What is a TPMS Sensor Battery?

Sensors for tyre pressure monitoring systems (TPMS) are built to withstand harsh conditions but still perform well.

The lifespan of a typical TPMS sensor is around 5 to 10 years.

It is a general estimate of how long a TPMS sensor lasts, but it also depends on other features like the type of SensorSensor, how you use your vehicle and the battery condition.

Symptoms of Malfunctioning of TPMS Battery

How do you replace the TPMS sensor? The TPMS battery is not functioning.

Well, I know what I'm thinking about! How do I know if my TPMS sensor is working or not?

Your TPMS battery is malfunctioning, but the question is how to see that it is not working; here is how to find out.

Let's see!

Blinking of TPMS Light

The most common symptom is the blinking of the TPMS light whenever the TPMS sensor goes rough and damaged.

• This light may blink for a minute or half or might be longer.

ECU Missing Transmission Sensor

When the ECU Transmission Sensor starts missing some of the transmission, it might be changed that there is some malfunctioning or interference in your TPMS.

• In that case, the TPMS light will turn on to attract the driver's attention, prompting the driver to check why it is on and what the problem is inside.

Other Symptoms

You also need to check other related things like;

• Checking of Engine Surging During Operation.
• Checking of Low battery voltage.

These are the most common symptoms of malfunctioning TPMS sensors, so keep checking them.

If you find the issue, you may learn how to replace the TPMS battery sensor by following this instruction.

Once you understand this problem and its root cause, you will naturally think of changing and fixing the TPMS sensor. So don't worry; follow this DIY guide to solve this yourself.

Steps to Replace Tire Pressure Sensor Battery

If the TPMS light in your car is blinking unconditionally, you must have a terrible TPMS sensor.

Generally, the SensorSensoris alright because it is the battery inside it that goes strong. 

It is a slightly skilful task, so make sure you have proper preparation, time, and patience to start the process so that you can end it.

Step 1: Gather Tools

Before starting the process, you must have these few things you need.

1. A Solder Tabs
2. Plast Bond (two-component adhesive) OR a silicon
3. A CR 2450 batteries

Step 2: Taking Out the Sensor

You might already have removed the SensorSensor from the wheel, but if you still need to, you must do this first.

Here are the steps you can take to accomplish this.

1. First, raise the vehicle and get the tyre out of it.

 I recommend using a pneumatic press for this, but can you apply the method whichever you prefer?

2. Unscrew the TPMS sensor from the back of the valve stem.

Step 3: Disassemble Its Rear Cover

Set the rear side of the Tpms sensor toward you; mostly, you found two noches and two tabs here.

Open the TPMS sensor with the help of a screwdriver.

Remove its whole back cover; when you open up the cover, you might see all silicon-type white subsistence.

Step 4: Remove or Scratch the White Substance:

As I mentioned, you will see a white silicon-type substance after removing the back cover.

• The left half of TPMS contains a battery, while the right half includes a sensor.

It's time to take a screwdriver and continue scratching the silicon.

• Scratch all over it and take out the actual circuit, SensorSensor and the battery. 

Make sure all sides are properly cleaned up from silicon.

While you are doing this, be careful not to break the circuit board on the right side.

Step 5: Remove Battery and Sensor

After cleaning the silicon, you can remove the sensor sensor and electronic parts to work without any irritation or concern.

• You can use any needles or plastic tools to remove any leftover silicon after removing them.

Step 6: Separate the Battery from the Sensor

After that, you will have to unsolder the old battery from the SensorSensor, but how can you do this?

First, make sure the solder points or connection points are cleaned enough.

Take a soldering iron to take these two connections out.

With pressure from upside down on the connections, you can easily unsolder them.

TIP: you can take a solder wick and clean the connection properly after separating it from the battery.

Step 7: Put New Battery On

Get your new battery and begin selling it to the electronic component cautiously. Even a little slip could result in a short circuit.

What if I Got a Wrong Battery?

Whenever you buy a new battery, I warn you that you might not get the battery you want, even if its part number is the same.

The irregularity is the difference in prong size and distance between prongs.

If this happens, don't worry. It is standard as this battery goes in several different things, so it isn't a big deal.

Now, what can you do? You have to modify it and make it according to your needs by cutting and pulling it together.

