The Tire Pressure Monitoring System, which notifies you when a tire is dangerously low on air, typically uses TPMS sensors embedded in the tires to detect low tire pressure. The majority of TPMS sensors use internal batteries that cannot be changed to power them.
The lithium ion batteries in a TPMS sensor have a lifespan of 5 to 10 years. It’s hard to establish an exact timetable for how long TPMS sensor batteries will survive as it relies on the amount of radio frequency transmissions the sensors make. The amount of driving you perform over time and the conditions you drive in will affect the sensor battery life. The TPMS battery life is less affected by cold conditions than by warmer ones. When compared to continuous pace, stop-and-go traffic has a greater effect on TPMS battery life. This is due to the fact that sensors send out more radio frequency broadcasts as a vehicle changes its speed.
The system will issue a malfunction warning when a TPMS sensor’s battery runs out, which will be visible as a blinking TPMS light on your dashboard. After 60 to 90 seconds, the light may either continue to flash or turn solid. Be a repair appointment as soon as you can if you receive this warning, but also check the tire pressure in each tire right away to make sure you have safe inflation all around.
You can change each individual TPMS sensor separately if one of them malfunctions and needs to be replaced. The other sensors, on the other hand, are probably on the verge of failing as well if the failure was brought on by a dead sensor battery. You might wish to proactively replace all the sensors so you have brand-new sensor batteries all around when you take into account the time and hassle of taking your car off for a sensor replacement.

Hadley, Mac
The quantity of RF transmissions, which are influenced by the driving environment and sensor design, is directly related to battery life. “Is there a sleep mode for the sensor? In typical circumstances, is it intended to send every minute, every five minutes, or every twenty minutes? An OE battery typically has a lifespan of five to twelve years, with seven years being the average.”
Hi all – I quickly looked through the search but couldn’t find much.
So, how long does a TPMS sensor last? Should they be changed together with the tyres? Do you suppose they have a battery inside to make them function?
“The lifespan of the lithium ion batteries in TPMS sensors can range from five to ten years. For older TPMS sensors, a lifespan of five to six years is more normal. TPMS sensors only transmit while the vehicle is moving; they do not broadcast continuously. To save battery life, the transmission is still sporadic even then.”
Ah, I should have searched Google instead of this site. Thank you for your response; that’s nice to know.
The rear tires need to be replaced. Should I just go ahead and pro-actively replace the TPMS sensors given that my construction date is 9/2009? I don’t know how long they endure, but 9 years seems like a lot of time.
Additionally, is there a generic alternative to the OEM 36236798726 sensors that performs equally well?
Although I installed new tires, swapped out a few curbside wheels, and relocated my 9-year-old sensors to the new wheels a few months ago, I’m still wondering about this. Therefore, I will likely wait until one breaks before replacing all 4 (and paying the mount/dismount fees).
This is something that I recently wondered about. I recently bought some new tires for my 2011 car. The tire shop didn’t inquire if I wanted to get them replaced because I had forgotten about it at the time.
The date of my build is 7/2008. Around a month ago, exactly 10 years after their installation, my TPMS started to malfunction. Said that 1 needed air, and that all needed air ten seconds later. I reasoned that it was time for TPMS modules because I knew that was not doable. I checked the air and added a bit to most of the tires, but it did not help. Maybe a day later, it indicated that only one tire required air. I made a small addition, and since then, everything has worked. For a while, I won’t need tires, but I suppose I’ll install new TPMS modules then.
I recently picked up the August issue of Roundel Magazine, and on page 104 of the Tech Talk section is a message about TPMS Sleuthing.
A 2011 128i with 52,000 miles reportedly displayed a “system inactive” notice with a tire & exclamation point in the centre. According to this, the TPM system batteries typically last 8 to 10 years. Additionally, most tire shops and BMW dealers have a reader to check the monitor sensor’s functionality.
How long is the life of a TPMS sensor?
Batteries that power TPMS sensors have a lifespan of five to ten years. How much you drive over time and the conditions you drive in will affect the sensor battery life.
The cost of a BMW TPMS sensor
Between $245 and $309 is the projected cost of labor, while $352 is the estimated cost of parts. Taxes and fees are not included in this range, nor are your particular model year or special location taken into account.
How frequently must TPMS sensors be changed?
5–10 years is a likely lifespan for TPMS sensors, which are built to last for many years. Given their price, most drivers will opt to repair TPMS sensors “as needed,” that is, only when their batteries run out or other TPMS components malfunction. (The onboard computer in your car ought to react and issue a warning of a TPMS issue or failure.)
Typical TPMS issues that necessitate sensor replacement include:
- TPMS sensor battery failure
- broken TPMS sensors
- Gaskets and/or seals for the TPMS sensor are worn out.
- The TPMS sensor doesn’t send a signal (many possible causes)
- The TPMS valve cores or caps seize up.
What occurs if TPMS sensors are not replaced?
