What Will You Need?
Before we delve into the signs of a bad tire sensor, let’s ensure you have all the necessary tools and equipment. These include:
- Tire pressure gauge
- Air compressor (if needed)
- Jack and Jack stands
- Flashlight or headlamp
- Basic knowledge of your vehicle’s tire sensor system
With these items in place, you can efficiently perform the necessary checks to determine if your tire sensors are functioning correctly.
10 Easy Steps on How to Know if Tire Sensor is Bad
Step 1. Check the Dashboard Warning Light
The first step in determining if your tire sensor is bad is to examine your vehicle’s dashboard for any warning lights. Most vehicles equipped with tire pressure monitoring systems (TPMS) will have a specific light that illuminates when there’s an issue with one or more of the tire sensors.
If this light is on, it may indicate low tire pressure, a sensor malfunction, or a flat tire. Be sure to check your owner’s manual for specific details regarding the warning lights related to tire sensors.
Step 2. Inspect Tire Pressure Readings
Once you’ve checked the dashboard warning light, it’s time to examine the tire pressure readings from your sensors. Using a tire pressure gauge, manually measure the pressure in each tire.
Compare these readings to the recommended pressure in your vehicle’s owner’s manual or the sticker typically found on the driver’s side door jamb. If you notice that one or more tires have significantly lower pressure than the others, this could point to a leak or a potential issue with the tire sensor itself.
Inconsistent readings between the displayed values from the tire sensors and your manual measurements can also indicate a faulty sensor. For example, if the sensor shows a typical reading while the manual gauge indicates low pressure, the sensor might not accurately detect the tire’s true pressure.
Pay particular attention to any tires that read pressure levels far from the recommended range, as this might suggest a failed or malfunctioning sensor that warrants further investigation or replacement.
Step 3. Look for Physical Damage to the Sensors
After checking the dashboard and tire pressure readings, physically inspect the tire sensors themselves. Most tire sensors are mounted to the valve stem of each tire and should be closely examined for any visible signs of damage, such as cracks, corrosion, or loose connections.
If you notice any abnormalities, it may indicate that the sensor needs to be replaced. Additionally, ensure that the valve stem is not bent or damaged, which can also affect sensor performance.
Step 4. Monitor for Unusual Tire Wear
Another essential sign of a faulty tire sensor is irregular tire wear patterns. If one or more tires exhibit unusual wear, it may suggest that the tire pressure needs to be adequately monitored and adjusted.
Take a close look at the tread depth and surface of each tire. Uneven wear could point to over-inflation or under-inflation due to malfunctioning sensors. Addressing these irregularities early on can save you from more significant issues.
Step 5. Test the Sensors with a Scan Tool
If you can access an OBD-II scan tool, you can read codes related to the tire pressure monitoring system (TPMS). This tool can help identify if any stored fault codes may suggest a malfunctioning tire sensor.
By reviewing the data from the scan tool, you can gain further insight into the specific issues affecting your tire sensors and decide on an appropriate course of action.
Step 6. Evaluate Sensor Battery Life
Tire sensors often have batteries that power their operation, typically lasting about five to ten years. If your vehicle’s tire sensors are older, evaluating the battery life is wise. A weak or dying battery can lead to inaccurate readings or complete sensor failure.
To check the battery, consult your vehicle’s manual for guidance on the location of the sensor battery and whether it is user-serviceable or requires professional assistance to replace it.
Step 7. Review Recent Changes to Tire Setup
If you’ve recently changed your tires or had them serviced, it’s essential to consider whether these changes might have impacted the tire sensors. New tires may come with different sensors, or previous service may have damaged existing sensors during installation.
If the problem appeared shortly after a tire change, retracing your steps to check for oversight during installation could reveal the issue. Double-check that all sensors are correctly paired with the vehicle and haven’t been inadvertently damaged.
Step 8. Check for Interference from External Sources
In some cases, electromagnetic interference from other devices may disrupt the regular operation of tire sensors. Check if any nearby devices or changes in your environment may interfere with the tire pressure monitoring system.
This is particularly relevant for vehicles with advanced infotainment systems or aftermarket modifications. If you suspect interference, temporarily turning off or relocating the devices can help determine if that resolves the sensor issues.
Step 9. Seek Professional Diagnosis
If you’ve followed the previous steps and are still trying to figure out the condition of your tire sensors, it might be time to seek a professional diagnosis. A qualified mechanic can thoroughly inspect the tire pressure monitoring system, using advanced diagnostic equipment to pinpoint issues with the sensors.
This step can save you time and money by ensuring that any repairs or replacements address the correct problem without unnecessary guesswork.
Step 10. Regular Maintenance and Checks
To prevent future issues with your tire sensors, you must incorporate regular maintenance and checks into your vehicle care routine. Make it a habit to inspect your tires and their sensors periodically, especially before long trips or when changing seasons.
Regularly checking the tire pressure and ensuring that your sensors function correctly can enhance safety and performance, reducing the likelihood of being caught off guard by a malfunctioning sensor.
Keeping your tires in good shape contributes to a smoother ride and extends the lifespan of your tire sensors. By following these steps and staying vigilant about your tire sensors, you can ensure that they continue to function correctly and keep you safe on the road.
5 Things You Should Avoid
- Relying Solely on Visual Inspections: While checking for physical damage is important, avoid relying only on visual inspections. Tire sensors can malfunction without any visible signs, so additional diagnostic tools should be employed for accurate assessment.
- Assuming New Sensors Are Always Accurate: Do not assume that newly installed sensors are functioning correctly. Always verify their performance after installations or changes to your tire setup, as improper installation can lead to issues.
- Delaying Professional Help: If problems with your tire sensors persist, avoid prolonging seeking professional assistance. Early intervention can prevent more extensive damage and ensure your safety on the road.
- Don’t Use Generic Scan Tools: A generic OBD-II scan tool may not provide accurate or detailed information about your tire sensors. For accurate readings and diagnosis, it is best to use a specialized TPMS diagnostic tool.
- Skip Noticing Changes in Performance: Neglecting changes in performance, such as handling or braking issues, could indicate that your tire sensors are malfunctioning. Be aware of any unusual changes and address them promptly to prevent further damage.
By following these simple tips, you can ensure that your tire sensors stay in top condition and provide accurate readings, contributing to a safer and smoother driving experience.
