How accurate are TPMS sensors?

TPMS sensors, which are responsible for monitoring tyre pressure, are known for their impressive accuracy.

These sensors use advanced technology to detect even the slightest changes in tyre pressure and can alert the driver when the pressure falls below a certain threshold.

There are two types of TPMS sensors: direct and indirect.

Direct TPMS sensors use pressure sensors that are installed inside the tyre to measure the pressure in real-time. These sensors can accurately measure the pressure of each individual tyre and can provide precise readings. Direct TPMS sensors are generally more accurate than indirect TPMS sensors and can provide real-time data to the driver.

Indirect TPMS sensors use the anti-lock braking system (ABS) to measure tyre pressure by detecting changes in the rotational speed of a vehicle’s wheels.

While indirect TPMS sensors are considered less accurate than direct TPMS sensors in detailing the exact level of air pressure, they are very effective at detecting changes in a tyre’s pressure.

The level of accuracy for a TPMS depends on several factors, such as the type of sensor used and the quality of the equipment.

External factors also have a say – such as changes in the temperature, road conditions and tyre wear.

In addition to their accuracy, TPMS sensors are also highly reliable. They are designed to function consistently and accurately over long periods of time, which means that drivers can rely on them to provide accurate and timely alerts about changes to a tyre's air.
