Service Tire Motor System Chevy: What Does It Mean?

Service tire monitor system Chevy is a common mystery among Chevy owners. Under- or over-inflated tires will not function well, and drivers may encounter poor grip on the road, poor fuel efficiency, a flat tire, or even a tire blowout.

Service Tire Motor System

Most contemporary automobiles come equipped with service tire monitoring devices to assist drivers in maintaining proper tire pressure. This guide explains everything you need about your Chevy tire motor system.

What Is the Meaning of a Tire Monitor Pressure System?

The meaning of a tire monitor pressure system is that there’s an issue with your system caused by a system issue, a dead battery in a tire sensor, a sensor failure, or a sensor that requires recalibrating with the vehicle’s computer.

The “Service Tire Monitor System” notice does not necessarily indicate that one or more of your tires are flat. It’s time to act and look into your Chevy if the “Service Tire Monitor System” notification appears.

Drivers won’t be able to precisely check their tires’ pressure when there is a TPMS issue with their car. Of course, a tire pressure gauge may be used to check the psi, but a TPMS sensor automates the process and makes it much simpler for drivers to remain on top of.

What Is Chevy’s TPMS?

Chevy’s TPMS is a system that helps to manage your vehicle’s tires’ air pressure. The air pressure is monitored by sensors fastened to the inside of the rim. When the sensors detect a low tire pressure, radio signals are transferred to the receiver turning on the TPMS light.

For the tire sensors to promptly warn drivers of a rapid loss in air pressure, they must be in continual communication with the computer in your car. The TPMS earning on the dashboard appears like a horseshoe with an exclamation point. Drivers must check their vehicle’s settings for the TPMS menu when this light illuminates to determine which tire or tires need to be inflated.

If the TPMS flashes on and off, it signals that one or more of the tires are losing air, and you should check the tire pressure and replenish the air. If the light remains on, it may mean that the tires need to be inflated immediately because they may have lost up to 25 percent of their recommended air pressure.

What Are the Possible Causes of TPMS Light On?

The possible causes of the TPMS light on are that the sensor battery is dead, there is a defective tire sensor, the new sensor needs calibration, or old sensors haven’t been recalibrated.

Causes of TPMS Light On

So when you notice your TPMS warning light is on, check for any symptoms.

Not Recalibrating Old Sensors

After a tire rotation, some older vehicles with outdated TPMS require recalibrating the sensors. The signals will only be picked up correctly if the sensors are recalibrated to their new location. Drivers will only be aware of the tire’s pressure if the car’s sensors are providing reliable information, which will cause the service notification to display.

Dead Tire Sensor Battery

The TPMS sends radio signals from sensors mounted on the tires back to the computer in the vehicle. The TPMS light will turn on on the dashboard if a tire is low due to the sensors continuously monitoring the tire’s air pressure. Each sensor has a lithium-ion battery, which should last about five years.

Faulty Tire Sensor

The car’s computer won’t get reliable information regarding tire pressure if one of the sensors’ batteries dies. The other batteries will likely run out of juice if one fails. Driving without knowing your tire pressure can result in a dangerous blowout and an undiscovered flat.

Uncalibrated New Sensor

The Service Tire Monitor System alert could appear if new sensors are installed without first calibrating using the TPMS tool. Some cars must be put into a learning mode to recalibrate the new sensors with the car’s computer. Your automobile needs to know which sensor is connected to which tire to monitor and show the pressure data properly.

Faulty Tire Sensor

The tire sensors can still be to blame even though the battery might not be dead. Tire sensors that have been damaged due to tire sealant being inserted into the stem valve may no longer be able to produce steady signals, which will cause the service notice to appear. The tire pressure sensor may also be harmed by corrosion at the tire stem and nearby.

What Are the Possible Solutions for TPMS Light On?

The possible solutions for TPMS light on are to fix your dead sensor battery, repair your tire sensor, calibrate your new tire sensors, and recalibrate your old tire sensors. You can choose to do all these yourself or employ the services of a professional.

Calibrate New Sensor

To calibrate a new sensor, first, gimme the engine on and leave it on for a while. The car’s computer menu can be accessed using the toggle or buttons to find the tire pressure information. There might be a ‘Relearn Tire Position’ option; choose it. Press LOCK and UNLOCK simultaneously on the key fob to proceed.

Wait for the horn to blow twice, at this point, you can recalibrate the sensors; you should see the digital display “TIRE LEARN ACTIVE.” Turn the automatic headlights off if your car has them. This will activate the marker light on the left front tire, meaning the left front sensor will be calibrated first. Point a GM TPMS relearn tool at the left front tire while depressing the RESET button.

When the horn blows, the sensor has been properly configured. Now the marker light on the left front tire will go off. Repeat the steps in the previous section, resetting each new sensor in the proper order as you follow the lights. Once the last tire sensor has been reset, the horn will ring twice more to inform you that the recalibration process is complete.

Repair Your Tire Sensor

Once more, there is a very straightforward solution to this issue. If it is damaged, one of your sensors should be replaced as soon as possible. If the problem is not a battery problem, you should be able to replace the damaged sensor and leave the others alone.

However, you can have all four sensors replaced at once if you want even wear on your car’s components.

Fix Your Dead Sensor

You only need to swap out the sensor with a dead battery to resolve this TPMS issue. If you have the funds, try to replace all the sensors when one goes flat. However, the batteries on the Chevy TPMS sensors are integrated and cannot be changed, necessitating the replacement of the entire sensor.

If one of the batteries in your Service Tire Monitor System is dead, the other three are most likely not far after. For detailed instructions on how to replace that flat battery, see the video below.

Seek Professional Help

If you have tried the above solutions and the “Service Tire Monitor System” notice still won’t go away, you may need to visit the mechanic.

A qualified individual can perform a diagnostic test and identify the precise fault code. The most frequent cause of this message to appear is a flat sensor battery, but it might also be due to any problems with the TPMS, so it is recommended to have them fixed as soon as possible.

What’s the Standard PSI for Chevrolet Tires?

The standard PSI for Chevrolet tires is 35. The TPMS assists drivers in keeping track of the pressure in the tire. Driving on a flat tire can put other road users in grave danger. There are various problems associated with tires that have lost air pressure.

The tire will lose grip on the road, your car may veer to one side, and the tire could even blow out. It’s crucial to fill the tire back up immediately if your TPMS light is on and alerting you that one or more of the tires are underinflated. Your owner’s manual or the door jam placard will have the tire information.

It is essential that you are aware of the precise air pressure that your car’s tires require. As dangerous as letting tires deflate can be is overinflation. By ensuring your TPMS is operating correctly and filling the tires as soon as the TPMS signal illuminates, you can maintain the ideal air pressure in your tires.

Can You Drive With TPMS Displayed?

Yes, you can drive with TPMS displayed, and it simply means there’s an issue with your tire pressure monitoring system if it’s on. However, because you can drive with the tire pressure message system light on does not mean you should ignore it.
