All American-made automobiles must have direct or indirect TPMS systems fitted as of 2008 as a result of the TREAD Act’s 2007 mandate.
The TPMS sensors for the Toyota Sienna’s direct TPMS system are mounted inside the wheel. The TPMS sensors will send information to the vehicle’s ECU if one or more tires show low tire pressure. Each tire pressure or an indicator light (low-line TPMS system) will be displayed on the dashboard (high-line TPMS system).
According to the TIA relearn chart, a TPMS relearn is advised to transmit the new TPMS sensor IDs to the vehicle’s ECU whenever a sensor for one or more wheels is changed, the air pressure is adjusted, and the tires have been rotated.

What TPMS manufacturer does Toyota use?
Pacific Industrial Corp. and TRW Automotive are the companies that make the Toyota TPMS. 4 Runner – TPMS Sensors are among the Toyota models that use TPMS technology. Avalon – Sensors for TPMS.
Toyota uses either direct or indirect TPMS.
Through the ABS system, indirect TPMS systems transmit tire pressure. Toyota transitioned to a direct TPMS system in February 2006, in which TPMS sensors are used to transmit tire pressure information.
How do Toyota tire pressure sensors function?
A sensor is located inside each of your tires and is fastened to the valve stem. It is battery-operated and uses radio frequency ID to broadcast your tire pressure (RFID). The RFID from each of your tire pressure sensors is received by a module. Each sensor’s pressure data is compared to a permissible threshold.
Are there batteries within Toyota TPMS sensors?
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. The duration of the TPMS sensor batteries is difficult to predict because it depends on how many radio frequency broadcasts the sensors send out. 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.
Which automobiles have indirect TPMS?
Systems known as indirect tire pressure monitoring systems (TPMS) do not use air pressure sensors installed inside the tires. Instead, they use the wheel speed sensors of the Anti-lock Brake System (ABS) to compare relative wheel speeds in order to identify a low tire. A tire’s diameter significantly reduces as air is lost from it.
However, they are also less expensive. Older indirect TPMS are less sensitive to changes in tire pressure than direct systems, which actually monitor the air pressure inside the tire. If a car already has ABS, adding an indirect TPMS is a reasonably priced addition. Even so, direct rather than indirect systems are used in the vast majority of vehicles with TPMS.
According to federal law, the TPMS must notify the driver if a tire’s internal pressure drops more than 25% below the suggested inflation pressure. Direct and indirect TPMS are subject to the same regulations. To comply with the government requirement, many automobiles switched from indirect systems to direct systems.
One of the drawbacks of older indirect systems is that if all the tires are similarly underinflated, the warning light might not come on. The system won’t detect an issue if all the tires are 24 psi (down 25%) when the recommended pressure is 32 psi since when the car is moving, all the tires will be rotating at the same pace.
For indirect systems to function, new systems make use of improved wheel speed sensors and modules. 2011 saw the return of indirect TPMS on all Audi vehicles. For the 2013 model year, the wildly popular Honda Accord made the switch to an indirect TPMS. An indirect TPMS is now also used by the 2013 Mazda CX-5. A few vehicles built on the VW Golf chassis now incorporate an indirect TPMS. The ABS and stability control systems are optional on the majority of these vehicles.
However, even more recent systems have the drawback of being unable to read tire pressure while the car is motionless.
Applications for indirect TPMS include:
- 2013–2014 Mazda CX-5
- VW GTI models from 2007 and 2010
- 2004–2006 Toyota Solara
- 2004–2007 MINI Cooper
- 2005–2007 Toyota Corolla
- 2004–2006 Lexus LS430
- Audi 2011-’14
- 2005–2007 Volkswagen Jetta
- 2004–2006 Toyota Highlander
- 2005–2006 Toyota Matrix
- 2004–2006 Lexus RX330
- Accord Honda 2013–2014
- 2004–2005 Toyota RAV4
- 2007 Mercedes-Benz C-Class
- 2005–2007 Mercedes SLK
- BMW X5 2002-’05
How is a Toyota tire pressure sensor calibrated?
When the tire pressure light blinks three times, release pressure on the TPMS reset button. Start the car and let it run for 20 minutes to let the sensor reset. Under the steering wheel is typically where you’ll find the reset button for the tire pressure monitor.
Do spare tires for Toyotas have TPMS?
A tire pressure warning light that illuminates when it detects a change in tire pressure is standard equipment on the majority of new Toyota vehicles, model years 2003 and newer. Rapid and severe temperature variations, which in Vermont tend to coincide with seasonal changes, are the ones that cause tire pressures to fluctuate the greatest.
The Toyota Tire Pressure Monitoring System (TPMS), which is mounted on the tire valves, is intended to alert you when any of the five (yes, FIVE!) tires on your car are underinflated. Low tire pressure in the spare tire of the car is the most typical cause of the warning light to come on. The majority of customers are not aware that their spare tire has a tire pressure monitor put in it, and that donut spares do not have a TPMS fitted. The light could also come on if a tire is ruptured, alerting you to an impending flat tire.
If you’ve examined all five tires and found that they are all properly inflated and free of punctures, it’s still conceivable that your TPMS is broken or otherwise not working properly. Incorrect inflation or damage sustained during a tire installation and balancing, most frequently when carried out by a technician who is not familiar with the system, might result in a broken TPMS. If you believe this to be the case, call or visit Heritage Toyota Scion right away, and one of our staff members will be happy to diagnose the issue and, if required, replace the malfunctioning sensors.
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. You are breaking the NHTSA’s “make inoperative provision” if you switch off the light without resolving the problem, which makes shops liable for deactivating 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.
Can I use OBD2 to reset the TPMS?
There are many various TPMS reset tools available. You may need to use a TPMS reset tool to reprogram the sensors if they have lost their information in some circumstances. You may frequently just push a button to reset the TPMS light with a TPMS reset tool. I suggest the Autel TS401 MaxiTPMS Activation Tool Link from Amazon if you’re interested in purchasing a tool like this. If you have a reliable OBD2 scanner, you can also use it to reset the TPMS light. Before making a purchase, always make sure the tools are compatible with your car.
Should the TPMS be reset after purchasing new tires?
After changing or rotating your tires, or after adding new sensors, you should always reset your TPMS. Even after you have inflated your tires, some sensor manufacturers advise restarting the device. By teaching the primary TPMS system to identify the sensors in their new locations, resetting the TPMS is frequently referred to as retraining the system. TPMS reset procedures vary from vehicle to vehicle and typically involve a specific sequence of ignition and pedal actions, a configuration change in your dashboard menu, or the use of a TPMS Reset Tool.
Toyota tire pressure sensors: how long do they last?
The TPS batteries last between three and five years, according to our experience here at the Lake Charles Toyota Service Center. If any of your sensors malfunction within the first three years, the manufacturer’s guarantee can still apply, according to service manager Kenny Guillory.
Does programming be required for tire pressure sensors?
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 that there are aftermarket TPMS sensors available that are “programmable,” “universal,” or “cloneable sensor units. 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.
