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.
I need to reset my 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.
On a Toyota Camry, where is the TPMS reset button located?
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.
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:
Why won’t the tire pressure warning light come on?
Try the following if your TPMS light is still on after you have inflated your tires to the recommended pressure: 10 minutes at a speed of 50 mph would be plenty. When you start the car again, the TPMS light ought to be off because this ought to reset the tire sensors.
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.
How much does it cost to fix a tire pressure sensor?
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.
Heres how tire pressure sensors work:
- 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.
AutoZone is able to check TPMS sensors.
You can determine if your tire pressure monitoring system is corroding or failing within your wheel with routine inspection; if so, you will need to replace it. Every tire pressure monitoring system item you require for your repair is available at AutoZone, guaranteeing that you can drive again efficiently and safely.
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.
Does the spare tire on a Toyota Camry feature TPMS?
Toyota automobiles with spare tires and TPMS 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.
What could activate the TPMS light?
Do you know what to do when the TPMS symbol for low tire pressure illuminates? The first step is to physically gauge your tire pressures and add air as necessary to bring them up to the manufacturer’s recommended levels. (The owner’s handbook or the driver’s door jamb will have the proper pressure; the sidewall of the tire will only have the tire’s maximum pressure.) Remember that your TPMS does not substitute for regular tire pressure checks. It is a gadget that can assist in notifying you when pressure is low, but a tire may deflate below the recommended level long before the TPMS warning light illuminates. When the tire pressure is either too low or too high, the TPMS light illuminates.
TPMS LIGHT ILLUMINATES WHILE DRIVING
At least one of your tires has low air pressure if your TPMS light illuminates and stays lit. Utilizing a gauge, check the pressure in each tire, identify the reason for pressure loss, and repair or add air to the tire(s) as necessary.
TPMS LIGHT GOES ON AND OFF
Variable temperatures may be causing your TPMS light to turn on and off when your tire pressure(s) is/are close to the level that generates an alert. The indicator may turn out when pressure increases during the day due to rising ambient temperature and/or heat produced by operating the vehicle; this often happens when pressure lowers at night due to a drop in ambient temperature. Check the pressure in each tire using a gauge and add air to any that need it.
TPMS LIGHT FLASHES AND THEN STAYS ON
Every time you start your car, if the light flashes for 60 to 90 seconds before staying on, it signifies the TPMS isn’t working properly. You should take your automobile to an auto repair shop for a checkup. The TPMS is malfunctioning and unable to alert you to low tire pressure until it is fixed. Using a gauge, check the tire pressure on all of them, and add air to the ones that require it.
In what location is the TPMS sensor?
In the US, direct TPMS usage is more prevalent. The sensors are either housed in the tire pressure valve, which also serves as an antenna, or they are band-clamped to the wheel rim. These gadgets deliver the data to an on-board computer.
The TPMS reset button is where?
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.