Customers who ask you to turn off their TPMS light just and leave the underlying problem unattended can put you and your business at unnecessary risk. Without addressing the problem, you are breaking the NHTSA’s “make inoperative” clause, which makes shops legally obligated to disable the TPMS. It is your duty to let the customer know this and to decline service if they don’t want the problem handled properly.
It is strongly advised to replace all sensors at once if a single sensor has reached the end of its useful life. When one sensor fails, the others are likely to follow suit quickly, just like with headlights. The same holds true for replacing an impact sensor or damaged valve stem. Your consumers should be aware of this since it will assist you give their vehicle the finest care possible. They also find it convenient.
The TPMS sensors must always be reactivated and calibrated for drivers who change their tires as the seasons change. If you don’t do this, the car’s TPMS won’t function properly and could turn on the TPMS light.
Do TPMS sensors need to be replaced?
A: The batteries in tire pressure monitoring sensors are made to last 10 years. Yours appears to have passed away. Although it is not required by law, it makes sense to replace the sensors for your own peace of mind, convenience, and safety.
How do you tell if the TPMS sensor is malfunctioning?
A few seconds after starting a car, a TPMS icon will appear; however, if it stays on, it means that at least one tire on the car is at least 25% under the recommended pressure. The TPMS system is malfunctioning if the light flashes continuously for one to two minutes.
AutoZone is able to check TPMS sensors.
You can determine if your tire pressure monitoring system is corroding or failing within your wheel with routine inspection; if so, you will need to replace it. For your repair, AutoZone carries every tire pressure monitoring system item you’ll need, enabling you to drive again efficiently and safely.
Can I set up my own TPMS sensors?
Tire pressure sensors with caps are simple to install. You won’t have any trouble working on your car even if you have no prior knowledge. The sensors are often simply screwed into place in place of the valve stem caps.
Do TPMS sensors require programmability?
Without the necessary information, components, and equipment, maintaining TPMS-equipped automobiles financially can be difficult. There are still many misconceptions concerning TPMS despite all the training programs and technical papers on the topic, and the most common one is the mix-up between vehicle retraining and sensor programming.
The problem is caused by the accessibility of aftermarket TPMS sensor modules that are “programmable,” “universal,” or “cloneable.” Before being inserted in the tire, these sensors need to be programmed with the appropriate protocol/application information for the vehicle, and they then need to be retrained to the vehicle. Unfortunately, several shops skip the crucial relearn stage because they think the sensor programming took care of everything. This misunderstanding may result in complaints from customers and service retries.
What is the cost of repairing a TPMS sensor?
Depending on the type of car, the cost to replace the TPMS sensors might be anywhere from $50 and $100 per.
Because servicing TPMS needs additional parts, tools, and labor, TPMS-equipped tires are slightly more expensive to maintain than non-equipped tires. Every time a tire is removed from the vehicle for maintenance or replacement, the TPMS valve service kit, which consists of the valve core, (sealing) cap, nut, and grommet (stem seal), needs to be replaced. On most automobiles, the service kit is between $5 and $10 per wheel. The TPMS system needs to be checked and reset, which takes additional time and a special TPMS programming tool.
A service pack should be used to replace the sealing components of the sensor, which comprise the cap, valve core, grommet, nut, and any other accessory included in the service pack, according to Schrader(r), a producer of original equipment TPMS sensors. The integrity of the TPMS sensor and valve is guaranteed by replacing the service pack components.
TPMS are in my automobile. I haven’t had my repair shop service it yet. What should I anticipate when I arrive?
- Checking the system’s sensors and TPMS for appropriate operation
- Any component of your TPMS sensors that is malfunctioning should be repaired or replaced.
- Your vehicle’s computer will need to “relearn” how to place the TPMS sensors by doing this.
- After the tire service is finished, make sure your TPMS system is functioning properly.
What happens if I have an additional set of wheels and tires (for snow tires or unique wheels)?
You can get a spare pair of tires or wheel assemblies fitted with a set of replacement sensors. Your TPMS installer will be able to relearn the new sensors to the vehicle computer after the extra set of tires or wheel assemblies are attached to the vehicle. The sensors will need to be relearned to the vehicle computer when the original set of tires or wheel assemblies are reinstalled on the vehicle.
What is the price of replacing four TPMS sensors?
Replacement of a TPMS sensor typically costs between $208 and $250. Between $55 and $69 is the expected range for labor costs, while $153 to $181 is the range for part costs. Taxes and other costs are not included in this range, nor are your particular vehicle or geographic area taken into account. Additional fixes could be required.
Do I need to replace the TPMS when I change my BMW’s tires?
Although you don’t have to replace your TPMS sensors when you get new tires, doing so if the sensors are more than a few years old is frequently convenient. Older sensors might not live as long as your new tires because the majority of TPMS sensor batteries only last five to 10 years. The trouble of upgrading TPMS sensors in the middle of the tire lifecycle is something that many drivers would rather avoid.
