To warn of low tire pressure on any of the vehicle’s four or five tires, Toyota automobiles are equipped with TPMS, or a Tire Pressure Monitoring System. According to the table below, a TPMS from one of two manufacturers is installed as a component of the valve assembly in every Toyota vehicle.
The tire pressure monitor ECU/receiver receives the data from the sensor, which detects the pressure and temperature inside the tire, together with the TPMS’s distinctive ID.
If the TPMS ID is stored with the ECU, the placard pressure is checked with it, and if there is a pressure difference, a warning light is illuminated on the dash-mounted display. Toyota TPWS, which stands for “Tire Pressure Warning System,” is another name for Toyota TPMS.

What does TPWS on my automobile stand for?
Here are some of the causes of your Toyota Camry’s “Toyota refers to it as Tire Pressure Warning System alert. It shall be referred to as “TPWS from this point on. If your TPWS system warning light is on right now, check your tire pressure right away before we start.
How can I reset the TPMS sensor on my Toyota?
Resetting the Tire Pressure Light on a Toyota Turn the key to the “On position when the car is off, but don’t let it run. 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.
How do I reset TPWS?
Turn the key to the “on” position with the car off, but don’t let it run. 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.
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.
Can I drive with my TPMS on?
There are several possible meanings when you see that silly little light with the exclamation point glaring back at you. It’s frequently anything as harmless as temperature changes that result in a change in the tire’s air pressure. In more severe situations, a puncture or other damage has caused the tire to lose pressure. The sensor can also be activated and result in the light coming on if your tires are overinflated.
Is It Safe To Drive With TPMS Light On?
To avoid seeming like Debbie Downer, we’ll simply say no. Driving around with your TPMS light on is not safe. You can’t tell how quickly your tire is losing air or how long it has been over- or underinflated without doing a tire examination. The best course of action is to check the current inflation level of each tire with a tire pressure gauge.
When the tire inspection light appears while you are driving, slow down and get to the closest gas station or service facility.
Can I drive for how long with the tire pressure light on?
The air will frequently warm up and expand after 20 minutes of driving, restoring the proper pressure in your tires. After 20 minutes of driving, if the light is still on, you should add air to your tires as necessary to restore the proper pressure. Whatever the source, low tire pressure is dangerous for your car.
Why are my tires fine but my 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.
We’ve talked about some additional aspects of automobile maintenance in this piece. Read these articles if you have some time:
Where is the button to reset my TPMS?
Tire pressure monitoring system is referred to as TPMS. The TPMS reset button is often located below the steering wheel. Your car’s TPMS needs to be electronically reset after you replace the tires in order to erase the error message. Hold the TPMS reset button down until the tire pressure light blinks three times, then let go of the button to complete the process. Your car should be started, and the sensor will refresh after 20 minutes.
How much does a tire pressure sensor repair cost?
Since 2007, tire sensors have been a requirement for all car models as valuable diagnostic tools. Fortunately, depending on your automobile type, repairing a tire pressure sensor normally costs between $80-$140.
The cost of repairing a sensor can be paid if your cars are still covered under warranty. If you think this applies to you, check with your dealership.
Tire pressure sensors operate as follows:
- In addition to making driving safer, properly inflated tires also yield improved gas mileage.
- The sensors inform your car’s computer about the tire pressure by sending a signal. If the light comes on, make sure you check your tire pressure. It might indicate a leak or even that your tires are overinflated.

What occurs if the TPMS battery runs out?
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 malfunctions a tire pressure sensor?
A problem with the tire pressure monitoring system is indicated by the message “Tire Pressure Sensor Fault.” Most likely, a tire pressure sensor or the connection to the sensor has a problem.
The air pressure in the tires may be too low or high, or one of the tire pressure sensors may be broken, according to the error code.
Incorrect wiring, a malfunctioning TPMS control unit, or a TPMS reset could potentially be at blame. The quickest approach to learn is to use an OBD2 scanner to read the fault codes from your TPMS control unit.