After modification, bend the battery to check; if it fits, check whether it works using the TPMS Diagnostic Device.

Step 8: Check Connection

Now, you need to check the connection and ensure they are solid.

• You can use a multimeter to double-double-check at connection points.
• Also, you can use the TPMS Diagnostic Service to check if the new battery is working.

Step 9: Put the Battery and Sensor Back

Now it's time to put everything back where it belongs. Take a sensor with a new battery and fix it properly. 

Once you've fixed and set it, you'll need to solder it again. Then, clean it a bit by using any cleaning tool.

Before sealing it, you must ensure this works with a TPMS sensor diagnostic device.

Step 10: Seal Back the TPMS Sensor

After it is all done, you have to cover the area so that three inner things remain protective and safe.

In order to do so, you can use the following methods;

1. A silicon
2. Epoxy two components adhesive

Where have you put these?

1. Apply it at the inner surface, then insert a battery with an electronic section into the housing.
2. After inserting the battery, you must cover all the above areas and surround it with glue or silicon.

Put everything back in its place, close its cover, and you are done replacing the TPMS battery.

Is it necessary to replace your TPMS battery whenever you replace tyres? 

There isn't a straight answer to this query, However, you should consider some factors before making a decision.

1. For example, examine how long the tyres have been on the road.

• By the time they wear out, the TPMS sensors may have reached the end of their useful life.

1. After that, another critical impact is the battery, so you also have to consider it.

• Your TPMS sensor is mostly in an excellent working state, but its battery gets ill, so you feel the need to replace it.

Five to ten years is the average life expectancy of lithium-ion batteries used in TPMS sensors.

Whenever your batteries get old and it is not working, then you can try one of these options;

1. Replace Your TPMS Batteries
2. Get a New TPMS sensor

Replacement of TPMS Sensor in Modern Vehicle

If you have a newer and more modern vehicle, the process may be more straightforward for you. These have an automatic mechanism that allows you to re-adjust the sensors without touching them.

Replacement of TPMS Sensor in Old Vehicle

However, replacing the TPMS sensors is more complex than removing the old one and installing the new one.

Once you've removed the TPMS sensors, the new one must relearn the wheel location for each SensorSensor.

It does occur whether you swap out one, two, or all four sensors.

What is the Process of Adopting a TPMS Sensor?

Sometimes, the procedures entail using a magnet or TPMS-specific service instruments. These will allow you to control the sensors throughout the retraining process.

If you don't use the proper tools, the system will not learn the wheel placements correctly.

What is The OutCome?

When replacing the wheels, it is recommended that the TPMS sensors be completely replaced. You are not required to do so, but it will save you a lot of trouble.

How Often You Can Replace TPMS Battery? 

Firstly, if you have no experience working with vehicle parts, make sure to consult an expert or contact a technician.

The technician will now inspect the pressure monitoring system.

And then let you know the steps to follow to reach a working state.

The lithium-ion batteries used in TPMS sensors have a 5-10 years life.

Most TPMS sensors are powered by built-in batteries, which cannot be replaced. 

What is The Cost of Replacing a TPMS Sensor Battery?

Well, its cost depends not only on the price of the new TPMS sensor but also on the labour cost, type of vehicle, and sensor type.

• You can get a cheap TPMS sensor at AMAZON for just $30.
• A suitable TPMS sensor at AMAZON can be available at $60.

The cost to change the TPMS sensor battery is between $50 and $150. If you require the services of a professional, the price may be slightly higher.

How to Maintain The TPMS Battery?

Before you dive into the maintenance of TPMS batteries, I recommend you learn how TPMS works to understand better how to care for TPMS battery Sensors.

How does the TPMS work, and how do we maintain it?

Maintaining your TPMS battery can be accomplished in a few ways.

• TPMS batteries usually transmit when resting but transmit maximum while in motion.
• While driving on highways, you need to remain focused and maintain a constant speed.
• By doing this, the lifespan of TPMS batteries increases because sensors transmit less.

• Avoid starting and stopping driving as much as possible; it also significantly affects a car's TPMS.

• Also, it is crucial to take into account whether it affected TPMS as well.
• Cold conditions would help preserve it in good condition, while warm conditions mostly take a toll on the battery.

If you focus and check on these few things, then this is enough for it to last longer, and you also don't feel the need to spend on new batteries.
