A sensor must be changed if it turns out to be defective or damaged. This necessitates the installation of a new sensor and the programming of the ECU with the new sensor’s specific ID and location on the vehicle. The Bartec Mitchell1 “Tire Pressure Monitoring Systems Guide” provides servicing requirements, reset instructions, mounting/dismounting instructions, torque parameters, and other information for all Toyota models and years. It also illustrates the procedures for all cars.
The technician should always: use new grommets, nuts, plastic or nickel-plated valve caps, and electro-less, nickel-plated valve cores when doing any tire service; consult the manufacturer’s instructions for the correct torque requirements when replacing nuts and valve cores; Never combine an aluminum TPMS sensor stem with a brass valve core or unplated brass cap. Galvanic corrosion, which can result in air pressure loss, can be brought on by contact between metals that are not compatible.
Note: The technician should refrain from injecting any liquid or tire sealant into tires that have TPMS because doing so could obstruct the pressure port and result in malfunction. It is strongly advised that the TPMS be changed if tire dismounting reveals signs of tire sealant use. Prior to reinstalling the tire on the Toyota car, it is crucial to clean any leftover sealant from the interior of the tire and the rim surfaces.
Contrary to the majority of North American-made cars, the Toyota line of vehicles lacks an in-built relearn mode that would allow the vehicles to relearn the TPMS IDs when a TPMS repair tool is used to activate the sensor. It is crucial to have access to a Bartec Tech600Pro tool that can diagnose Toyota TPMS problems and has an additional OBDII/CANbus interface to connect to the vehicle’s Engine Control Unit (ECU) and download TPMS data. This feature is present in the Tech600Pro.
To make sure the right part is installed, the tool can display the Service kit number and the replacement item number for the TPMS sensor. The TPMS warning light can be turned off and the car can be programmed!
Finally, it is best practice to conduct a final audit when the TPMS replacement procedure is finished and print the results for the customer. This completes the circle for your liability protection (demonstrating that the work was done professionally) and establishes your technical credibility with the client.

Can I change the TPMS sensors on my own?
Rubber-stemmed, snap-in TPMS sensors are just as simple to change as regular valve stems. No unique equipment is required. Hex nut stems must, however, be meticulously tightened to a precise value using a TPMS valve stem tool or an exact inch-pound torque wrench.
How much does a Toyota tire pressure sensor replacement cost?
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.
How can I fix the tire pressure sensor in my Toyota?
When the Toyota tire pressure sensor blinks three times, hold down the TPMS reset button until it stops blinking. Start the car, then let it run for 20 minutes to let the sensor reset. Under the steering wheel is typically where you’ll find the TPMS reset button. Consult the owner’s manual for your car if you can’t find it.
How much will a new TPMS sensor cost?
Replacement of a TPMS sensor typically costs between $203 and $245. While parts are priced between $149 and $177, labor costs are predicted to be between $54 and $68. Taxes and other costs are not included in this range, nor are your particular vehicle or geographic area taken into account.
Toyota TPMS sensors: how long do they last?
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.
Can TPMS be changed at a tire shop?
The sensors used in tire pressure monitoring systems are attached to the wheels or the valve stems, and they can become worn down over time or be harmed by debris, the elements, or potholes. Additionally, TPMS electronics are susceptible to failure. When the sensors or other components of the system aren’t working properly, the TPMS warning light is meant to flash; if the light is indicating that a tire needs more air, it should just stay on. If a warning light or message appears, consult your owner’s manual to see what it signifies.
The sensors send radio signals to a control unit, and occasionally other radio transmissions using the same frequency interfere with the TPMS signals, resulting in a malfunction notice.
After changing or installing new tires or wheels, the majority of tire stores and repair facilities advise servicing the TPMS by changing the valve core, retaining nut, seal, and valve stem cap, followed by testing the system to ensure it is functioning properly. The TPMS on many vehicles needs to be electronically reset following a tire change or replacement. On others, if the sensors are working properly, a few miles of driving will automatically reset the system.
There are two varieties of TPMS: direct and indirect. The more advanced direct type monitors each tire’s air pressure (including the spare tire on some models) and indicates which tire is low on air on the dashboard display. There are numerous direct technologies that can show the actual tire pressure.
The indirect kind measures wheel speed using antilock brake sensors. The warning light will turn on because an underinflated tire will rotate the wheel more quickly than one that is completely inflated. If a sensor detects an issue, you must inspect every tire because indirect systems typically don’t indicate which tire is underinflated.
Because tire pressure frequently decreases as the temperature rises, cold weather might set off a warning light on either type of system. After the car has been driven a while and the tire pressure has risen, the warning light can turn off.
Because the sealant kits could harm the TPMS sensors, some manufacturers advise against using them to fix flat tires. A tire pressure gauge should be used to check tire pressure manually at least once every month, according to tire experts. In comparison to fully inflated tires, underinflated tires have a shorter lifespan, less traction, and a reduced capacity for carrying loads. Additionally, low tire pressure might decrease fuel efficiency. Even though a TPMS light should alert you to any issues, it is always a good idea to perform manual checks in case the tire pressure sensors are not working properly.
What is the turnaround time for a tire sensor replacement?
It may take 10 minutes to an hour to replace a tire pressure sensor. If you are unfamiliar with the equipment, it is advised that a professional replace your tire sensor.
Does the Toyota TPMS require programming?
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.
Who can swap out the TPMS sensors?
Based on the expected lifespan of your new tires, your neighborhood Midas specialist may assist you in determining whether to update your TPMS sensors. When that time comes, we’ll be there to repair your sensors.
Is Walmart able to swap out TPMS sensors?
Your automobile has a safety system that may identify low tire pressure and alert you in advance. Your tire pressure is checked and inflated using the Walmart Tire Pressure Monitoring System service. The answer is yes if you’re wondering whether Walmart installs TPMS. Depending on the TPMS you select, Walmart may install TPMS sensors for anywhere between $10 and $30.
Why are the tires fine but the TPMS light is on?
It’s likely that one or more of your tires have low air pressure if you see the tire pressure indicator turn on. However, even if your tires are in good condition, there are a number of things that could cause the sensors to go off, so you shouldn’t rely only on the data from the tire pressure monitoring system of your car.
