Do TPMS sensors need replacing?
Yes, TPMS sensors do need replacing over time. Most TPMS sensors contain sealed batteries that eventually fail, meaning the sensor can no longer communicate with your vehicle.
If your TPMS warning light is on and you are based in London or Essex, the issue may not just be tyre pressure — it could be a failing sensor that needs diagnosing or replacing.
If your warning light stays on, you may need TPMS diagnostics or sensor replacement to identify the issue correctly.
How long do TPMS sensors last?
Most TPMS sensors last between 5 to 10 years, depending on usage, driving conditions and vehicle type.
- Vehicle age
- Driving conditions
- Exposure to corrosion
- Sensor battery life
As vehicles get older, TPMS sensor failure becomes more common due to battery depletion.
Signs your TPMS sensor may be failing
A failing TPMS sensor can cause several issues. Common signs include:
- TPMS warning light stays on
- Warning light flashes and then stays on
- No tyre pressure readings
- Intermittent TPMS faults
If you’re unsure what the warning light means, read our guide on what TPMS is and how it works.
What causes TPMS sensors to fail?
TPMS sensors can fail for several reasons, including:
- Battery depletion (most common cause)
- Physical damage during tyre changes
- Corrosion of the valve stem
- Sensor communication faults
In most cases, once the battery inside the sensor fails, the entire sensor must be replaced.
Do TPMS sensors need programming after replacement?
Yes. Many vehicles require TPMS sensors to be programmed or relearned after replacement. This ensures the vehicle recognises the new sensor correctly.
Some vehicles auto-learn sensors, while others require specialist diagnostic equipment to program sensor IDs.
To understand how different systems work, see our guide on direct vs indirect TPMS systems.
When should you replace TPMS sensors?
You should consider replacing TPMS sensors if:
- The sensor battery has failed
- The TPMS warning light remains on
- Sensors are damaged or corroded
- You are replacing tyres on an older vehicle
In many cases, replacing sensors proactively during tyre replacement can save time and labour costs later.

Frequently asked questions
How do I know if my TPMS sensor is bad?
Common signs include a constant TPMS warning light, no pressure readings or intermittent faults. A proper diagnostic check confirms the issue.
Can TPMS sensors be repaired?
In most cases, TPMS sensors cannot be repaired because the battery is sealed. The sensor usually needs replacing.
How much does TPMS sensor replacement cost?
Costs vary depending on the vehicle and sensor type. Diagnostics are recommended first to confirm whether replacement is needed.
Do all cars have TPMS sensors?
Most modern vehicles use TPMS. Some use direct sensors, while others use indirect systems without physical sensors.
