Benefits of TPMS
The performance and behaviour of any pneumatic tyre is directly related to its inflation pressure. Stability, braking and wet weather handling are key factors affected when pressures deviate from those specified by the manufacturer. Tyres will leak air naturally – even when new and properly mounted.
Fuel efficiency and tyre wear are severely affected by tyre pressure and it is commonly understood that for every 10% of under-inflation, there will be a 2% reduction in fuel economy! Big numbers with the current price of fuel!
For safety, correct tyre pressures add greater overall vehicle stability, handling and braking efficiency – protecting not just the driver and passengers but other road users too.
We replace faulty, damaged or aged TPMS sensors, This includes (where applicable) removal and replacement of just the stems rather than the entire sensor unit. Our systems allow for cost effective cloning and reprogramming of generic sensors with either solid or rubber stems to suit the application vehicle. All of this at a fraction of the price you would inevitably pay at a main agent!
Why do TPMS Sensors need to be replaced?
In ideal running conditions TPMS sensors generally only require replacement once the internal battery has failed. This can be anything between 3-7 years depending on the amount of information they are transmitting. The battery within a sensor is in use at all times but varies the amount of information it is sending to the vehicle. Whilst stationary the information and battery usage is a lot lower than when a pressure has dropped below the set limit and the sensor is feeding constant information to the vehicle.
Along with batteries causing problems, neglect and incorrect handling can also be a cause for a sensor to need to be replaced. Some sensors have replaceable parts but unfortunately some don’t which will often mean a whole new unit will need to be fitted.
Why do TPMS Sensors need Servicing?
Tyre pressure monitoring valves are relatively expensive items in a wheel and tyre assembly with some costing well over the €250.00 mark for a direct OE replacement. Thankfully they don’t need to be changed all that often but they should be serviced and have damaged or worn/degrading parts replaced ASAP when needed to prolong their life.
Valve Stems can become damaged through normal wear and tear, corrosion and through over-tightening of valve caps and the locking hex nuts which hold the valve assembly in place within the wheel. A stem failure could cause a rapid loss of tyre pressure leading to the potential not just of the tyre replacement but of subsequent damage to the electronic sensor too.
Will the new sensor need an electronic reset?
When new sensors are fitted to a vehicle it is important that they are able to communicate properly with the vehicle’s onboard computer (ECU). This is also needed if wheels are moved around a car to a different location. In order for the system to idenitfy to the driver which wheel/tyre is causing an alarm, the ECU must have correct location identification stored.
A number of vehicles have an ‘automated self-learning’ sequence where this information is automatically updated to the ECU. Others require a physical reprogramming between the sensors and the onboard computer – previously often only able to be carried out at significant expense at the manufacturers dealership site.
