Stumped by TPMS? Finally an Explanation of How TPMS Works!

There is nothing wrong in admitting you have no idea how Tyre Pressure Monitoring Systems work – you’re not the only one! It’s a technology on the rise and many can’t afford to ignore it any longer.

TPMS Recap

As you will know, TPMS Sensors provide real-time data and live feedback on the dashboard to a vehicle’s driver – giving warnings, air pressure readings and recommended actions among other feedback. They truly are a revolutionary tool for modern driver safety.

The electronic valve system has been designed as a legal requirement that must be installed on all vehicles manufactured from 2014 onwards.

Direct or Indirect Types of TPMS

TPMS can function within a vehicle in one of two ways. Directly or indirectly.

Hybrid 3.5 New TPMS Sensors

Direct

Direct TPMS uses a mounted sensor inside each of the wheels to monitor the air pressure. The sensor will then send an alert to the driver’s dashboard. Usually a light or warning sign will appear if the air pressure drops below a critical point (generally 25% of the normal tyre pressure).

Indirect

Indirect TPMS monitors measure pressure through the wheel speed sensors, usually found on the anti lock braking system (ABS). If one wheel is spinning at a different RPM to others it is likely that tyre’s pressure is low. Feedback is again sent to the driver’s dashboard.

General wear and tear can occur over time, with each TPMS sensor degrading or being damaged – leading to them needing replacement.

After replacing a TPMS sensor for a brand new one, it has to be reprogrammed via a TPMS diagnostic tool for the specific vehicle make and model. This enables the sensor to talk to the vehicle and send accurate readings.

TPMS: What are the most common Tyre Pressure Monitoring System issues?

A delicate TPMS sensor placed in the wheel to report on the performance of each tyre. It could be seen as daft putting such a delicate sensor within a tyre, somewhere that is under constant pressure and strain whilst the vehicle is moving. But in actual fact, these sensors are tough and provide vital information on the performance of our tyres.

That’s not to say that they are invincible though!

Just like any other area of a vehicle, TPMS sensors can get damaged or disconnected at any point in time; a car accident, a MASSIVE pothole…the list is bigger than you might think. Therefore, being able to identify the exact issue with a customer’s vehicle is paramount, to ensure their car is safe to drive and to provide the service they deserve.

What could be the problem with a TPMS sensor?

A major indication that there is an issue with your TPMS sensors, is when the TPMS status warning light becomes visible on your vehicle’s dashboard and constantly remains illuminated.

If this persists, a thorough check of the system is needed at a reputable tyre shop to diagnose the exact problem:

  • Lost TPMS signals
  • Damaged or shorted antenna on a wheel
  • Faulty wiring between the antenna & the TPMS module
  • EMI (Electro Magnetic Interference)
  • Integration failure – Malfunctioning key-less entry system
  • Improper relearn procedure – Post installation of a brand new tyre

These are just a handful of the most common TPMS issues and can be fully identified with the right TPMS Diagnostic Tool.
