The most common reasons a 2015 Ford Taurus tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2015 Ford Taurus tire pressure warning light stays on?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When a tire pressure monitoring sensor fails, the tire pressure monitoring system control module will recognize a loss in communication and turn on the warning lamp which indicates the failure. This is most often the case. However, the tire pressure monitoring sensor may also fail by reporting incorrect tire pressures. This could cause a flat tire to go unrecognized, or a properly inflated tire to signal a low or high tire pressure warning.

When a relearn is needed, for any reason, the TPMS warning light will illuminate, and many vehicles will display a message relating to the TPMS system being inoperative or loosing communication. It is important to keep a watchful eye on tire pressures when this system is having issues because there is no warning available for underinflation or overinflation of the tires.

Wheels offer very few symptoms, but these symptoms should never be ignored. Visible cracks on the wheels may appear, especially after hitting a large bump, Most often, this will also be accompanied by loss of air from the tire on that wheel. Also, vibration in the steering wheel is very common when the tire is out of balance, and improper wheel nuts or bolts can cause creaking and popping noises to develop. Again, there are very few symptoms, but they should not be ignored.

The only symptoms requiring diagnosis for the tire pressure monitoring system warning lamp is if the warning lamp has illuminated while the tires have correct air pressure, or if the air pressure for the tires is out of specification and the warning lamp is off. This is because the overwhelming majority of cases where the TPMS lamp illuminates is due to the change in ambient temperature.

What steps should I take to diagnose the tire pressure warning light issue in my 2015 Ford Taurus?

When diagnosing the tire pressure warning light issue in your 2015 Ford Taurus, it's essential to adopt a systematic approach that begins with the simplest solutions. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring they are inflated to the levels recommended in your vehicle's manual. This initial step can often resolve the warning light if the pressure is low. Next, inspect each tire for visible damage, such as punctures or bulges, which could also trigger the warning. If the tires appear to be in good condition and properly inflated, consider resetting the tire pressure monitoring system (TPMS) as outlined in your vehicle's manual, as it may simply need recalibration. Don’t overlook the spare tire; checking its pressure is crucial since a low spare can also activate the warning light. If, after these steps, the warning light remains illuminated, it may be time to consult a mechanic for a more comprehensive diagnosis, as there could be underlying issues with the TPMS or other components. By following this diagnostic approach, you can effectively troubleshoot the tire pressure warning light and ensure your vehicle remains safe and roadworthy.

What could be causing the tire pressure warning light to remain on in a 2015 Ford Taurus?

When the tire pressure warning light stays on in your 2015 Ford Taurus, it can be frustrating, but understanding the common problems can help you troubleshoot effectively. Start by checking the tire pressure in all four tires, as low pressure is the most frequent cause of the warning light. If the pressure is within the recommended range, the issue might be a faulty tire pressure sensor, which may need replacement. Another possibility is that the tire pressure monitoring system requires recalibration to ensure it functions correctly. It's also important to inspect your tires for any leaks or damage, as even a small puncture can lead to a drop in pressure that triggers the warning light. Lastly, consider the condition of the wiring and control module associated with the tire pressure sensors, as electrical issues can also cause the light to remain illuminated. By addressing these potential problems, you can resolve the tire pressure warning light issue and ensure your vehicle is safe to drive.

How urgent is it to address the tire pressure warning light on a 2015 Ford Taurus that stays on?

When the tire pressure warning light on a 2015 Ford Taurus remains illuminated, it signals an urgent need for attention to ensure both safety and vehicle performance. Ignoring this warning can lead to serious consequences, such as compromised handling, increased braking distances, and diminished fuel efficiency due to under-inflated tires. A leaking tire or a malfunctioning tire pressure monitoring system could be the culprits, and driving on tires that are not properly inflated increases the risk of tire blowouts, which can result in dangerous situations on the road. Therefore, it is essential to check the tire pressure using a reliable gauge and inflate the tires to the manufacturer's recommended levels as soon as possible. If the light persists despite correct tire pressure, it may indicate a faulty TPMS sensor that requires resetting or replacement. By promptly addressing the tire pressure warning light, you not only enhance your safety but also prolong the life of your tires and improve overall vehicle efficiency.
