How to replace tire pressure sensors


Replacing Tire Pressure Sensors Is More Complicated Than You Think

Tire pressure sensor guide highlights:

  • Tire pressure sensors can be either indirect or direct; and if they’re direct, they can be either valve stem or banded types
  • Incompatible wheels, frequency mismatches, and dead batteries can cause sensor problems, as can corrosion, physical damage, and extreme temperatures
  • Once you have the right tire pressure sensors installed, resetting the TPMS light usually only requires a short drive

Many drivers worry about big maintenance tasks, but the ‘little’ things are often the most annoying. And sometimes, as I learned after a disastrous spark plug change, they’re the easiest to screw up. Compared to that, dealing with tire sensor problems seems like a cakewalk. However, if you’re dealing with an illuminated TPMS light, know that it’s not as simple as it looks.

Tire pressure sensors aren’t universal2013 Fiat 500 Abarth valve stem type tire pressure sensors | Matthew Skwarczek, MotorBiscuit

If you want to see how inflated or deflated your car’s tires are, you use a tire pressure gauge. Your car’s tire pressure monitoring system (TPMS) has gauges, too, in the form of tire pressure sensors. And thanks to the TREAD Act, if your car is a 2008-or-later model, it has these sensors. But which kind often changes across models and brands.

TPMS tech falls into two categories: direct and indirect. Indirect systems use ABS sensors to measure wheel rotation. If these sensors find one tire is spinning faster than expected, that means it’s under-inflated, which triggers the familiar warning light. In contrast, direct systems rely on individual sensors attached to each wheel. These directly measure the air pressure in a tire and relay that information wirelessly via radio signals to a central module. And if a sensor sees the tire pressure is under the recommended level by 25% or more, it triggers the warning light.

Because these systems are so different, it stands to reason that you can’t replace direct tire pressure sensors with indirect ones or vice versa. However, you also can’t necessarily swap direct sensors between cars. And that’s because there are two direct sensor types, NAPA explains.

Some direct tire pressure sensors are the ‘valve stem type.’ As in, they’re basically sensors with valve stems attached. Meanwhile, ‘banded type’ sensors are, well, bands mounted to the wheel 180° across from the valve stems. And again, valve stem sensors aren’t interchangeable with banded ones.

Make sure you have compatible wheels

Normally, drivers only deal with tire pressure sensors if they or the whole TPMS has a problem. Usually, that means a blinking warning light and/or an error message. However, they also become an issue if, like me, you have separate wheel-and-tire sets for winter and summer.

Yes, you can always have one set of wheels and repeatedly swap tires as the weather demands. But removing and installing tires is tough without a dedicated machine. And rather than paying someone multiple times to put the tires on, you only need to pay them once. Well, twice: once in the winter and once in the summer/spring. So, having separate wheels for separate seasons saves time and money.

But if your car has TPMS, you also need a second set of tire pressure sensors. Otherwise, the warning light would stay on all winter. Then you wouldn’t know without checking if your tires are low on air.

Yet there’s another complication here. Technically, aftermarket suppliers aren’t obligated to follow that TREAD Act I mentioned earlier. As a result, not all aftermarket wheels are TPMS-compatible. Admittedly, per the TREAD Act, tire shops are legally obligated to not use aftermarket parts if they would disable the TPMS. But that still doesn’t guarantee that your fancy wheels won’t throw warning lights without additional modifications.

RELATED: 5 Myths About Tire Safety That Every Driver Should Be Aware Of

That statement flashed into my head when my Fiat 500 Abarth’s TPMS warning light went on after I switched to my summer wheels. But then I remembered I had compatible wheels. At which point, I started thinking about my tire pressure sensors. I’d bought them new from a Stellantis dealership after triple-checking the compatibility, so I thought they’d be good.

As it turns out, they weren’t. When I went to a Fiat dealership to diagnose the problem, it turned out that Stellantis offered two kinds of sensors for my Abarth. One was a so-called ‘value line’ option, while the other was a twice-as-expensive OEM version with a different part number. And after installing the pricier sensors, the light went away.

So, is the lesson here not to buy cheap tire pressure sensors? Well, yes and no. True, cheap parts cost less for a reason. But in this case, the price wasn’t necessarily the culprit. As it turns out, although TPMS sensors communicate via radio frequencies, they don’t operate on the same frequency. It’s possible my Abarth’s module simply couldn’t pick up what the cheaper sensors were sending out. And since it couldn’t ‘hear’ the sensors, it assumed there was a fault and threw up that light.

Alternatively, it could be that my Abarth’s TPMS is a high-line system and the value sensors were for a low-line one. High-line systems are more expensive but let cars display pressures for individual tires, Edmunds explains. Also, their sensors only transmit information when the car prompts them. Low-line systems, on the other hand, have their sensors transmit at random intervals. They’re cheaper, but they can’t display individual tire pressures. And without careful programming, these sensors can crosstalk.

