How Long Do TPMS Sensors Last?

If you have a TPMS warning light that has recently come on but your tyre pressures are correct, you might be wondering: How long do TPMS sensors last?

TPMS (Tyre Pressure Monitoring System) sensors are designed to monitor tyre pressures in real time to ensure vehicle safety. However, like any electronic component, they are subject to wear and eventual failure.

At Uni Tyres Mobile Tyres Services, we have extensive experience replacing TPMS sensor valves across Hayes and surrounding areas. As a mobile tyre fitting service (with no physical garage), we provide convenient TPMS sensor replacement at your location.

Whether you are driving through Uxbridge, Ealing, or heading towards Slough, understanding TPMS sensor lifespan helps you stay prepared for potential issues.

What Is a TPMS Sensor?

TPMS stands for Tyre Pressure Monitoring System. It is a small electronic device installed inside each tyre, typically attached to the valve stem.

The sensor monitors tyre pressure and sends data wirelessly to your vehicle’s onboard computer. If pressure drops below the recommended level, a warning light appears on the dashboard.

TPMS has been mandatory in all newly manufactured vehicles sold in the UK since 2014.

How Long Do TPMS Sensors Typically Last?

Most TPMS sensors last between 5 to 7 years.

The main reason for failure is the internal sealed battery, which cannot be replaced. Once the battery is depleted, the entire sensor unit must be replaced.

Drivers in busy areas such as Harrow and Wembley who commute daily may experience earlier sensor failure due to higher usage.

Why Do TPMS Sensors Fail?

1. Battery Depletion

This is the most common cause of TPMS sensor failure. The sealed battery lasts several years, but once it runs out, replacement is required.

2. Corrosion

The valve stem is constantly exposed to:

• Road salt
• Water
• Dirt
• Harsh weather conditions

Over time, corrosion can damage the sensor. Drivers in Ruislip and Northolt may experience this issue more frequently.

3. Physical Damage During Tyre Changes

TPMS sensors can sometimes be damaged during tyre replacement if not handled properly.

4. Road Impact

Hitting potholes or kerbs can damage the internal components of the sensor. Drivers in Richmond and Twickenham may encounter such road conditions.

Signs Your TPMS Sensor May Be Failing

Common warning signs include:

• Flashing TPMS warning light
• Dashboard message indicating TPMS fault
• Inaccurate pressure readings
• Warning light repeatedly appearing
• TPMS warning despite correct tyre pressure

If the TPMS light flashes for around 60 seconds and then stays on, it often indicates a faulty sensor.

Can You Drive With a Faulty TPMS Sensor?

Yes, you can technically drive with a faulty TPMS sensor, but it is not recommended.

You may be:

• Unaware of a slow puncture
• Driving with underinflated tyres
• Experiencing longer braking distances
• Using more fuel than necessary
• At risk of MOT failure if the warning light remains active

TPMS is an important safety feature and should be kept in proper working condition.

When Should You Replace TPMS Sensors?

You should consider replacing your TPMS sensors:

• If they are over 5–7 years old
• When replacing all four tyres
• If battery failure is confirmed
• If corrosion is causing air leakage
• If the warning light flashes repeatedly

Replacing sensors at the right time can reduce long-term labour costs.

TPMS Reset After Replacement

After replacing a TPMS sensor, the system must be properly reset. This may involve:

• Reprogramming
• System synchronisation
• Calibration using diagnostic equipment

Professional diagnostic tools are typically required to complete this process correctly.
