TPMS sensor replacement and programming at your door

What a TPMS sensor does

A direct tyre pressure monitoring system has a small sensor inside each wheel, usually built into the valve stem. It measures pressure and temperature and sends the reading by radio to the car. When one tyre drops well below its target, a warning light appears on the dashboard, and many cars show the pressure of each tyre on the screen.

Each sensor runs on a sealed battery. When the battery dies, the whole sensor has to be replaced. Some cars, particularly older Volkswagen and Honda models, use an indirect system that reads wheel speed through the ABS instead; those have no sensor to replace and just need the system reset after the pressures are corrected.

Low tyre or faulty sensor: telling the difference

A pressure warning does not always mean the sensor is at fault. Before replacing anything, we always measure the actual pressures with a calibrated gauge. If you want the basics on what the light means, our tyre pressure guide covers it; this page is about the hardware.

Why sensors fail in the UAE

• Battery age. Sensor batteries are sealed and are not replaceable on their own. As they age, sensors on cars from the late 2010s are reaching the end of their life.
• Heat. The inside of a wheel in a Dubai summer gets far hotter than the outside air, especially after braking, and electronics age faster at high temperatures.
• Corrosion. Aluminium valve stems can seize or crack, especially if the valve cap has been missing for months.
• Fitting damage. A careless tyre change can snap a sensor if the machine operator does not know where it sits.

How replacement and programming work

1. The technician reads every sensor with a TPMS tool to find which one has failed and confirm the car's sensor type and frequency.
2. The wheel comes off, the tyre bead is broken on the changer in the van, and the old sensor is removed.
3. A new sensor is programmed with the correct protocol for your car, and fitted with a new seal and valve core.
4. The tyre is refitted, inflated to the door-placard pressure and balanced.
5. The new sensor is relearned to the car using the tool or the car's own relearn procedure, and the warning light is cleared.

The whole job typically takes 30 to 45 minutes for one sensor, and a little longer per extra sensor.

Aftermarket or original sensors

Our starting price of AED 150 is for a quality programmable aftermarket sensor, which is cloned or programmed to match your car and works like the original. Original manufacturer sensors cost more and are available on request for most models; we quote the difference before ordering. For brand-new cars still under warranty, ask your dealer whether they require original parts.

When to replace sensors together

If one sensor has died from battery age, the others were fitted at the same time and will follow. When you are already replacing tyres, it can make sense to replace all four sensors in the same visit, since the tyres are coming off anyway and you avoid a second call-out later. We fit new tyres from AED 150 each; see our tyre replacement service for how that visit works.

Price per sensor

Each sensor starts at AED 150 including the sensor, programming, new valve seal and relearn. The tyre removal, refit and balancing needed to reach the sensor are part of the job. If sensors are replaced during a tyre fitting visit, the sensor work is simply added to the same visit.
