What Does Service TPM Mean – Complete Instruction

What does service TPM mean? Modern automobiles are built with a variety of devices that alert us when anything is wrong.

Whether it’s an auditory warning or a light on our dashboard, our car’s technological devices keep us informed.

The TPMS system is one of these critical alert systems. To understand what the light represents, it’s necessary to first understand what TPMS is and what it accomplishes.

What Does Service TPM Mean?

The Tire Pressure Monitoring System (TPMS) is a device in our car. The serv TPM meaning is to alert us once our tires are under-inflated.

This early-warning mechanism will assist us in avoiding larger issues caused by flat tires.

It is helpful in uneven or quick tread wear, poor handling performance, decreased fuel efficiency, and even catastrophic tire failure and damage.

The TPMS will collect data from sensors banded in each wheel or sensors in the car wheels attached to the valve stems.

They detect tire pressure and transmit that data to our car’s computer. When the tire pressure is too low, the car light TPMS on our dashboard will glow to alert us that a tire is underinflated.

What Is Tire Monitor System Light? 

In some circumstances, it is just there to alert us of low tire pressure. However, if it remains glowing after refilling the tires, it may signify a more serious problem.

Consider the placement of such sensors.

The sensors sit within or close to the wheels and are frequently susceptible to all bumps. They are not strong with the continual spinning action the wheels undergo as we drive.

Many road pollutants may wreak havoc with indirect TPMS, while pothole drives may result in the same for direct TPMS. Also, these sensors might malfunction and wear out over time.

Once the service tire monitor system warning appears, tire pressure might be at or below desirable levels.

The tires could be damaged and unable to keep the proper tire pressure. As a result, we may encounter issues such as:

Inadequate tire pressure light has no advantages, just disadvantages. That is the intent of this warning.

A healthy car relies on ensuring proper tire inflation or identifying and fixing system malfunctions as soon as feasible.

What Does Service TPM Light Mean?

Whenever the TPMS light illuminates, we should pull over and inspect the air pressure in every tire. Check that they are filled to the required PSI level per the car manufacturer.

This number may be found on our car’s door jamb, in the owner’s handbook, or we contact dealers. Our tire monitoring system light may notify us in a variety of ways.

TPMS Light Turns On While Driving 

Should the TPMS light illuminate while traveling and not turn off, at least one of our tires is likely underinflated.

Once the light turns on and remains on, we ought to stop and examine the tire pressure.

TPMS Keeps Turning On And Off

The air pressure in our car tires can be affected by changes in temperature outside.

For example, cold weather or an abnormally chilly morning could lead our tires to lose pressure, triggering our TPMS light. 

But as the day progresses, the air in the vehicle tire will return to normal, leading the TPMS light to switch off.

In case the TPMS light continues flashing on and off, use a tire gauge to confirm that each tire is correctly inflated.

TPMS Light Flashes And Then Stays On

When we activate our automobile, we might experience all of the lights on our dashboard glow briefly before turning off.

However, if our TPMS warning light blinks and then remains on after we start the car, it implies our TPMS system needs to be serviced.

It’s generally an indication that there’s a problem with the system. It’s not working correctly. If it happens, go to our dealership service center right away to get our system repaired.

It can notify us when our car tire pressure is too low.

TPMS Malfunction 

The tire pressure monitoring system (TPMS) in our vehicle is intended to assist us in maintaining our tires.

However, when our TPMS is defective or poorly installed on our wheels, it may be broken while driving. Many outside factors can also damage the tire pressure sensors.

This damage could result in a loss of tire pressure or other TPMS flaws. It can also display false alerts, causing worries to the passengers.

Don’t allow TPMS failures to prevent us from traveling safely. Maintain the proper operation of our TPMS by having it serviced by experts periodically.

What Is The Purpose Of Service Tire Monitor System Light?

Under- and over-inflation of tires may cause many problems for drivers. Some adverse scenarios are poor traction, excessive tire wear, decreased load-carrying capability, and even a blowout.

Meanwhile, a correctly inflated tire will minimize tread movement, increasing tire life. Besides, it can also help lower rolling resistance to improve vehicle economy.

A properly inflated tire will improve water dispersion, which reduces the possibility of hydroplaning.

Thus, ensure we have the correct numbers by consulting our owner’s handbook. It is critical for our safety to maintain our tires well-inflated. In the long term, this can save us money and worry.

How To Fix Service Tire Monitor Light?

When our TPMS indicator illuminates, the first step is to examine our tire pressure. Low tire air pressure is the most common cause of the TPMS indicator turning on.

Thus, to reset the tire pressure monitor light, fill our tires to the correct pressure and never over inflate the tires. Instead, refill them to the maker’s suggested tire pressure.

If our tire air pressure indicator remains illuminated regardless of whether we’ve given the proper air quantity to the car tires, we must reset it.

We may reset the TPMS warning light by following the below procedures.

Suppose we have little mechanic knowledge, we can bring our car into one of our local service facilities. They will check the current tire pressure thoroughly and take care of the problem for us.

How To Reset Service Tire Monitor Light?

When our TPMS indicator stays illuminated after properly filling our tires, try the following steps. For approximately 10 minutes, travel at 50 mph.

It will reset the tire sensors. The TPMS light will be turned off the next time we restart the car.

Put the key in the “on” position when the car is turned off, but do not start it. Push the TPMS reset button until the tire air pressure indicator flashes three times, then let go.

Ignite the vehicle and drive it for 20 minutes to enable the sensors to be cleared. The tire air pressure reset button may be found below the steering wheel.

If unable to find it, look in the car’s owner’s handbook.

There are two more time-consuming methods for resetting the TPMS light. Inflate every tire to 3 PSI more than the proper pressure levels, then deflate them.

If our spare tire has a sensor, please be sure to add that as well. After deflating all of the tires, refill them to the correct PSI. Plus,

Lift the hood and detach the positive battery cable while the car is turned off.

Set the key to the “On” position and blast the horn for around three seconds to discharge any remaining electricity in the vehicle. After that, reattach the battery.

Frequently Asked Questions

Will The TPM Light In Car Reset Itself? 

After filling our tires, we may reset the alert light on some cars by pushing or turning on the instrument panel.

On certain vehicles, however, the TPMS light automatically adjusts itself and turns off the TPMS alarm light.

Otherwise, it will turn off after a few miles of driving after the tires have been re-inflated.

How Do I Service My Tire Monitor System?

Maintaining a tire monitor system necessitates using special tools, extensive technical knowledge, and the necessary parts for the vehicle. It is not something that can be undertaken at home.

The best method to get it serviced is at a certified dealership’s service department. They will have all the know-how required to service ours and low costs to make it a breeze.

What Does It Mean When Your Car Says “Service Tire Monitor System”?

The system will show a message instead of a warning light in certain models. A “service tire monitor system” alert from Chevrolet might imply one of two problems.

The first meaning is that our tire air pressure is too low and has to be adjusted to manufacturer-recommended standards.

The second interpretation applies when the alert does not disappear after refilling the tires or if a flashing TPMS light accompanies it.

It indicates that the system has failed and must be diagnosed and serviced by an authorized service location.


What does service TPM mean? It alerts us of low tire pressure. We need to refill the tire to the producer’s recommendations.

We can find the number in our handbook. In case the alert does not disappear after having proper inflation, we can try to reset it with the above instruction.
