Is your tire pressure light on even though your tires look fine?
Your vehicle's Tire Pressure Monitoring System, commonly called TPMS, is designed to alert you when tire pressure requires attention. But a TPMS warning doesn't always mean you simply need to add air.
Sometimes the tire is low because of a leak. Other times, the TPMS sensor or monitoring system itself may have a problem.
At KG Automotive Solutions in Fitzwilliam, NH, we provide tire pressure checks, TPMS diagnosis, TPMS sensor replacement, and related tire service for cars, trucks, and SUVs.
We serve drivers throughout Fitzwilliam, Rindge, Jaffrey, Troy, Swanzey, communities throughout Cheshire County, NH, and the Winchendon, MA area.
What Is TPMS?
TPMS stands for Tire Pressure Monitoring System.
The system monitors tire pressure and alerts the driver when it detects a condition that requires attention.
Depending on the vehicle, TPMS may use pressure sensors located at the wheels or another monitoring strategy to detect changes in tire pressure.
When the system detects a problem, a warning indicator appears on the dashboard.
That warning is useful—but it doesn't necessarily tell you why the warning came on.
Why Is My TPMS Light On?
One of the most common reasons for a TPMS warning is simply a tire that's low on air.
But that's not the only possibility.
A TPMS warning may be related to:
- Low tire pressure
- A tire puncture or slow leak
- Temperature changes
- A leaking valve stem
- A damaged or failed TPMS sensor
- A sensor battery reaching the end of its life
- A sensor that needs to be relearned or programmed
- A wheel or tire that has recently been serviced
- Another TPMS-related problem
Instead of simply turning the light off, we want to determine why it came on.
Cold Weather & Your TPMS Light
If your TPMS light seems to appear every fall or winter, you're not imagining it.
As outside temperatures drop, tire pressure typically drops as well.
That's especially noticeable here in New Hampshire, where significant temperature changes can happen quickly.
A tire that was properly inflated during warmer weather may trigger the TPMS warning after temperatures fall.
Sometimes correcting the tire pressure is all that's needed.
But if one tire repeatedly loses more pressure than the others, there may be a leak that deserves attention.
What If My Tire Keeps Losing Air?
If you're repeatedly adding air to the same tire, the air is going somewhere.
Possible causes can include:
- Nail, screw, or other puncture
- Valve-stem leak
- Wheel or bead-area leak
- Tire damage
- Other air-loss concerns
Adding air may temporarily turn off the warning, but it doesn't repair the reason the tire became low.
We'll evaluate the tire and help determine the appropriate repair.
TPMS Sensor Replacement
TPMS sensors don't necessarily last forever.
On many vehicles, direct TPMS sensors contain internal batteries. Eventually, those batteries can fail, requiring sensor replacement.
Sensors can also be damaged during tire or wheel service or develop other problems over time.
If testing indicates that a TPMS sensor has failed, we can determine the appropriate replacement for your vehicle.
Depending on the vehicle and system, a replacement sensor may also require programming or a relearn procedure so the vehicle recognizes it properly.
TPMS Programming & Relearn
Replacing a TPMS sensor isn't always as simple as installing the part and driving away.
Different vehicles use different procedures for recognizing and communicating with their tire-pressure sensors.
Depending on the application, a sensor may require:
- Programming
- Relearn procedure
- Sensor identification
- Vehicle-specific initialization
- Driving procedure after service
We'll follow the appropriate procedure for the vehicle and TPMS system we're servicing.
TPMS Light vs. TPMS System Malfunction
How the warning behaves can sometimes provide useful information.
A warning caused by low tire pressure may behave differently from a warning indicating a malfunction within the TPMS system.
The exact behavior varies by vehicle, so we don't recommend diagnosing the problem based solely on what the dashboard light is doing.
If you're unsure, bring the vehicle in and we'll help determine whether you're dealing with a tire-pressure problem, tire leak, sensor problem, or another TPMS concern.
Proper Tire Pressure Still Matters
TPMS is a warning system—not a replacement for proper tire maintenance.
Correct tire pressure is important for:
- Tire wear
- Handling
- Braking performance
- Ride quality
- Fuel efficiency
- Overall tire performance
Overinflation can create problems too, which is why simply adding extra air isn't the answer.
Tires should be inflated to the appropriate pressure for the vehicle and application.
Don't Rely on the Number Printed on the Tire
One common mistake is inflating tires based on the maximum pressure printed on the tire's sidewall.
That number is not necessarily the recommended operating pressure for your vehicle.
The vehicle manufacturer's tire-pressure specification is generally found on the tire information placard, commonly located around the driver's door or door jamb.
If you're unsure what pressure your tires should be set to, we can help.
TPMS Service During Tire Replacement
Tire replacement gives us an opportunity to evaluate TPMS-related components while the tires are being serviced.
If we identify a sensor or related component that needs attention, we'll explain what we're seeing and discuss your options.
We don't automatically replace every TPMS sensor simply because you're purchasing tires.
Our recommendation will depend on the vehicle, sensor condition, age, and circumstances of the service.
Every Service Visit Includes a Digital Vehicle Inspection
Every service visit at KG Automotive Solutions includes a Digital Vehicle Inspection at no additional charge.
During your visit, our technicians evaluate visible conditions throughout the vehicle, including tires and other accessible components.
If we notice unusual tire wear, low tire pressure, visible tire damage, or another concern, we'll document what we're seeing and communicate it with you.
That helps you understand what needs attention now, what can be planned for later, and what should simply be monitored.
