Tyre Pressure Monitoring Systems

Ideally, the only time a sensor should need to be replaced is when the internal battery runs flat. However, due to environmental weathering and sometimes galvanic corrosion of some of the components fastening the valve to your wheel and sealing the valve airtight, TPMS valves can become faulty or fail completely. A simple and considerably cheaper solution is to keep the valve in good condition through servicing, replacing the old components with a brand new set.

Servicing of TPMS Sensors every time the tyre bead is broken is considered a standard requirement by sensor manufacturers in order for them to last a full lifetime.

Ideally, sensors generally require replacement once the internal battery has died. The battery life of each sensor can be anything between 3 & 7 years or around 100k-150k miles. The internal battery of a sensor is used all the time at some level, with minimal use whilst the vehicle is stationary, moderate use when the vehicle is moving, and heavy use if the TPMS system is in alert mode due to low tyre pressure or puncture detection (warning light on dashboard). Unfortunately, due to incorrect handling or neglect of servicing, sensors and sensor components can also break, which in some cases may require a complete sensor replacement. When TPMS sensors are replaced an electronic reset is required.

When new sensors are fitted to a vehicle they must be paired to the ECU (the car’s computer) in order for them to work, and to clear the warning lights from the vehicle’s dash, at Cheadle Tyre & Auto we have state-of-the-art equipment to check the TPMS, correct any faults and reset the ECU of any vehicle.
