OUR TPMS REPAIR SERVICES
From sensor inspections to TPMS replacement, Firestone Complete Auto care offers a wide range of services to keep your tire pressure monitoring system working like it should. Our expert technicians are here to help you stay safe on the road with reliable TPMS care.
WHAT HAPPENS DURING TPMS REPAIR SERVICE?
- WHAT WE DO: Inspect your tire pressure monitoring system (TPMS) and perform repairs as needed, including diagnosing issues and repairing or replacing faulty sensors to help restore accurate tire pressure readings.
- WHAT QUALIFIES: A TPMS warning light, inaccurate readings, a broken TPMS sensor, or issues after tire service may indicate the need for tire pressure monitoring system repair.
- WHAT DOESN’T QUALIFY: Damaged tires, tire air leaks, or wheel issues may require tire repair or replacement in addition to TPMS service.
- INCLUDED CHECKS: We check TPMS sensors, system communication, and tire pressure levels. TPMS sensor repair or replacement may be recommended if a sensor is not functioning properly.
- AVERAGE SERVICE TIME: Many TPMS diagnostics and repairs can be completed in about 30–60 minutes, depending on the issue and parts required.
- SERVICE INTERVAL: TPMS service isn’t required at set intervals. It’s recommended anytime the TPMS warning light comes on, after tire replacement or rotation.
HOW YOUR VEHICLE MAINTENANCE SERVICE WORKS
Frequently Asked Questions
PSI (pounds per square inch) is a unit of measurement used to determine recommended tire pressure levels. Your vehicle’s recommended PSI is listed in the owner’s manual as well as on a sticker located on the door jamb, glove box door, fuel door, or spare tire. These numbers reflect the PSI needed for proper load support and safe handling. Many vehicles also require different levels for the front and rear tires, so use a tire pressure gauge to adjust as needed.
Tire pressure shifts with temperature because air contracts in the cold and expands in the heat, so it’s important to check pressure during weather changes. Tires typically lose or gain 1 to 2 PSI for every 10 degrees Fahrenheit, which means a sudden cold snap or warm spell can change levels by several PSI. Cold weather may also cause temporary drops that return once temperatures rise, while hot weather can increase PSI throughout the day.
A tire pressure monitoring system (TPMS) alerts you when a tire is significantly underinflated, using either direct sensors inside each tire or indirect readings from the anti-lock braking system (ABS) wheel-speed system. When pressure drops below the recommended PSI, the TPMS light appears on the dashboard, typically as a yellow horseshoe-shaped tire with an exclamation point. Some vehicles may also display an icon identifying which tire is low. If the light stays on, confirm pressure with a gauge and inflate the affected tire to the recommended PSI. Persistent warnings may indicate a puncture, slow leak, or sensor issue that requires diagnostic testing.
Checking and filling your tires starts with finding the recommended PSI on the driver’s door jamb or in the owner’s manual. Then, use a tire pressure gauge to get an accurate reading. Remove the valve stem cap, press the gauge firmly onto the valve, and compare the reading to the cold tire specification. If pressure is low, add air at a gas station or with a home compressor in short bursts, checking frequently to avoid overinflating. Release excess air if needed, then replace the valve caps once all tires reach the proper level. If you need assistance with filling tires, make an appointment at your nearest Firestone Complete Auto Care for in-person guidance.
Incorrect tire pressure can affect fuel economy, handling, braking, and tire lifespan. Underinflated tires create more surface contact with the road, which can make the vehicle feel less responsive and reduce fuel efficiency. The U.S. Department of Energy reports that gas mileage can drop by about 0.2 percent for every 1 PSI decrease in average pressure. Underinflation also accelerates wear and increases the risk of damage. Overinflated tires have less road contact, which can lead to uneven wear, reduced braking performance, and greater susceptibility to potholes or debris. Regular gauge checks help keep tires at the recommended PSI for safe operation.