Regardless, it wasn’t the most expensive goof-up I’ve ever done, but it’s still not fun paying twice for the same part. And even a set of four cheap sensors often costs at least $100, not including installation costs. Learn from my mistakes and save some cash.

Dead batteries aren’t the only things that cause sensor faultsA Lexus dial with an illuminated TPMS light | Patrick Whittemore/MediaNews Group/Boston Herald via Getty Images

RELATED: Will Properly Inflating Your Tires Actually Improve Gas Mileage?

There’s a simpler explanation for my TPMS woes: the tire pressure sensors were dead. Considering I bought them brand new from a Stellantis dealership, I highly doubt that all four would be faulty. But that doesn’t mean sensors can’t go bad over time.

With direct tire pressure sensors, faults are often caused by dead batteries. The batteries typically last a few years, but they’re not replaceable. When one dies, the entire sensor gets replaced.

But other things can cause sensor faults. Extreme cold and heat as well as repeated pothole trauma can damage both kinds of direct sensors. Valve stem types are also susceptible to valve-stem corrosion. Hence why you should always keep the caps on. Furthermore, tire sealants can damage sensors if they’re exposed for an extended period. So, if you use it to temporarily fix a leak, make sure you clean your sensors afterward.

Will replacing the sensors reset your TPMS light?

RELATED: Do All Cars Use the Same Type of Oil Filter?

If your tire pressure warning light comes on, don’t immediately start sensor shopping. First, make sure that your tires are properly inflated. Then, go for a short drive to let the TPMS reset. Only if that doesn’t do the trick should you start eyeing the sensors as culprits.

Whether you’re replacing old sensors or putting new ones on your second set of wheels, you need to reset your car’s TPMS. If a mechanic is doing the work, they have a special tool for the job. But most cars’ systems automatically reset after you drive a few miles above a minimum speed. If yours doesn’t after installing new sensors, you might have bigger problems, like a malfunctioning receiver module.

As I said, tire pressure sensor replacement isn’t as straightforward as it looks. But if you pay attention to what your car needs, it’s not something you have to worry about. And hey, even if it breaks, checking your own tire pressure isn’t that big of a hassle.

TPMS Service, Tire Pressure Monitor System Reset & Replacement

When your Tire Pressure Monitoring System (TPMS) lights up, one or more of your tires might be under-inflated. Or your TPMS system itself might need service -- from a simple reset to new seals to a TPMS sensor replacement.

Your Midas technician can check your tire pressure, tell you why the light is on, and make sure your TPMS is working to alert you to any dangerous loss of tire pressure.

What is the TPMS light?

The TPMS light is a dashboard alert that lets you know when one or more of your tires is under-inflated. Depending on your vehicle, tire pressure is monitored either by your ABS system or by a battery-powered sensor mounted on each wheel or tire. Your Tire Pressure Monitoring System is an important safety feature because under-inflated tires pose an increased blowout risk. TPMS is also a cost-saving feature because low tire pressure shortens tire life. An under-inflated tire wears down prematurely at the edges.

What services are available for the TPMS system?

Different TPMS systems have different repair and service options. For instance, most TPMS sensors do not have removable batteries, so the entire sensor must be replaced when the battery is drained. Here are the TPMS service options at Midas:

  • Tire inspection to rule out slow leaks as a cause of tire under-inflation.
  • Diagnostic check (and servicing) of TPMS system1.
  • Replacement seals and nuts on TPMS sensors (TPMS Service Kit).
  • TPMS sensor battery testing.
  • TPMS sensor replacement, installation and programming.
  • TPMS reset after tire service.

Why is my TPMS light on?

A steady TPMS light usually means one or more of your tires is under-inflated. Depending on your vehicle, various pressure conditions may trigger a TPMS alert, such as a sudden change in pressure, or your tire pressure falling too low by a certain percentage. A blinking or flashing TPMS light usually indicates an issue with the TPMS system itself, such as a dead TPMS sensor battery. Check your vehicle manual to learn what triggers your particular TPMS light.

Why is the TPMS light still on?

If you’ve added air to your tires and verified their inflation levels with a tire pressure gauge, there are three possible reasons for the TPMS light to stay on:

  1. Your TPMS needs resetting: Some sensors require a TPMS reset after adding air as well as rotating or replacing tires. Check your vehicle manual for the procedure.
  2. Your TPMS needs service: Likely if the light is blinking and your verified tire pressure is stable.
  3. A slow tire leak: Likely if the TPMS light is steady after adding air. Keep monitoring tire inflation. If your verified tire pressure drops too quickly, it’s time for tire repair.

