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.

TPMS reset button, closed loop
A “SET” or “TPMS RESET button can be found on some Toyota vehicles and is either under the glove box or beneath the steering wheel. The system searches for the already-stored sensor IDs when the button is pressed. The “SET button can be utilized while replacing tires, changing or altering tire pressure, changing tire size, or conducting a tire rotation with differing tire pressures in the front and back.
The ECU must be unlocked in order for the relearn method to function properly if the “SET button is pushed after new sensor IDs are introduced but before a relearn is carried out. A few sophisticated TPMS diagnostic tools can unlock the ECU. You can successfully complete the relearn procedure if your TPMS scan tool offers the “UNLOCK ECU option.”
Toyota TPMS vehicles manufactured in the USA vs Japan
There are two choices for the Year from 2006 to 2011 when choosing the Make, Model, and Year of your car. Toyota Camrys that were sold in the US were initially produced in either the US or Japan. With the VT56, Quickset, or your diagnostic scan tool, it is crucial to choose the appropriate option of “2008 USA” or “2008 JAPAN” since there is a tiny difference in how the TPMS data is delivered to the vehicle’s ECU.
Examine the VIN barcode of the car, paying close attention to the first character, to determine if the Toyota Camry you are working with was made in Japan or the USA.
- “The number 1 denotes that the car was made in the USA.
- “J denotes that the car was made in Japan.
Toyota TPMS vehicles with spare tire
Since 2006, some Toyota Camry models have had the option to be purchased with a spare tire equipped with a TPMS sensor. To fully reset the system and write all of the TPMS IDs to the vehicle’s ECU, you must additionally engage the spare tire’s TPMS sensor during the relearn procedure. The TPMS light will continue show a TPMS MIL even if the spare tire is not in use. You will be given the option to select 4 or 5 tires after choosing the Make, Model, and Year. Check for the following signs to see if your Toyota Camry was manufactured with a spare tire:
- Does your car have a spare tire or donut? If there is a tire in the trunk, it needs to be placard-pressure inflated and equipped with a TPMS sensor.
- If there are no tires in the trunk, the size of the trunk usually indicates whether the vehicle was constructed. It most likely came with a spare tire when it was created if it appears like a full tire can fit in the trunk. If not, all that might be needed is a donut, which doesn’t need a TPMS sensor.
Left Front, Right Front, Right Rear, Left Rear, Spare Tire are in that order.
Indirect TPMS for Toyota Camry 2004-2006
In 2004, Toyota Camry introduced TPMS systems. They initially employed the indirect TPMS technology, which lacks sensors in the tire. 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.
High line vs. low line TPMS systems, Toyota Camry 2014-2019
The Toyota Camry features low line and high line TPMS systems from 2014 to 2019. When you reset the TPMS system, it is crucial to know which system you are using. The system won’t work properly and may display 0 PSI on the high-line system’s dash if the wrong sensor is placed, such as a low line TPMS sensor on a high line TPMS system car.
System for Low Line TPMS:
Low tire pressure is indicated by a low line TPMS system by the TPMS light alone. To check the tire pressure, you must use a tire pressure gauge or TPMS equipment. The light will remain on until the tire is fully inflated with the recommended quantity of air when the tire pressure is 25 percent underinflated. When you start your car, the light will flash for a minute if there is a system failure.
The tire pressure of each tire is shown on the dash or instrument display using a high-line TPMS system. The TPMS sensor will immediately tell the location of the sensor if there is a fault.
How does a TPMS sensor identify the correct tire?
The anti-lock brake system’s wheel speed sensors are often used by an indirect TPMS. On-board computer systems can employ these sensors to compare wheel revolution rates between individual wheels as well as to other vehicle operation data, such as speed.
The computer can determine the relative size of the tires on your car based on how quickly each wheel rotates. The computer determines that a tire is underinflated when a wheel starts spinning more quickly than normal and warns the driver accordingly.
Therefore, a device for monitoring tire pressure indirectly does not truly measure tire pressure. The same kind of measurement you may observe with a tire gauge is not being processed electronically. An indirect tire pressure monitor only counts the rotational speed of your tires and sends instructions to the computer to activate the indication light when something seems off with the rotation.
Does Toyota alert you to a low tire?
