How Much Does a Tyre Pressure Sensor Replacement Cost?

Replacing one tyre pressure sensor typically costs between £60 and £150, including fitting and programming the new sensor to your car. The price depends mainly on whether the garage fits an aftermarket sensor or a manufacturer part, and on your make and model.

Because the sensor sits inside the wheel, the tyre has to come off the rim to reach it. That’s why it usually works out cheapest to replace a sensor while you’re having new tyres fitted.

What Does a Tyre Pressure Sensor Do?

A tyre pressure monitoring system (TPMS) warns you if a tyre starts to lose air through a dashboard warning light.

Every new passenger car sold since November 2014 must have one, and there are two types.

• Direct TPMS uses a small, battery-powered sensor inside each wheel, usually built into the tyre valve. It measures the pressure in that tyre and sends the reading to your car’s onboard computer.

• Indirect TPMS has no sensors in the wheels. Instead, it uses the anti-lock braking (ABS) system to spot a wheel turning faster than the others, which is what happens when a tyre’s pressure is low.

Only direct systems have sensors to replace. Your handbook will tell you which type your car has.

Why Do Tyre Pressure Sensors Stop Working?

Most sensor faults come down to one of five causes:

• A flat sensor battery. The battery is sealed inside the sensor and lasts for many years, but it can’t be replaced on its own, so the whole sensor needs replacing once it runs out.

• Damage during a tyre change. The sensor sits right where the tyre fitter works, so it can be knocked or damaged when a tyre is removed or fitted.

• Corrosion. The valve stem is exposed to rain, grime and road salt, and over time it can corrode or start to leak.

• A wheel without a sensor. Space-saver spares and some replacement wheels don’t have a compatible sensor, so the system can’t pick up a signal from that corner of the car.

• A new sensor that hasn’t been set up. New sensors often need programming, and the car then needs to “relearn” them before it recognises their signal.

“Tyre Sensors Not Detected”: What to Check First

Before you book anything, check your tyre pressures while the tyres are cold, as a sensor fault and genuinely low tyre pressure can happen at the same time. If the message came on straight after a tyre change, new wheels or fitting the spare, mention that to the garage, as it points them towards the likely cause.

Some cars need a reset or relearn after the pressures have been adjusted, so check your handbook for the right steps. If the warning stays on or keeps coming back, a garage can test each sensor with a TPMS tool to find out which one has failed before replacing anything.

Will a Faulty Tyre Pressure Sensor Fail an MOT?

Yes, if your car was registered on or after 1 January 2012. Under the MOT inspection manual, a tyre pressure monitoring system that’s malfunctioning or obviously not working is a major defect, which means an MOT failure.

If your car doesn’t have TPMS, there’s nothing for the tester to check so your car can’t fail on this item.

Not every warning light leads to a failure either. If the light is on because a tyre has lost pressure, the system is doing its job, and a dashboard message isn’t a defect in its own right. Where the tester can’t tell whether the light means a system fault or low tyre pressure, they can add an advisory instead.

Either way, it’s worth getting a warning looked at before your MOT is due.

Do I Need to Replace All Four Tyre Pressure Sensors?

Not necessarily. A garage can test each sensor individually to see which ones have stopped responding, so you only need to pay for the sensors that have actually failed.

However, if you’ve replaced multiple sensors together in the past, chances are they will all run flat around the same time. If one has gone on an older car, your garage may suggest replacing the others too, especially if you’re having new tyres fitted and the wheels are already off.

Warning Signs Your Tyre Pressure Sensor Needs Replacing

You might need a new tyre pressure sensor if you notice any of the following:

• The tyre pressure warning light flashes for a while when you start the car, then stays on

• A “tyre sensors not detected”, “TPMS fault” or “check system” message on the dashboard

• The warning stays on even though all four tyres are at the right pressure

• Warnings that come and go, or appear when nothing is wrong with the tyres

• One tyre missing from the pressure readout on your dashboard screen

• The warning appeared straight after a tyre change, new wheels or fitting the spare
