Tyre Pressure Monitoring System 101 – Getting Familiar with the Digital Way

The automobile industry is probably one of the fastest growing sectors in the world today. Think about it; remember the car that you learned driving on? Were there any fancy bells and whistles to take care of its engine output, exhaust emission, tyre pressure etc.? Those cars were bare-bone with only the minimum components needed to run them properly.

Then again, deadly accidents were more common with those vehicles.

Almost every car owner will agree that these new ‘gadgets’ offer a much safer commute every time you start your vehicle. Now, it is impossible to talk about every single one of them in this blog, so, let’s concentrate on one of the most common, and critical sensors in your vehicle – the Tyre Pressure Monitoring System.

What is a Tyre Pressure Monitoring System?

A Tyre Pressure Monitoring System, or TPMS, is a tiny sensor rooted inside the tyre valve that continuously monitors your car’s tyre pressure. Whenever it drops below a pre-set danger level, you will see a tiny indicator on your dashboard warning you about the condition.

Before this automatic system was introduced, a tyre pressure check meant kneeling down beside your car and measuring each tyre’s pressure with a gauge. TPMS was first introduced in the 1980’s in luxury cars, and by 1986, it was available in passenger cars in Europe.

Following a number of accidents due to underinflated tyres both in the US and the UK,the Government took a step to include some kind of TPMS in every single vehicle.

So, there are different types of systems available?

There are two main types of TPMS out there, and your car will have any one of them. Both systems have some advantages and disadvantages. However, no matter where you are, car garages from Wolverhampton to London will advise you to make sure they are working all the time.

The two different types of systems are –

  1. Indirect TPMS – It monitors the tyre pressure with the ABS unit and the car’s ECU. It measures your car tyres revolution and calculates how much air is inside. For example, if your car wheel is spinning too fast, chances are it is underinflated.

This system is cheaper and less maintenance intensive. However, it is also more prone to malfunction. The moment you use a smaller (or larger) tyre, it will start showing incorrect data. You also need to reset it after rotating the tyres or re-inflating them.

  1. Direct TPMS –This type uses a dedicated pressure sensor unit to measure your car’s tyre pressure. This system does not depend on any other sensor to learn about the condition of the tyres. This makes them extremely accurate and versatile. Some more expensive systems can even measure the temperature of your car tyres.

However, remember to mount or dismount wheels with direct TPMS carefully.These can get easily damaged. It is best if you take your car to a reputed service garage like Car Tyres Wolverhampton; a professional technician will know how to handle such a delicate sensor properly.

How TPMS has changed the scenario

That tiny TPMS light on your car’s dash is the result of hundreds of years of uncertainty and risk associated with underinflated car tyres. The TPMS was a revolution that made the streets around the world a lot safer. The technology may be different, but both the system give a driver that much needed heads up when they are on the verge of losing control over their car due to underinflated tyres.
