How do TPMS Sensors Work?

Every sensor has a unique identification that it transmits to a receiver via wireless remote frequency at 433 MHz (euro standard). The receiver then transmits the data to the controller allowing the information to display to the driver.
They are powered by an internal battery; this battery cannot be replaced. The battery life is expected to last up to 5-7 years’ dependent on annual mileage. To save energy the sensor doesn’t transmit data unless it is rotating, which also prevents the spare tyre from being monitored.  With every transmission of data, the sensor will also send a battery state signal, which workshop tools can use to diagnose a low battery

What If My TPMS Sensor Needs Replacing?

If the TPMS warning light is illuminated on your vehicle’s dashboard it will usually indicate a pressure drop in one or more of the vehicle’s tyres & needs immediate attention, however if the light is on due to sensor malfunction, usually due to battery failure, or physical damage, then the sensor will require replacement, use our vehicle search facility or contact one of our team for help finding the correct replacement.
Installing the replacement sensor will require tyre removal by a professional tyre fitter, the old sensor removing and the replacement sensor fitting correctly to the manufacturer’s specifications.
After fitting the sensor will require pairing with your car, the pairing procedure can usually be found in the vehicles handbook alternatively use our vehicle lookup or call a member of staff. The relearn procedure may be as simple as driving the car for a few miles, alternatively your vehicle may require dealer level programming and will incur additional installation costs, however this cost can be avoided by cloning the replacement sensor to the old sensor thus creating an exact copy, usually all we need is a number printed on your old sensor so don’t throw it away just yet, cloning would be done prior to shipping ask one of our team for details.
