Early in the 2000s, the Tire Pressure Monitoring System, or TPMS, was introduced. As of 2008, it was required to be installed on all models sold in the United States. You can bet that you will eventually run into a problem with this system if your car is a 2008 model or newer.
To find a tire pressure loss of more than 25% of the permissible pressure, there are primarily two types of technologies employed.
- Indirect Systems: Indirect Systems don’t employ TPMS sensors; instead, they operate through the ABS module. The computer analyzes the data coming from the wheel speed sensors at each wheel. The wheel speed is proportionally impacted when a tire loses pressure. In this manner, the computer can identify the low tire and turn on a warning signal or message.
- Direct Systems: Direct systems work with sensors at each wheel that send radio frequency signals to a receiver positioned inside the car. This signal contains data on temperature, tire pressure, and sensor battery life. These will either be low line or high line systems. The direct high line system places several receivers next to each wheel and can tell the driver of specifics on each individual tire. The driver must inspect all of the tires to identify which ones are low as the straight low line system only indicates that one tire is low.
There are two frequencies used by TPMS sensors: 315 MHz and 433 MHz. The maker of the vehicle chooses the sensor’s resonant frequency. The two frequencies cannot be switched between. The sensor’s outside will bear this information displayed in large letters. By reviewing the service handbook or removing the sensor, you must establish the proper frequency for your car.
TPMS sensors are often required by automakers from a certain OE supplier, which can change from model to model. A lack of operation will come from using the wrong sensor.
The VDO REDI-Sensor is one example of an aftermarket sensor that is made to include a number of algorithms that work with different vehicle platforms. Other aftermarket sensors are created to function on many platforms, but they need to be programmed to talk to the car using a unique ID number that is assigned to each sensor by a specific programming tool. This approach is used by sensors like the Dorman MULTi-FIT.
In an effort to prolong battery life, new sensors are sent in storage mode. There are various ways to awaken the sensor so that it can start serving its purpose, depending on the sensor’s manufacturer.
- Radio Transmission: A TPMS activation tool must transmit a signal at a frequency of 125KHz to some sensors. Most sensors can be activated using a tool that works with different types of sensors and automobiles. TRW sensors require a special modulated 125KHz transmission signal, which typically requires the activation equipment made by the particular car manufacturer.
- Some sensors can be activated by pressure as little as 25 psi in order to exit their storage mode. This means that following a quick installation and tire inflation, they are ready to use.
Every sensor has a distinct sensor ID that can be seen in either decimal or hexadecimal notation. Using a programming calculator, one format can be changed into the other. The relearn procedure must be started in order to register this number to the car. As a result, the unique sensor identification number is assigned. There are many various kinds of processes, and each one is specific to the manufacturer and type of vehicle.
- Some systems will immediately figure out the new sensor’s ID and where it is on the car. For roughly 15 minutes, the car is driven at a speed greater than 12 mph. Once the sensors are found, the computer will turn off the warning.
- Manual Entry: Using a factory-compatible scan instrument, the sensor ID must be manually recorded and input into the computer. The sensor is given a precise wheel position during this process.
Tool of Activation It switches the computer into training mode. After then, each sensor is assigned to the car using an activation tool, starting at the left front wheel and moving clockwise around the vehicle to each succeeding wheel. To upload the sensor IDs to the computer on some models, the activation tool may be connected to the DLC.
Magnet for Activation The computer is switched to training mode, and the valve stem is covered with a certain circular activation magnet. This enables the computer to store the sensor ID.
The TPMS system might need to be initialized if the tires are rotated or the tire pressure is changed. You can do this by pushing a button inside the car or by going to a menu on the driver information display. Some systems demand that the car be driven for a brief length of time above a specific speed.
Repairing your TPMS doesn’t have to be a nightmare. Before doing any diagnostic procedures or replacing any parts, be sure you fully comprehend how your system works.

Do Toyota TPMS need to be programmed?
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.
Can TPMS sensors be switched from one tire to another?
The quick answer is that you can use your old TPMS on your new wheels and tires, but we’ll go through some other things to think about below.
On new wheels, can I repurpose my TPMS sensors?
Your factory-installed tire pressure monitoring sensors can absolutely be reused. Please be careful when removing the sensors from your wheels because they are delicate and easily broken. The complete unit may need to be replaced if the sensor or valve stem sustain any form of damage.
How do I choose the right TPMS sensor?
The best approach to determine whether the TPMS sensor that is currently in place is accurate is to observe how it is positioned in the rim. The sensor should not be positioned over the rim when it is put “security hump Should the sensor be “If you’re flying in the air, you should think about using an adjustable (flexible) angled sensor. The location of the valve hole is something else you should pay attention to. You should take into account the 90-degree valve options that are already on the market if the valve hole is in the center of the rim and/or at a 90-degree angle. If you are repairing black rims, there are also black anodized stem alternatives available. When dealing with aftermarket sensors and rim sets, you can discover that you have more options. Before continuing, gather them and go over preferences with the client.
Can any TPMS sensor be used on any vehicle?
The majority of businesses carry more than one sensor brand to operate on any vehicle that comes in for TPMS servicing for the best vehicle coverage. Because there are so many variants of TPMS sensors available in the aftermarket, technicians need be aware of their options in order to select the best one.
OEM sensors are a direct replacement for sensors that were initially produced. Since the IDs have already been written to the sensor, installation does not need configuration of the device.
The aftermarket universal TPMS sensors are programmable or configurable. Before using the sensor, a TPMS tool must be used to program it or copy it from an OEM or another aftermarket sensor.
- Standard Qwik, NAPA Qwik, Schrader EZ-sensor, Orange Universal, MAX T.O.T.A.L., Mobiletron, PDQ, Steelman Select, U-Pro, Myers U-Pro, HUF Intellisens, and Dynamic Pro-Select are some examples of quick sensors.
Multi-protocol TPMS sensors are aftermarket devices that include a selection of sensor protocols pre-installed. It is a replacement part for part. It is not necessary to configure the sensor before usage because the IDs have already been written to it.
One-to-one TPMS sensors are aftermarket devices that directly replace an original equipment sensor with a sensor protocol that has already been preloaded. It is not necessary to configure the IDs before usage because they are written to the sensor.
Orange Direct Fit, Dill OE, Standard OE, and NAPA OE-Design.
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.
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.
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 on in lieu of the valve stem caps.
How much does reprogramming a TPMS cost?
Tire pressure monitoring system retraining typically costs between $35 and $44. Between $35 and $44 is the expected labor cost range. Taxes and other costs are not included in this range, nor are your particular vehicle or geographic area taken into account.
Do I need to swap out all 4 TPMS sensors at once?
The valve stem houses the TPMS sensors. A non-issue unless your wheel was harmed. It is unlikely that all four tires need to be replaced. All four wheels are supposed to be moving at various rates thanks to differentials.
