How to Reset Service Tire Monitor System? Easy Guide

Your vehicle comes equipped with a built-in tire pressure monitoring system (TPMS) that alerts you to any tire pressure difficulties. When the TPMS light illuminates, it indicates that something needs to address.

It could be a simple tire pressure sensor problem, and all that is required is to reset the tire light. As a result, I’ll cover How to Reset Service Tire Monitor System in this article.

The tire pressure light’s purpose is to notify you of a possible tire problem. Because the service tire pressure monitoring system (TPMS) is a critical safety feature on your car, truck, or SUV, you should always ensure active and functioning correctly.

What Does Service Tire Monitor System Mean?

When a tire is low on air, the tire monitor system activates. A light in the message center on your dashboard will illuminate, or a message will flash over the screen informing you that you have a low tire. Certain vehicles will even notify you of the pressure in each tire.

Typically, the indicator will illuminate when the tire is low and then turn off. On the other hand, you have a significant problem if the light remains on.

It often indicates that the tires are 25 percent under the recommended air pressure. Occasionally, your tires are excellent. As with every component, monitors can wear out or fail. As a result, your tire monitoring system may also be faulty.

Tire pressure monitoring systems use sensors to keep an eye on the air pressure in your tires. Typically, the sensors locate inside the tire and link to the rim. Anything that endures a harrowing journey, such as this sensor, will eventually lose its efficacy.

Purpose of TPMS

The Tire Pressure Monitoring System in your vehicles designs to alert you if one or more of your tires is considerably under-inflated, potentially resulting in risky driving conditions.

The TPMS low tire pressure indication is a yellow symbol in a tire cross-section (which looks like a horseshoe) with an exclamation mark that glows on the dashboard’s instrument panel.

Efficient ways to Reset a Service Tire Pressure Monitoring System

Tires on our vehicles are constantly in use, and air can escape over time, resulting in tire deflation. If the tire pressure exceeds 25 PSI, the tire monitor service light will illuminate immediately.

When your tires inflate, the tire pressure light should automatically turn off. If it remains on, reset it. To know How to Reset Service Tire Monitor System use one of the following methods:

By Driving at or Above 50 Mph

For 10 minutes, maintain a speed of at least 50 mph. It may result in the tire pressure sensor reset the next time the vehicle starts. 

By Resetting the TPMS Using the Reset button

  • Switch the key to the “on” position with the vehicle turned off, but without starting it. 
  • Reset the TPMS by press and hold the reset button until the tire pressure light blinks three times, then release it. 
  • Start the vehicle and wait for 20 minutes for the sensor to re-calibrate. You position beneath the steering wheel the TPMS reset button. If you cannot locate it, consult the owner’s manual for your car.

By Resetting the Tire Pressure Monitoring System Sensors

When you have done inflating or deflating your tires (in the case of excessive PSI) or altering a tire on your vehicle, you should always reset the tire pressure system.

In some instances, the sensors may be out of sync with one another; in these instances, a method requires to reset the service tire monitor system

  • Place your vehicle in the park position. Then Start the ignition key to the RUN setting with the engine turned off.
  • It will reset the car and sound the horn twice before the tire pressure monitor service light starts to flash. Toggle the headlight switch from ON to OFF 4 times within three to four seconds to reset the truck.
  • Drain all air from the vehicle’s front tire on the driver’s side. Then, deflate the tire for ten seconds, and the truck’s horn will sound.
  • Reinflate the tire once the horn stops blaring. The system may have reset, so you must repeat the procedure. Each beep signifies that the tire sensor successfully connects to the monitoring system.
  • Repeat the procedure for each tire. The horn will beep twice to indicate the completed process when the final tire inflates.
  • It is now necessary to switch off the vehicle. Then Fill each tire to the proper pressure levels using the air compressor.
  • Restart the vehicle and verify that the TPMS light illuminates.

By Inflating and Deflating Tires

  • Inflate all tires three PSI higher than the manufacturer’s recommendation, then completely deflate them.
  • Include the spare tire, as it may equip with a sensor. Reinflate them to the recommended tire pressure once they fully deflate.

By Unplugging the Positive Battery Cable

  • Turn on the automobile and turn off the engine for around three seconds. It will drain any remaining battery power in the vehicle. 
  • Replenish the battery, and then reconnect it.

Update the TPMS Sensors

When changing tires, it is vital to take care when removing and reinstalling the sensors. In some circumstances, typical corrosion may cause harm to the sensors, but an unethical tire technician may also cause damage if they do not remove it correctly.

