How the Tire Pressure Monitoring System Works

If you are a regular car user, you must be aware of the importance of tire pressure for both its safety and performance. This is the reason why the automotive industry has developed a Tire Pressure Monitoring system, to make sure, you don’t have to manually struggle to maintain the recommended pressure for each of your vehicle tires.

If you are curious to have a deeper knowledge about how this system works, then here are some useful information for you that we got to know from the mechanics who serve at the center of Chevrolet tire rotation service near Pinehurst.

Built-in Components

The Tire Pressure Monitoring System is made of some major mechanical and electronic components that we are listing below:

Tire Pressure Monitoring System (TPMS) Sensor: The TPMS sensors work wirelessly and are responsible for transmitting protocol specific data to the vehicle along with the unique ID serial number of the model you are purchasing is required to identify the location of the tire. A replacement sensor plays the important role of matching the original protocol with that of the vehicle and needs to learn the ID of each new sensor added to the system.

Solid TPMS Light: it works as an indicator light, that stays on to let you know that it is required to check the tires and undergo proper inflation. It also alerts you regarding any damage caused to the tires.

Flashing TPMS Light: If the same TPMS light is flashing, it is the sign of a system failure or an impaired sensor that needs immediate diagnostics and care.

Signs of System Failure

Checking if the tire pressure monitoring system (TPMS) is fine is as easy a task as getting into the car and then turning on the ignition. The TPMS indicator speaks clear language through its lights. When the light turns off automatically after few seconds, know that the tire pressure monitoring system is in perfect tune, but if the light remains on even after a couple of minutes or starts flashing, it is a clear indication of an issue that demands immediate attention, and a professional hand for its repair. In most cases the tire pressure monitoring system fails, if its sensor gets damaged.

But if you are wondering what can cause damage to the TPMS sensor, then the answer isn’t so difficult. The TPMS sensor can get damaged due to several reasons like potholes, collisions, curbs, rough handling and severe off road driving jerks.

But the sensors work on batteries. So, is can also a greater probability of sensor battery failure which is neither serviceable nor replaceable. The usual lifespan of a sensor battery 7-10 years or over 100K miles. After crossing any of these milestones, the sensor battery will automatically become discharged and thereafter die. So, if your car is older than 10 years, you need to change the entire tire pressure monitoring system to get a new sensor, advised the senior most staff of the Pinehurst Chevrolet tire rotation service center.

Servicing of the TPMS Sensor

The TPMS sensor is consisted of a valve core, valve stem, washer, nut, seal, and cap that are one time usable items and they wear off over time. Manufacturers recommend to check all these TPMS sensor components whenever you go for a tire checkup and any damaged part should be immediately replaced to avoid a flat tire at the middle of your journey.
