Our goal is to empower Yaris owners with the knowledge to confidently maintain their TPMS for optimal performance and safety.<>

Understanding the Toyota Yaris TPMS

The tire pressure monitoring system (TPMS) on the Toyota Yaris uses wheel-mounted sensors to measure the air pressure in each tire. If the pressure in one or more tires drops below a preset threshold, typically 25% below the recommended pressure, the system will alert the driver by turning on the TPMS warning light.<>

There are two main types of TPMS: direct and indirect. Toyota Yaris models are equipped with a direct TPMS, which has a sensor mounted on each wheel that actively measures the tire pressure. Some advantages of direct TPMS include:<>

• More accurate pressure readings
• Ability to display real-time tire pressure for each wheel
• Faster detection of sudden pressure loss (e.g. puncture)

Why You Need to Reset and Relearn TPMS

There are a few scenarios when you’ll need to reset and relearn the TPMS on your Toyota Yaris:<>

1. After rotating the tires: The TPMS needs to relearn the position of each sensor
2. After replacing one or more sensors: The system must learn the new sensor IDs
3. When the TPMS warning light comes on: Resetting the system may resolve the issue if tire pressures are correct
4. When changing between summer/winter tires: Allows the system to monitor the second set of sensors

Performing a TPMS reset and relearn ensures the system is monitoring the correct tires/wheels so it can provide accurate low pressure warnings and maintain your safety on the road.<>

Resetting TPMS After Rotating or Adjusting Tire Pressure

The process to reset the TPMS after a tire rotation or pressure adjustment is straightforward on most Toyota Yaris models:<>

1. Ensure all tires are inflated to the pressure listed on the placard inside the driver’s door jamb.
2. Turn the ignition to the “ON” position without starting the engine.
3. Locate the TPMS reset button. It’s usually found under the steering wheel, driver’s side knee bolster area, or inside the glove box. Look for a small black or yellow button.
4. Press and hold the reset button until the TPMS warning light on the dash blinks slowly 3 times.
5. Start the engine. The warning light should turn off within a few minutes as the system completes the relearn process. If the light remains on, try repeating the procedure or driving the vehicle for 10-20 minutes.

Some older Yaris models may not have a dedicated TPMS reset button. In that case, the relearn process is initiated through a sequence of ignition and button presses. Consult your owner’s manual for specific instructions.<>

Relearning TPMS After Installing New Sensors

If you’ve replaced a damaged TPMS sensor or upgraded to a newer style, the system needs to learn the new sensor ID(s) before it can function properly. This process requires a TPMS activation tool and a scan tool or dedicated TPMS relearn tool.<>

Using a Scan Tool (OBD):

1. Connect a TPMS-enabled scan tool to the OBD-II port under the Yaris’ dash.
2. Select the TPMS relearn function on the scan tool menu.
3. Starting with the left front tire, use a TPMS activation tool to trigger the sensor.
4. The scan tool will detect the new sensor ID. Repeat for the other three sensors in a clockwise pattern.
5. Once all new sensor IDs are registered, turn the ignition to “ON” and press the TPMS reset button to complete the relearn.

Using a TPMS Relearn Tool:

1. Turn the ignition to the “ON” position.
2. Connect the TPMS relearn tool to the OBD-II port.
3. Activate each sensor with a TPMS trigger tool, starting with the left front in a clockwise pattern.
4. The relearn tool will confirm when all sensor IDs have been successfully registered to the vehicle.

It’s recommended to have new TPMS sensors installed and relearned by a professional shop with the proper tools to ensure the job is done correctly. An incomplete relearn can result in the TPMS light remaining on.<>

Reasons Why the TPMS Warning Light Comes On

The TPMS warning light on your Toyota Yaris can illuminate for several reasons:<>

1. Low tire pressure: One or more tires is significantly underinflated
2. Spare tire in use: Compact spare tires don’t have TPMS sensors
3. Sensor damage: A sensor may have been damaged from impact or corrosion
4. Sensor battery died: TPMS sensor batteries last around 5-10 years
5. System malfunction: An issue with the TPMS module or wiring
6. Extreme temperature changes: Tire pressure decreases in cold weather

If the TPMS light comes on while driving, safely pull over and check the pressure in all tires with a gauge. If a tire is low, inflate it to the proper pressure. The warning light should turn off once you’ve driven a few miles if the low pressure was the culprit. If the light persists or comes on again soon, there may be a leak or TPMS component issue that needs to be addressed.<>

Frequently Asked Questions About Toyota Yaris TPMS

Can I drive with the TPMS light on?

It’s not advisable to continue driving with the TPMS warning light illuminated.