So to know How to Reset Service Tire Monitor System by changing TPMS sensors, follow the steps mentioned below:

  • Pull the valve core carefully from the TPMS sensor. Allow for deflation of the valve.
  • Pull the TPMS sensor grommets apart and discard them using the ratcheting and socket. A washer may be included beneath the grommet to minimize leakage in rare instances.
  • The tire pressure monitoring system (TPMS) sensor valve should recess into the tire rim. The sensor will autonomously slide toward the tire’s bottom and into the groove by fastening the bead onto the tire changer.
  • Utilize a normal tyre changer to repeat this procedure on both rim edges.
  • Secure the tire on the tire changer table with adjustable clamps to prevent slipping.
  • Separate the wheel from the rim by lowering the tire’s top bead. By accessing the TPMS sensor from the outside, you can remove it from inside the tire. If replacing the wheel, you may remove the bottom bead from the rim, but if not, you must replace the top bead with the lower bead.
  • To successfully install the new TPMS sensor, it is necessary to insert the rubber gasket (included in the kit) on the sensor valve.
  • Position the tire sidewall in front of the valve opening in the rim, press the sensor valve down, and then up into the hole. With one hand, secure the washer (if present) and a grommet in place with the other.
  • Lastly, Inflate the tire to the correct pressure as usual.

Service Tire Monitor System Cost

The price of tires varies widely based on the type of tire you require. If you need economy tires for a little automobile, you might spend as little as $50 per. However, you can pay as much as $1,000 per tire if you drive a heavy vehicle and want some sturdy rubber. A quick rundown, as it were:

Tires TypeTotal Cost (Each)
Low End Tire$50 to $150
Mid Range Tire$150 to $300
High End Tire$350 to $1000

Simply the price of the tire itself is reflected here. The new tires cost does not include the labor involved in mounting, balancing, and putting them on your vehicle. If you don’t want your old tires, the installer may charge you to get rid of them.

Cause of Service Tire Monitor System Light Blinking?

#1) Issues with the Battery

In conjunction with the alternator, the battery provides continuous power to all interior electronics save the tire pressure monitoring system (TPMS). The TPMS is housed within the rim, making it impossible to connect the battery practically.

Since the TPMS sensor doesn’t need power from the car’s primary battery, it typically comes with its little battery. Eventually, the battery inside the TPMS sensor housing will fail like any other battery. Batteries used in TPMS sensors usually last between five and six years.

#2) Tires That Have Lost Air Pressure

The most common cause is under-inflated tires. These devices are built on the fact that tires gradually lose air pressure over time and are thus able to detect this phenomenon. Pump air into the tires and start the car again to solve the problem. If the warning light stays on, it’s not your tires.

Also possible in the case of a gradual puncture. Because of this, if this light turns on, you should check your tires for damage.

#3) Poor Sensing

As was noted at the outset, these TPMS sensors can occasionally fail due to the strain they’re put on when driving, especially on rough terrain. They are especially vulnerable to vibrations due to their location inside the rim.

Changing the sensors is a simple solution to one of the most common causes of the service TPMS light coming on. Depending on how often you drive, a TPMS sensor should last anywhere from 5-10 years, according to experts.

#4) Aggressive Potholes

These sensors are so low to the ground that the vehicle’s movement constantly jostles them. Because you hit a particularly nasty pothole, the data they capture may be misinterpreted. The sensor may falsely read that your tires are underinflated if subjected to such a strong disturbance.

In most cases, restarting the car fixes the problem. However, if the problem persists, it’s likely due to the broken sensor failing because your tires are deflating because of blunt force collision.

Frequently Asked Question

What Do It Mean When It Says Service Tire Monitor System?

The Tire Pressure Monitoring System designs to inform you when your tire pressure is too low, resulting in risky driving situations. Your tires may underinflate if the indicator is on, resulting in excessive tire wear and eventual tire failure.

Can You Turn Off Tire Pressure Monitoring System?

Yes, you can disable them if you desire; however, this does not recommend, and you will need to reconfigure them for your car. The most straightforward approach to disable them is to replace the red wire in pin 2 with the blue wire in pin 6.

Where Is the TPMS Reset Button?

The TPMS reset button locates beneath the steering wheel on most automobiles. After replacing your vehicle’s tires, the TPMS must be electrically reset to clear the problem code. Push and hold the TPMS reset button until the tire pressure light flashes three times, then release.


Tire Pressure Monitoring System (TPMS) is an automatic instrument placed in your car that helps in monitoring the air pressure in your tyres and alerts you when it drops dangerously low. Both over- and under-inflation of tires can result in premature treadwear and tire failure in the worst-case scenario.

Overinflation can result in poor traction, premature tire wear, and an inability to absorb impact from the road. On the other hand, underinflation results in sluggish tire reaction, lower fuel economy, excess heat buildup, and tire overload, all of which can result in dangerous driving circumstances. 

Once your tires inflate, the tire pressure light should turn off automatically. If it remains for an extended period, you may need to reset the service tire monitor system.

You may correctly reset it by updating the sensors and inflating and deflating it. I hope this article addressed all of your concerns regarding How to Reset Service Tire Monitor System?
