Get To Know Your Tire Pressure Monitoring System Safety Device

The National Highway Traffic Safety Administration (NHTSA) requires all vehicles made after 2007 to come equipped with a Tire Pressure Monitoring System (TPMS) warning system. The TPMS light on your dash is a safety device that wirelessly monitors tire pressure through a sensor in your tires and the valve attached to it. If your TPMS light comes on, it’s telling you something— don’t ignore it!

Get Your Recommended Tire Pressure

IF YOUR TIRES ARE NOT PROPERLY INFLATED, YOU COULD BE RISKING:

  • Your safety. Underinflated tires can cause catastrophic tire failure, leading to accidents.
  • Your tire performance. Underinflated tires can lose traction and responsiveness in all weather conditions.
  • Lower fuel economy.1 Underinflated tires make your vehicle work harder and use more fuel.
  • Increased tire wear. Underinflated tires can wear out your tires faster.

IF YOUR TPMS LIGHT IS BLINKING OR SOLID, HERE’S WHAT IT MEANS:

If your TPMS light blinks 3-5 times and then turns solid, your system is malfunctioning and requires some type of service. One or more of your TPMS sensors are not communicating with the system.

If your TPMS light illuminates and remains sold, you have a pressure issue inside your tires based on the manufacturer’s recommended tire pressure. You can find the recommended tire pressure on the tire placard sticker, located on the driver’s side door jamb or on the gas tank door.

When should you service your TPMS sensors and valves?

TPMS sensors are battery powered and last 7-10 years and/or 100,000 miles. The battery inside the sensor isn’t replaceable, so when you have one sensor replaced due to battery failure, it’s recommended you replace all four sensors.

A proper TPMS service requires a special tool and a reset of the sensor system in your vehicle, so make sure a professional mechanic, like your trusted technician at Firestone Complete Auto Care, performs this service. You can rest easy knowing Firestone Complete Auto Care only carries the highest standard TPMS sensors that work with nearly all of the vehicles on the road, so we have you covered.

Maintaining the TPMS tire valve is also very important in preventing air loss that could cause the solid light to come on. Your TPMS sensor comes equipped with a metal or rubber valve stem, and each valve has specific components that need to be replaced each time you have new tires installed or during a tire repair. Ask a teammate for more details.

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.

The process of replacing the battery in the tire pressure sensor

There are few motorists who would pay due attention to tire pressure. Usually the amount of atmospheres is checked before a long trip or after replacing one set with another (for example, in the off-season).

Meanwhile, the pressure in the chambers is an important parameter responsible not only for comfort, but also for the safety of the driver and passengers. Manufacturers, knowing about the negligent attitude of motorists to this issue, decided to help them and launched the production of special devices - tire pressure monitoring systems (TPMS).

The device is a controller mounted on wheels and a display that shows up-to-date information. But, like any other device, TPMS eventually fails. Moreover, the most common cause of failure is a battery that has completely exhausted its resource. Therefore, many motorists are wondering: is it possible to replace the battery, because the monolithic design of the sensors does not provide for such manipulations?

Is it possible to replace the battery in the pressure sensor

Most TPMS manufacturers claim that the sensors are non-separable and disposable. In fact, they are lying. Having hands growing from the right place, a set of necessary tools, as well as minimal knowledge of their use, you can easily replace a dead power source yourself.

@drive2.ru

The process of replacing the battery in the tire pressure sensor

Devices that monitor the amount of atmosphere in car chambers, alas, do not last forever. The reason is the batteries that ensure the functioning of the sensors. Moreover, each indicator has its own battery.

Having completely exhausted its resource, the power supply ceases to perform the functions assigned to it. This forces the driver to replace the device. However, if you believe the statements of device manufacturers, the TPMS indicator is a non-separable design, and in the event of a battery failure, the motorist will have to purchase new controllers. But the cost of the system is quite high, because not every vehicle owner can afford to constantly buy a new TPMS.

Craftsmen who have found a way to remove a failed battery come to the rescue. To do this, you will have to prepare several tools and tools that can be found in any household:

  • soldering iron, acid;
  • narrow tip knife;
  • sealing agent: sealant, epoxy resin and other substances with a similar effect.

The process of extracting the old element is as follows:

  1. The first step is to find a suitable place. It should be comfortable and well lit.
  2. Using the tip of a knife, carefully open the indicator and remove the composition that is poured into the inside of the device.
  3. The standard power supply is attached to the contacts by soldering. They must be carefully disconnected, and the battery that has become unusable must be removed. When performing manipulations, it is important to remember where the positive and negative contacts are located.
  4. Use a soldering iron and acid to solder a new battery to the contacts. Work should be done carefully, trying not to overheat the battery. Otherwise, the battery may leak or explode.
  5. When the new power supply has taken its place, you need to assemble the device case and restore the tightness with epoxy or another compound that has a similar effect.

Help. The refurbished sensor should be left for about a day to allow the epoxy to dry completely. After this period, the device is installed back on the wheel.

@carax.ru

How quickly the battery in the pressure sensor runs out

Usually, manufacturers install Swiss or Israeli-made batteries. The average life of these batteries is about five years. However, it largely depends on the operating conditions. If the indicators are left without pressure during the off-season, and during this time they will regularly give an alarm signal, the battery will fail faster.

They will also “sit down” faster if moisture gets inside the device or when used in conditions of prolonged frost (from -35 ° C and below).

The new TPMS sensors don't come cheap. And it's a shame when they fail. Although it is always possible to purchase a new device, it is still better to first try to replace the old battery with a new one, because it is a dead battery that is the most common cause of device failure. As a result, the motorist receives a fully functioning product and saves the family budget.
