Faulty tyre pressure monitoring systems could result in MOT fail

Faulty TPMS is resulting in motorists failing their MOT
If you have a Tyre Pressure Monitoring System (TPMS) then you might want to check it’s in full working order – otherwise you could be subject to failing your MOT.
With built-in pressure monitoring technology providing extra peace of mind for millions of UK motorists across the UK with TPMS now built into their wheels, it’s certainly an added advantage. But, as of 1 January this year, if your car has a fault with its TPMS when going in for an MOT then your test will result in a fail.
To ensure your TPMS system continues to operate properly and reduce the likelihood of an MOT failure, it may be necessary to have the system serviced occasionally. TPMS sensors are designed to last for many years and miles, however, after a certain period, the sensor’s internal battery will run out meaning a replacement is needed. Furthermore, your sensors can become faulty for any number of reasons including weather damage or being involved in a car accident, which is one of the reasons why manufacturers recommend that you replace the valve cap and core components every time a tyre is changed.
It’s also important to remember that just like with any technology it’s key to never rely too heavily on it. You should still regularly check your tyres manually to avoid any problems that your TPMS might not be alerting you of. The last thing you want is to have tyre issues with a caravan in tow causing a delay to your whole trip, as well as the possibility of a blow out, when it could have been easily avoided by checking the tyres beforehand.
To save you from a future MOT fail, check out the video below from UK tyre safety association, TyreSafe. They’ve produced a simple video to help you understand the safety features of TPMS allowing you to avoid any problems and ensure that the next time you take your car in for an MOT it will pass with flying colours.
