A steady tire pressure warning light usually means one or more tires are underinflated, while a flashing light often indicates a system malfunction or a sensor issue.
When your tire pressure monitoring system (TPMS) light illuminates, it's important to assess the situation promptly. A steady light suggests you should immediately check your tire inflation levels and add air if necessary. If the light continues to stay on after inflating the tires to the recommended pressure, or if it flashes, it could signal a problem with the TPMS sensors themselves or another component of the system. Driving with underinflated tires can lead to poor handling, increased fuel consumption, and accelerated tire wear. A flashing light, in particular, warrants a closer inspection by a professional to diagnose the specific issue.
This information is for general guidance; always consult your vehicle's owner's manual and a qualified mechanic for specific diagnoses and repairs.
What is the average cost to replace a TPMS sensor?
The average cost to replace a TPMS sensor can range from $50 to $150 per sensor, with the total cost depending on the vehicle make and model, the type of sensor used (OEM vs. aftermarket), and labor rates in your area. This price typically includes the cost of the sensor itself and the labor to install and program it. Some vehicles may require a special diagnostic tool to program the new sensor to the car's computer, which can add to the overall expense. It's advisable to get a quote from a few different reputable repair shops.
