What's the difference between indirect TPMS and direct TPMS?
Indirect TPMS relies on the vehicle's ABS to measure individual wheel rotation speeds to report tyre pressure readings. low tyre pressure is detected by comparing relative wheel speeds via the Anti-lock Brake System (ABS) wheel speed sensors. When a tyre loses air, its diameter decreases slightly. Direct TPMS utilises TPMS sensors, which sit inside the wheel to send pressure data to the vehicle's ECU wirelessly.
What are TPMS service kits?
Industry best practice is to always replace the wear items commonly found on most TPMS sensors. Most manufacturers recommend servicing a sensor each time the tyre bead is broken through repair or tyre replacement.
It is recommended that every time a tyre is taken off the wheel, these items should be replaced.
Replacing the TPMS service kit with regular tyre service will maximize the life of the TPMS sensor and prevent customer dissatisfaction due to leaks and flats.
Don’t forget that offering TPMS service kits protects your customer’s investment and represent a great opportunity to add revenue to your business.
Which part of a TPMS sensor needs servicing?
For Snap-In sensors its recommended to replace the Valve Cap, Nut Valve stem and Valve core Assembly as part of the service. For TPMS Clamp-in sensors replace the Screw, Vale Stem (Rubber Grommet and Valve Core Assembly), Collar/Nut and Washer and the Valve Cap. We supply a range of TPMS Service kits
that are compatible with most TPMS Sensor types.
A faulty TPMS sensor can now result in an immediate MOT failure. From the 1st January 2015 any car manufactured after 2012 that displays a TPMS warning light on will automatically fail its MOT test.
