Yamaha Warrior 350 Tire Pressure Sensor Reset

The tire pressure monitoring system (TPMS) in the Yamaha Warrior 350 is designed to alert you when tire pressure is below the recommended levels. If the TPMS light is flashing, it indicates a problem with the tire pressure sensors or that the tire pressure needs adjustment. Resetting the tire pressure sensor is essential to ensure accurate readings and maintain optimal performance.

To reset the tire pressure sensor on your Yamaha Warrior 350, follow these steps:

Steps to Reset Tire Pressure Sensor


  1. Ensure that all tires are inflated to the recommended pressure.

  2. Turn the ignition key to the “ON” position without starting the engine.

  3. Locate the TPMS reset button, usually found beneath the steering column or near the driver’s side panel.

  4. Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.

  5. Start the engine and check if the TPMS light remains off.

Troubleshooting a Flashing TPMS Light

If the TPMS light continues to flash after resetting, consider the following troubleshooting steps:


  • Check for any visible damage to the tires or rims.

  • Inspect the tire pressure in all four tires, ensuring they are at the correct levels.

  • Examine the TPMS sensors for any signs of malfunction or battery issues.

  • Consult the Yamaha Warrior 350 owner’s manual for specific troubleshooting guidelines.

Flashing Light Sensor malfunction or low tire pressure.
Steady Light One or more tires are below the recommended pressure.
No Light All tires are properly inflated and sensors are functioning.

Importance of Maintaining Proper Tire Pressure

Proper tire pressure is vital for the overall performance and safety of your Yamaha Warrior 350. Maintaining the correct pressure ensures optimal traction, handling, and fuel efficiency. Under-inflated or over-inflated tires can lead to various issues, including uneven tire wear, compromised handling, and increased risk of tire blowouts.

Benefits of Correct Tire Pressure


  • Improved Safety: Properly inflated tires provide better grip on the road, reducing the likelihood of skidding or losing control.

  • Enhanced Fuel Efficiency: Correct tire pressure minimizes rolling resistance, leading to better fuel economy.

  • Longer Tire Life: Maintaining the recommended tire pressure helps prevent premature tire wear, extending their lifespan.

  • Better Ride Comfort: Properly inflated tires absorb shocks better, providing a smoother ride.

How to Check Tire Pressure

Regularly checking your tire pressure is crucial for maintaining optimal performance. Here’s how you can do it:


  1. Purchase a reliable tire pressure gauge, either digital or analog.

  2. Ensure the tires are cold, as heat from driving can increase the pressure reading.

  3. Remove the valve cap from the tire you want to check.

  4. Press the tire pressure gauge onto the valve stem firmly to get a reading.

  5. Compare the reading to the recommended tire pressure listed in your owner’s manual or on the tire placard.

  6. If the pressure is too low, inflate the tire to the recommended level. If it’s too high, release some air until it reaches the correct pressure.

  7. Replace the valve cap securely after checking.

Useful Tips for Maintaining Tire Pressure


  • Check tire pressure at least once a month and before long trips.

  • Inspect your tires for any signs of damage or wear regularly.

  • Keep a portable air compressor handy for quick inflation when needed.

  • Consider using nitrogen instead of regular air to fill your tires, as it maintains pressure longer.

  • Be aware of seasonal changes, as temperatures can affect tire pressure significantly.

By prioritizing proper tire pressure maintenance, you ensure a safer, more efficient, and enjoyable riding experience on your Yamaha Warrior 350.
