TPMS

Everything You Need to Know About TPMS Sensors for Your Vehicle

What Are TPMS Sensors?

TPMS stands for Tyre Pressure Monitoring System, a crucial safety feature in modern vehicles designed to alert drivers when their tyre pressure is too low. By monitoring tyre pressure, TPMS sensors help improve fuel efficiency, enhance safety, and prolong tyre life. Low tyre pressure can lead to poor handling, increased braking distance and potentially worse!

How Do TPMS Sensors Work?

TPMS sensors, especially in direct systems, are small electronic devices fitted inside the tyre or attached to the valve stem. These sensors measure the internal pressure and sometimes the temperature of the tyre. The data is then wirelessly transmitted to your car's computer, triggering a warning if the pressure falls below recommended levels.

Why Are TPMS Sensors Important?

Maintaining the correct tyre pressure is not just about avoiding a warning light on your dashboard. Here are some key benefits of TPMS sensors:

Improved Safety: Prevents accidents caused by underinflated or overinflated tyres.
Increased Fuel Efficiency: Correctly inflated tyres reduce rolling resistance, improving MPG.
Prolonged Tyre Life: Reduces uneven tyre wear, saving you money on replacements.
Environmental Benefits: Lower fuel consumption reduces carbon emissions.

Common TPMS Sensor Issues

Like any electronic component, TPMS sensors can experience problems over time. Here are some common issues and how to address them:

Battery Failure: Many direct TPMS sensors have batteries that last 5-10 years. If the battery dies, the sensor will need replacing.
Sensor Damage: Rough roads, improper tyre installations or accidents can damage the sensors.
Corrosion: Valve stems, especially metal ones, can corrode and cause sensor failure.
False Alerts: Rapid temperature changes or calibration issues can trigger false warnings.

Replacing TPMS Sensors

If your TPMS sensor fails, it’s essential to replace it promptly. Professional installation is recommended, as it typically involves removing the tyre, pairing the new sensor with the car’s computer, and recalibrating the system. At Chesterfield Tyre & Exhaust we can replace most sensors on the day using the latest technology.
