When you acquire a new or a low-mileage vehicle and imbibe regular car maintenance, you often think you are immune to car problems. The truth is cars develop problems even when we least expect them.
It’s okay to panic or worry when a warning message pops up in the driver’s information center.
Car manufacturers install several car sensors on a car’s interior and exterior parts, which monitor and notify you when a problem exists. Some warning messages may be strange, and we may not understand them.
No doubt, we all know that the illumination of the check engine light signifies an underlying issue in one or several system components. But what about other warning messages like the service tire monitor system?
What Is a Tire Monitor System?
A Tire Pressure Monitoring System (TPMS) is an electronic system that measures air pressure in each tire.
It notifies the driver if the tire pressure drops below the recommended level, ensuring safe driving conditions. Proper tire pressure is crucial for fuel efficiency, tire longevity, and safety on the road.
Without a functioning TPMS, you could miss slow air leaks—raising the risk of tire blowouts or unstable handling. That’s why services like ECU programming in Erlanger, KY, can play a role in keeping systems in sync.
What does it mean when it says Service tire monitor system?
When a service tire monitor system light pops up on the dashboard, it means you have issues related to TPMS caused by a tire sensor failure, flat sensor battery, or a sensor that needs reprogramming.
The tire monitor system will activate on some vehicles when your car tires are low. You’ll have a service tire monitor system light blinking on the dashboard, or an error message will display on the dashboard, telling you what’s wrong.
Depending on your car model, the service tire monitor system may even tell you the amount of air pressure on each tire.
Usually, the light will appear and disappear shortly if you have low tire pressure. However, if the warning light stays lit, you have a severe issue that needs urgent attention.
Is Service Tire Monitoring System Important?
Yes. It is crucial for various reasons in addition to letting you know that your TPMS needs to be serviced.
Tire pressure may be below ideal levels or dropped to suboptimal levels when the alert is visible. The tires themselves may also be damaged and unable to keep the correct pressure. This can lead to the following issues:
- Lower fuel efficiency
- Reduced vehicle handling capabilities
- Less payload capacity
- Potential blowout or flat tire
How the Tire Pressure Monitoring System Works?
The TPMS operates through two distinct technologies that monitor tire conditions using different measurement approaches. Both systems provide crucial safety data to drivers through dashboard alerts when tire pressure drops below recommended levels.
Direct TPMS Technology
Direct TPMS employs pressure sensors mounted inside each tire to measure actual air pressure readings.
These sensors transmit real-time data wirelessly to a central control module that processes the information and displays warnings on the dashboard. Each sensor contains a battery that typically lasts 5-10 years before requiring replacement.
The system delivers precise pressure measurements in pounds per square inch (PSI) rather than estimated values. Direct TPMS sensors also monitor tire temperature alongside pressure readings to provide comprehensive tire health data.
Installation requires specialized equipment to mount sensors inside the tire during mounting or remounting procedures.
Calibration occurs automatically when sensors communicate with the vehicle’s computer system during normal driving conditions. The technology maintains accuracy regardless of tire rotations or replacements since each sensor has a unique identification code.
Direct systems cost more initially but provide superior monitoring capabilities compared to indirect alternatives.
Indirect TPMS Technology
Indirect TPMS monitors tire pressure through wheel speed sensors that connect to the anti-lock braking system rather than using dedicated pressure sensors.
The system detects pressure loss by analyzing rotational speed differences between tires since underinflated tires rotate faster than properly inflated ones.
Wheel speed data flows from existing ABS sensors to the TPMS control module for analysis. The system calculates pressure estimates based on comparative wheel speeds and alerts drivers when important variations occur.
Indirect systems require manual recalibration after tire rotations service or pressure adjustments to maintain accuracy.
Cost advantages make indirect TPMS attractive for vehicle manufacturers since it uses existing ABS infrastructure. The technology works effectively for detecting gradual pressure loss but may not identify simultaneous pressure drops in multiple tires.
Indirect systems also struggle with accuracy when different tire brands or sizes are mixed on the same vehicle.
causes of a service tire monitor system
Here are other probable causes of a service tire monitor system on Chevy Malibu and other car models.
#1. Damaged tire sensor monitor.
Every car sensor plays a specific role. For instance, the tire sensor monitors the air pressure in the tire. If the car tire sensor fails, It will not send a consistent signal to the car computer concerning the tire pressure.
The sensor can fail for various reasons, most likely due to sealant on the stem valves. Other reasons include corrosion in and around the TPMS.
#2. Dead tire monitor sensor battery.
The TPMS has a radio signal sensor mounted on the tire rim. This sensor monitors the tire air pressure. Once it detects low pressure, it will ignite the service tire monitor system on the Chevy dashboard or your respective car model.
Each tire pressure monitor sensor has a Lithium-ion battery that should last around five years. Once the battery runs out of juice, the sensor will not communicate with the powertrain control module about the air pressure in your tire.
If the car computer does not receive any signal from the TMPS, you may project a service tire monitor system on Chevy Silverado or your respective car model.
#3. New tires that need calibration.
Some vehicles require you to calibrate the tire pressure monitor after installing a new one. So it’s okay if the service tire monitor system warning appears on your dashboard after installing a new sensor. You only need to calibrate the sensor.
How do I fix my service tire monitor?
