TPMS Tyre Pressure Monitor System
Know what to do when this symbol lights up on your dashboard?
This means your vehicle has some form of TPMS (Tyre Pressure Monitor System)
What is TPMS?
TMPS or Tyre Pressure Montior System is a system that monitors your vehicles tyre pressures. As of November 2014 all new passenger vehicles must have TPMS fitted to them by law. Any vehicle that is registered after January 2012 that has TPMS must have it fully working as it is now part of the MOT test. Any TPMS that is not working correctly, a sensor fault, light on the dashboard or replaced a TPMS valve with a ordinary rubber valve faces instant failure.
How can we help?
We now have the full TPMS diagnostic equipment with spare sensors,service kits and online support to keep your TPMS system in proper working condtion. We have the ability to service the valve or replace complete sensors with Original Equipment or sometimes less expensive after market sensors.
Direct and Indirect TPMS Systems
Depending on which vehicle you own or drive your vehicle could have direct or indirect TPMS. There are advantages and disadvantages with both systems
A direct system has a sensor valve fitted inside each wheel.
Disadvantages of Direct system
More expensive overall than an indirect TPMS
Though simple, resynchronization may require costly tools.
Battery rarely serviceable; if the battery is drained, the whole sensor must be changed.
Proprietary systems make installation, service, and replacement confusing for consumers and auto shops.
Sensors are susceptible to damage during mounting/demounting
An indirect system uses the wheel speed sensors that the anti-lock brake system uses
Disadvantages of Indirect system
May become inaccurate if you purchase a bigger or smaller tyre
May be unreliable when tyres are unevenly worn
Must be reset after properly inflating every tyre
Must be reset after routine tyre rotation
TPMS Facts & Figures
Data analysis shows that a new tyre will leak 3psi - 8psi over a year which results in around a 2% increase in fuel consumption and a 25% reduction in tyre life.
The EU estimates that the under-inflation of tyres is globally responsible each year for:
• 20 million litres of unnecessary fuel consumed
• 2 million tonnes of CO2 emissions
• 200 million prematurely worn tyres
• 9% of accidents involving fatalities
• 41% of accidents involving injury