Tire Pressure Monitoring Systems are standard on all new Toyota vehicles (TPMS). Essentially, the system’s function is to inform drivers when a tire or tires are in need of being refilled, repaired, or replaced. Any queries customers may have about the TPMS in their Toyota car can be addressed by the service team here at Toyota Palo Alto. Come see how the Tire Pressure Monitoring System in Your Toyota Vehicle operates with our team today!
What Should You Do When the Tire Pressure Monitoring System Warning Light is Active?
In order to measure the tire pressure for each of the car’s four tires, the Tire Pressure Monitoring System in your Toyota vehicle essentially uses sensors. The TPMS Warning Light and a warning message will both illuminate on your Toyota instrument panel when one or more of your tires have too little air in them. Now, drivers should check the pressure in each of their four tires, and if required, fill them. If, after doing so, the warning light and message still appear, you should contact your neighborhood mechanic or a Toyota dealership to have the problem further investigated.
How Do You Reset the Tire Pressure Monitoring System?
Sometimes the alert will also appear after you rotate your tires, change your tire size, or adjust the tire pressure. In these situations, all you have to do is reset the TPMS to account for the modifications you made to your car’s tires. Simply press and hold the while the engine is running to reset the TPMS “Most Toyota models include a reset button on the instrument panel to the right of the steering wheel. Keep the “Press the reset button three times until the TPMS Warning Light blinks slowly. To finish the reset procedure, let the engine run for a few more minutes and then shut it off again.

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.
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.
What is the price of a Toyota tire sensor?
Tire pressure sensor replacement for a Toyota Corolla typically costs $99, which includes $4 for components and $95 for labor. Prices may change based on where you are.
What is TPMS?
Your car’s Tire Pressure Monitoring System (TMPS) is an electrical device that tracks the pressure in your tires and notifies you when it becomes dangerously low.
Why do vehicles have TPMS?
Congress passed the TREAD act, which mandates that the majority of vehicles built after 2006 be TPMS-equipped, in order to educate drivers about the significance of tire pressure safety and maintenance.
How does the Tire Pressure Monitoring System work?
Direct TPMS and Indirect TPMS are the two types of systems now in use.
Each tire’s air pressure is measured by Direct TPMS using a sensor located inside the wheel. The sensor notifies your car’s computer system when air pressure falls by 25% below the manufacturer’s suggested level, which activates your dashboard indicator light.
The wheel speed sensors of your car’s Antilock Braking System (ABS) function with indirect TPMS. Low tire pressure will cause a tire to roll with a slower wheel speed than the other tires. The dashboard indicator light is triggered when the computer system in your automobile detects this information.
What are the benefits of TPMS?
When the tire pressure in your car is low or starting to go flat, the TPMS alerts you. TPMS helps improve your vehicle’s handling, lessen tire wear, shorten stopping distances, and improve fuel efficiency by assisting you in maintaining optimum tire pressure.
Is my vehicle equipped with a Tire Pressure Monitoring System?
If the “low tire pressure” warning light comes on when the key is in the “on” position, your car has TPMS.
What should I do if my warning indicator comes on?
Check your tires’ air pressure and fill any that need it (as per the manufacturer’s recommendations). The indication light ought to turn off when the tire is inflated to the proper pressure.
Replace the tire if required, then head to your neighborhood Tires Plus store for any required repairs or replacements. To identify the issue, they’ll check the tire pressure on your car and run a systems test on each tire sensor. Our professionals will take care of your car’s tire issues and then recommend the right maintenance to get you back on the road safely.
Why does tire maintenance with Direct TPMS cost more?
Tires with a direct TPMS cost a little more to maintain because optimal care necessitates more parts and labor. When a tire is removed from its mounting for maintenance or replacement, the valve service kit, which consists of the valve core, cap, nut, and oring (seal), must always be replaced. To examine and reset the sensor system, you also need a special TPMS tool and more time.
How are the TPMS sensors powered?
The pressurized pocket created by a wheel and tire contains a small, programmable electrical device called a tire-pressure sensor that continuously checks the tire’s air pressure. The sensor uses low-frequency radio to send that data to the car’s onboard computer and, if it has one, a corresponding instrument cluster display. If one or more tires are low on air, it will glow an amber warning light and display the pressure in pounds per square inch (psi).
The so-called Tire Pressure Monitoring System depends on tire-pressure sensors (TPMS). Since becoming required in the US for the 2008 model year, millions of these devices have been installed in passenger vehicles. Batteries power the tire-pressure sensors, which are typically mounted to each tire’s valve-stem assembly.
