FAQ - Frequently Asked TPMS Sensor Questions

We answer your frequently asked questions regarding TPMS warning lights, sensors and replacements backed by our 25 years of customer feedback, experience and installations.

TPMS is a vehicle safety early warning system relating to abnormal tyre pressures in vehicles. Sensors and computers actively monitor tyre pressure underinflation, overinflation (Not All Vehicles) and TPMS sensor faults inside tyres.

TPMS sensors operate as a reliable third eye monitoring your vehicle tyre pressures from a perspective you can't see as a driver or passenger. 

How do I identify a TPMS warning light?

Above is the internationally recognisable TPMS warning light that illuminates on vehicle dashboards when TPMS tyre pressure and sensor issues are detected.

This TPMS warning light may flash, stay illuminated or be intermittent on/off depending on temperature, road and other safety related conditions.

How does TPMS work?

TPMS sensors are installed inside tyres and transmit valuable tyre pressure data to onboard computer systems ready to detect and alert you to potential vehicle safety concerns relating to tyre pressures.

Some vehicles use there ABS system, active suspension system or other sensors to actively monitor tyre pressures.

Why are TPMS systems important?

Tyre Pressure Monitoring Systems (TPMS) are important early warning systems in most modern vehicles for the following reasons;

Increase Safety: TPMS sensors alert you when tyre pressures are low which can prevent accidents caused by abnormal or under-inflated tyres. Correct tyre pressures improve driver and passenger safety, vehicle handling, reduce braking distances and decrease the likelihood of tyre blowouts.

Increase Fuel Efficiency: Maintaining correct tyre pressures helps your vehicle run more efficiently which can save fuel consumption. Under-inflated tires increase rolling resistance, making your engine work harder and consume more fuel.

Extend Tyre Life: Correct tyre pressures reduce uneven tyre wear which extends the life of your tyres. The benefit is lower maintenance costs and fewer tyre replacements over the life of the your vehicle.

Environmental Benefits: Correct tyre pressure results in lower fuel consumption that helps reduce your vehicles carbon emissions and footprint. Less tyre wear also means reduced rubber and dust particles being produced by tyres that are wearing unevenly producing more tyre rubber dust than normal.

What does the TPMS warning light mean?

The TPMS sensor and onboard computers have detected incorrect tyre pressures, TPMS tyre sensor faults or abnormal tyre operating conditions.

What do I do when the TPMS warning light is illuminated?

When safe to do so safely PARK then EXIT your vehicle. Check all tyres via manual inspection looking for abnormal signs of tyre wear, underinflation, almost flat or potential tyre punctures. Where possible check for foreign objects or signs of a potential slow puncture. Inflate your tyres to the recommended tyre pressure or visit your local tyre dealer for professional inspection.

How do I turn off or reset the TPMS warning light?

TPMS lights are turned off when correct tyre pressures are detected, onboard TPMS resets are initiated via vehicle dashboards, faulty sensors replaced or abnormal tyre conditions are remedied.

What happens when I replace my tyres?

Your tyre installer can order new sets of TPMS sensors specific to your vehicle and ensure all TPMS systems are reset and working correctly. Use our TPMS sensor search to find the right sensor for your vehicle.

What pressure should I inflate my tyres to?

All Australian compliant vehicles are required to affix a load and tyre pressure label on the driver side door pillar. This sticker outlines the correct tyre pressure recommended by the vehicle manufacturer. Check the owners manual also for further information on recommended tyre pressures.

How do I check my vehicles tyre pressure?

Almost all service stations and convenience stores have AIR & WATER bays with digital pressure gauges that easily allow you to set and obtain the correct tyre pressure. Correct pressures are achieved when the buzzer, beep or audible tone meets your pre-set pressure.

Many aftermarket tyre pressure testing gauges are available from automotive parts stores and major retailers.
