resolving process. You can easily resolve this problem by following a few simple steps. 

1. Fixing The Sensor

The solution to this problem starts with fixing the tire pressure sensor. Here are the steps to fix it:

Step 1: First, measure the air pressure appropriately with any pressure-measuring device. A pressure gauge (our pick) will be suitable for this operation as it will ensure an almost accurate reading of the pressure

Step 2: Leave the tire for some time to let it cool down

Step 3: To access the tire, you have to remove or open up the screws

Step 4: Now, you have to measure the pressure again

Step 5: Set the proper pressure if there is a deflection from the recommended pressure

Step 6: Reset the Tire Pressure Monitoring System

2. Fixing The Constant Light Issue

Sometimes, the light stays on even if you put sufficient air pressure on the tires. In such case, you can follow this:

  • Drive the car for 10 minutes at a moderate speed
  • At rest, press and hold the TPMS button till the warning light blinks three times
  • To reset the sensor, start and drive the car for more than 20 minutes

Caution While Fixing The Tire Pressure Monitor Problem

If you are not cautious enough while fixing the sensor problem, you might damage your vehicle instead of solving the issue. However, the following  cautions should be in your consideration:

  • While measuring the pressure using a gauge, ensure the tightness is enough
  • Remember to make sure there is no leakage of flammable gases
  • While checking the tire pressure, ensure the surface is holes and rocks-free. Otherwise, the pressure might not be accurate 
  • Use damage-free service kits
  • Relearn needs before servicing any vehicles
  • If you are not experienced enough or can’t fix the problem yourself, you must ask for the help of a mechanic 

Frequently asked Questions (FAQs):

In this FAQs section, we will answer a few most asked questions about the tire pressure monitor problem.

What Is The Tire Pressure Sensor Replacement Cost?

There is no actual price of the sensor as it varies with the models and years of the vehicle. But the price is low, generally ranging between $70-$200 for a single tire replacement. For luxurious cars, the cost will rise a little bit .

When To Replace The Tire Pressure Sensor?

The tire pressure sensor can be replaced when needed. But the manufacturer company makes it with a lifespan of 5-10 years. That’s why if there are no defects, you still need to replace the sensor periodically after five years.

Can I Drive A Car With Tire Pressure Monitor Problem?

Yes, you can still drive your car with lightning in the tire pressure monitor system. However, a small run to the garage or mechanic shop is good. The long run or continuous run can end up with adverse effects.


Higher tire pressure generally causes low fuel economy and a better driving experience. But if the pressure is low, wearing tires may occur, which may cause a blowout. That’s why the TPMS monitors the tire pressure.

But if the TPMS malfunctions, it will be tough for you to detect when the air pressure is low enough in the tires. From this article, you already know about the tire pressure monitor problem. You have to fix them if you don’t want to deal with the accident risks.