Is it safe to drive with the TPMS light on?

It is only safe to drive with the TPMS light on if you’re certain your tires are maintaining proper pressure (suggesting the light is on because of a TPMS system issue). It’s unsafe to drive on improperly inflated tires, so check your tires with a pressure gauge as soon as your TPMS light comes on. If your tires maintain correct pressure but the light still won’t go off, it’s time for diagnostic service on your TPMS. In this case it’s OK to drive in the short term, as long as you monitor your tire pressure carefully -- and remember that you may not be reliably alerted to dangerous changes in tire pressure.

Does TPMS need to be replaced?

A TPMS sensor is typically replaced when its battery runs out. Very few sensors come with removable batteries, so the lifespan of a TPMS sensor is usually equal to its battery life.

Do I need to replace TPMS when replacing tires?

You don’t need to replace your TPMS sensors when buying new tires, but it’s often convenient to do so if the sensors are more than a few years old. Most TPMS sensor batteries last five to ten years, so older sensors may not last as long as your new tires. Many drivers prefer to avoid the hassle of replacing TPMS sensors mid-way through the tire lifecycle.

Midas recommends a TPMS Service Kit when replacing tires. This kit contains replacement parts for the sensor’s valve stem seals and nuts to ensure a perfect fit to your new tires.

Your local Midas technician can help you decide whether to replace TPMS sensors based on the life expectancy of your new tires, and we’ll be here to replace your sensors when the time is right.

Should I have the TPMS reset after replacing tires?

You should always reset your TPMS after changing or rotating tires, or installing new sensors. Some sensor manufacturers recommend resetting it even after adding air to your tires. Resetting the TPMS is often described as retraining the main TPMS system by teaching the system to recognize the sensors in their new positions. Depending on your vehicle, the TPMS reset procedure consists of sequence of ignition and pedal movements, or changing a setting in your dashboard menu, or using a TPMS Reset Tool.

Check your vehicle manual or ask your local Midas technician how to reset your TPMS after tire service.

How to tire change wheels with pressure sensors - Tuningberg

TPMS equipment is a useful option that is equipped with modern cars. TPMS monitors the tire pressure and signals the change in the parameter to the on-board computer.

If such equipment is installed on your car, this is not an obstacle to fast and high-quality tire fitting. But it is difficult to cope with this task on your own, since the use of specialized equipment is required. To the question of how to tire with pressure sensors, the answer is simple - visit Tuningberg LLC, where experienced craftsmen will perform the work in the shortest possible time. Our mechanics visually determine the presence of control equipment, but it is safer to warn about the gadget in advance, since the sensors are very fragile and prone to breakage.

Pressure sensors

Control and measuring devices are made of two types: external and internal.

  • The outer ones are mounted on the tire inlets, this procedure can be done by yourself, but you will have to visit the tire shop, because the equipment is heavy and the suspension will be unbalanced. External devices can become easy prey for car thieves or be damaged by a foreign object.
  • Internal is a high-tech equipment mounted in a disk. It transmits the signal to the on-board computer via wireless communication.

When replacing wheels, increased accuracy is required, which will be provided by our masters.

Wheel beading features with pressure sensor

The installed pressure sensor is not a serious obstacle, but requires precautions when mounting or dismantling the rubber.

  • The machine foot starts on the opposite side of the sensor location.
  • When spinning the wheel, make sure that the tire does not press on the device.
  • Separation of the inner bead is done in the same way.
  • When tilting the outer bead, the mounting device is positioned at a distance of 15 - 20 cm after the sensor in the direction of travel.
  • Smooth pressing the wheel is released from the tire. The transfer is being carried out with precautions.
  • Installation is carried out in the reverse order after high-quality soaping of the rubber.
  • Installation starts from 15 to 20 cm after the sensor.

During the process, it is unacceptable to apply external influence to the device. From the description it is clear that it is impossible to carry out work without having the skills and without the use of specialized equipment.

Nuances of operation of internal sensors

If your car is equipped with such equipment, be sure to contact a car service to reinstall seasonal tires. The question arises whether it is possible to install devices on both sets of wheels and replace them yourself. No, it causes difficulties.

  • Only original parts are required for vehicles, and their price is high, the on-board computer does not “see” the rest.
  • The system can "remember" only one set, the data of which is entered into the computer. The signal comes from a specific wheel, it is impossible to rearrange them yourself without damaging the connection with the computer.

After installing the wheels, the computer does not perceive the signal, and this is normal, since the cars standing nearby will transmit information that does not correspond to reality, therefore, recoding of the control equipment is required. This operation is carried out quickly:

  • the mechanic brings a signal recording device to the sensor;
  • the encoder is connected to the on-board computer, the information is recorded.

After that, the circuit returns to normal and functions properly.
