Most tire pressure sensors, part of the Tire Pressure Monitoring System (TPMS), have non-replaceable batteries. These built-in batteries last around 5 to 10 years. When they fail, you must replace the whole sensor. Regular maintenance is essential for monitoring low tire pressure, ensuring optimal tire performance and vehicle safety.
The cost to replace tire pressure sensor batteries generally ranges from $50 to $150 per sensor. This price includes labor, as sensors often require reprogramming to ensure proper function. The battery replacement process typically involves removing the tire from the wheel, extracting the sensor, and replacing the battery. Proper handling is essential to avoid damaging the sensor.
To extend the life of your tire pressure sensors, maintain correct tire pressure and perform regular inspections. If you notice a tire pressure warning light, check the sensors for proper function to determine if battery replacement is necessary.
In summary, while tire pressure sensor batteries can be replaced, the cost and process may vary. Understanding when to replace them can help maintain vehicle safety. Next, we will explore how to identify signs of failing tire pressure sensors.
Can Tire Pressure Sensor Batteries Be Replaced?
No, tire pressure sensor batteries cannot typically be replaced. The sensors are designed as sealed units.
Most tire pressure monitoring systems (TPMS) use sensors built into the tire that monitor air pressure. When the battery in a sensor depletes, the entire sensor must often be replaced. This is because the sensors are often not designed for battery replacement, and doing so can compromise the unit’s integrity. Some manufacturers might allow for battery replacement in certain models, but generally, it’s more common to replace the entire sensor for consistent functionality.
Which Tire Pressure Sensors Allow for Battery Replacement?
Certain tire pressure sensors allow for battery replacement. Not all tire pressure monitoring systems (TPMS) offer this feature, however.
- Types of TPMS that allow battery replacement:
