Turn the engine switch to the ON position or the ENGINE START STOP switch to IGNITION ON mode (for vehicles with smart key systems) to reset the tire pressure monitoring sensors. In your Toyota Yaris, press and hold the button just below the steering wheel until the tire pressure warning light gently blinks three times. Your TPMS will be reset by this. The lights will turn on if your tire pressure is less than 25% of the prescribed value. Using the same tire gauge, check the air pressure in your tires once a month. A blowout may result from low tire pressure.

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.”

Direct vs. Indirect TPMS systems
Before beginning any repairs on a Toyota Yaris, “CHECK TPM” should be carried out. The tool will be able to show if the car was made with a direct or indirect system using the VT56 or VT46 brands.
- Choose GOLF and VOLKSWAGEN (brand of vehicle).
- CHECK TPM can be found on the main menu.
- The tool will reveal whether the car is an indirect system from the YEAR menu.
When changing air pressure, rotating tires, or replacing a TPMS sensor, an indirect relearn should be carried out if the vehicle has an indirect system, which means there are no sensors in the wheel.
Where is the Toyota Yaris’ TPMS reset button?
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.
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.
Why, Toyota, does my tire pressure light remain on even after filling the tires?
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.
My Toyota TPMS has to be reset.
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.
My tires are in good condition, so why is my low tire pressure sign on?
Typically, a tire with an air pressure that is 10% to 15% low will turn on the warning light. The air pressure inside the tires also tends to drop in cold or icy conditions. Short trips in the car will warm up the tires and raise the pressure in them.
How can I make my low tire pressure warning light come on?
How to Clear the Tire Pressure Indicator
- Don’t start the car; just turn the key to “on.”
- While the car is off, disconnect the positive battery cable.
- All tires, including the spare, should be 3 PSI overinflated before being entirely deflated.
- Bring your car to our service department for qualified help.
Why is the pressure in my tires light still on?
When the TPMS warning light illuminates, proceed with caution. This indicates that at least one of your tires may be at least 25% under-inflated.
*The simplest way to get the most accurate reading is to check the tire pressure before you drive on it when the tire is “cool.” If your TPMS light is on, first check that you have correctly reset your TPMS by following these instructions.
Will my TPMS light automatically turn off if I fill my tires with air after it illuminates?
Several minutes after reinflating the tires to the prescribed pressure, the TPMS light ought to go out.
What happens if I adjust the tire pressure but the light on my tire pressure gauge still doesn’t go out?
The only place that can fix a computer issue that causes the TPMS warning light to turn ON and flash ON for one second and OFF for three seconds is the dealership service center. When the TPMS warning light illuminates and remains on, one or more tires may have low tire pressure. The light ought to go out once the tire is inflated to the recommended tire pressure listed on the door placard. Always check the pressure in all of your tires because one or more of them may not be at the proper pressure.
What is the Toyota Yaris’ recommended tire pressure?
According to this tire placard, the Toyota Yaris should have 33 psi of minimum tire pressure. This is equivalent to 2.3bar and 230kPa.
Compromised Safety
Driving with overinflated tires can lead to a number of problems. Most significantly, blowouts are more likely with overinflated tires. A tire blowout puts you and other drivers on the road in danger because it can make you lose control of your car and shorten your stopping distance.
Furthermore, many of the safety features on your car, like the anti-lock brake system, are made to function when the tires are inflated according to the manufacturer’s specifications. Tires that are overinflated may jeopardize several of your car’s driver assistance features.
Tire Damage and Wear
Your tires may become more susceptible to damage if you overinflate them. Tires that are fully inflated are more rigid and inflexible, similar to an overfilled balloon, and are therefore more prone to damage from potholes, curbs, or debris. You will also feel every dip and bump in the road as a driver or passenger, which doesn’t make for a comfortable ride.
In addition to changing the tire’s shape, excessive air pressure can cause wear and tear in the tire’s center and reduce traction. Tires that have been frequently overinflated may deteriorate more quickly depending on the situation.
When a tire is overinflated, the tread bulges in the middle. Only a thin, central portion of the tire is in contact with the surface of the road. According to Popular Mechanics, in principle, “this should mean less rolling resistance and increased mileage.” But in practice? It entails higher chance of a blowout, uncomfortable riding, and center tread wear.
Keep in mind that typically speaking, a few PSI over the recommended tire pressure won’t put you in danger. After all, tire pressure varies depending on the weather. Your objective is to maintain the recommended cold tire pressure for your vehicle.
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.
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.
How long before the tire pressure light appears?
After a few kilometers of driving, the light may turn off if the tires are adequately inflated. After around 10 miles, if the light still remains on, it may be necessary to reset the TPMS as instructed in the owner’s handbook of the car.
Can the tire pressure monitoring system be turned off?
On the gauge cluster of your car’s dashboard, a horseshoe-shaped emblem with an exclamation point lights when your tire is underinflated. The tire pressure monitoring system is the piece of equipment that generates this signal.
Sensors provide the TPMS with data on the air pressure level. The air pressure sensors inside your tires or the anti-lock brake system’s wheel speed sensors may be used by your car’s TPMS, depending on the model.
