Why won’t my tire pressure light go off even though pressure is fine?
If you’ve added air but the air pressure warning light stays on, there’s a problem with your Tire Pressure Monitoring System or you have a slow leak. Quick Tip: If the TPMS warning light comes back on after you’ve filled the tire with air, recheck the tire to make sure it is inflated to the proper air pressure. The location of your vehicle’s tyre pressure monitoring system (often abbreviated to TPMS) reset button will vary depending on the make and model of your vehicle. In many vehicles you can find the reset button either under the steering wheel, inside the glove box, or within the media’s centre console.Why You Should Never Ignore the TPMS Warning Light. An underinflated tire–even minimally–can fail and endanger your safety. For example, underinflation causes tires to flex more, generating more heat. Under these conditions, other components inside the tire can overheat and break down.Check your vehicle’s owner’s manual and locate the TPMS light reset switch. Once you find it, turn your key to the On position, but don’t start the car. Press and hold the TPMS reset button until the warning light flashes three times, then release the switch.The TPMS light should turn off within several minutes after reinflating the tires to their recommended pressure.
Why is my tyre pressure light on when my tyres are fine?
If you’ve re-inflated your tyre to the correct air pressure and the warning alert is still on your dashboard, you may have a faulty sensor that needs replacing. This is worth mentioning to your mechanic when you next visit. In most cars, the tire pressure sensor is located within the tire attached to the valve stem or banded to the wheel. Indirect TPMS systems may not have physical sensors on the tires but use the vehicle’s ABS to monitor pressure.Hold the tpms reset button until the tire pressure light blinks three times, then release it. Start the car and wait 20 minutes for the sensor to refresh. The tire pressure monitor reset button is usually located beneath the steering wheel. If you can’t find it, check the user’s manual.Checking a vehicle’s tire pressure monitoring system (TPMS) is as easy as getting into the car and turning the ignition on. If the TPMS indicator light turns off, the system is functioning properly and you can be on your way. If it remains on or starts flashing, there may be an issue.Pull over as soon as you can and check your tire pressure. Some systems give a generic warning, while others give a specific pressure.
Why is my tire light still on after I pumped air into it?
If you have recently filled up your tires and the TPMS light remains illuminated, there are a few possible reasons: Sensor malfunction: One or more sensors in your TPMS system may be faulty, requiring professional inspection and repair. Sensor Malfunctions: If your tire pressure is within the recommended range, but the sensor triggers a warning light, it may be malfunctioning. Handling Differences: Should you notice handling changes like swerving or flat tires without a TPMS alert, the sensor might be failing to detect these crucial pressure drops.Replacing a tire pressure sensor (TPMS sensor) is a task that can be handled by most do-it-yourself enthusiasts with the right tools and safety precautions.This is why you should maintain proper inflation pressure and try to avoid driving when the TPMS light is on. If you absolutely must drive a short distance on a tire with severely low pressure, drive very slowly and use extreme caution. The tire should be inflated or changed before driving anywhere.The average tire sensor cost for a direct TPMS sensor can range between $70 and $150, while indirect systems may be slightly less expensive. Vehicle model – Luxury vehicles or newer models may require more sophisticated and costly sensors, increasing the total replacement cost.While it’s technically possible to drive a car with a bad TPMS sensor valve, it’s not advisable for several reasons. Firstly, as outlined above, doing so compromises your safety and that of other road users. Secondly, it can result in increased running costs due to reduced fuel efficiency and accelerated tyre wear.
Why won’t my tire pressure light go off after filling tires?
If your light stays on after you fill your tires, the system is probably having trouble detecting the correct levels. However, if you’re facing a flashing tire pressure light, you might be dealing with a broken sensor, or with a dying battery. If there has not been a significant change in the weather and your tire pressure light appears, it could mean an air leak or faulty battery in one of your sensors.After about 20 minutes of driving, the air will often warm up and expand, restoring proper pressure in your tires. If the light stays on after 20 minutes on the road, you should add air to your tires as needed to restore the proper pressure.If the light remains on after adjusting the tire to the proper PSI, you may need to repair your tire, have your TPMS inspected, or try one of the following: Go for a 10-minute drive. Get up to 50 MPH, if possible. Your vehicle may be equipped with a TPMS reset button or reset procedure in your vehicle control center.Key Reasons Why Your TPMS Light Is On This can happen due to normal air loss over time or a small leak. Temperature Changes: As the seasons change, so does the air pressure in your tires. Cold weather can cause your tire pressure to drop, while hot weather might increase it. Both scenarios can trigger your TPMS light.
