Typically TPMS sensors should last a great deal of time. However, some sensors can turn faulty, making the warning light flash on the drivers dashboard, even if the tyre pressure is correct (tyre pressure warning lights lit on the dashboard are now a failure on mot’s)
Also, if a tyre has been taken off the wheel or fitted incorrectly, it might cause the sensor to snap, resulting in needing a new sensor.
These are the only reasons you should need a sensor changing. St James Tyre Centre can change any sensor with ease. Usually we need 24 hours notice if you require a new sensor, this ensures that we can get you the right sensor and have it delivered to us within 24 hours.
