The most common reasons a 2017 Ford Focus 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 2017 Ford Focus 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 on my 2017 Ford Focus?

To effectively diagnose the tire pressure warning light issue on your 2017 Ford Focus, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. Ensure that each tire is inflated to the recommended levels outlined in your vehicle's manual, as improper inflation is a common cause of warning lights. Next, inspect the tires for any visible damage, such as punctures, cuts, or bulges, which could indicate a more serious problem. If the tire pressure and condition appear normal, consider resetting the tire pressure monitoring system (TPMS), as it may require recalibration after adjustments. Refer to your vehicle's manual for specific instructions on how to perform this reset. Additionally, examine the TPMS sensors on each tire to confirm they are functioning correctly and free from damage. If, after completing these steps, the warning light remains illuminated, it is advisable to consult a mechanic or dealership for a professional diagnosis and repair of the TPMS system. By following this diagnostic approach, you can systematically address the issue and ensure your vehicle's safety on the road.

What could be causing the tire pressure warning light to stay on in a 2017 Ford Focus?

When the tire pressure warning light stays on in a 2017 Ford Focus, it can be a source of concern for any DIY enthusiast. The first step in troubleshooting this issue is to check the tire pressure in all four tires, as low pressure is the most common reason for the warning light to illuminate. Make sure each tire is inflated to the recommended levels, which can typically be found on a sticker located inside the driver's door. If the tire pressure is adequate, the next possibility is a faulty tire pressure sensor, which may need replacement if it is malfunctioning. Additionally, if the sensors have been recently serviced, they might require recalibration to ensure accurate readings. It's also wise to inspect the vehicle's electrical system for any issues, such as damaged wiring or blown fuses, as these can also trigger the warning light. If all these checks are performed and the light remains on, the tire pressure monitoring system itself may be experiencing a malfunction, which would require a more thorough diagnosis. Addressing these potential issues is essential for maintaining the safety and performance of your vehicle, and if the problem persists, consulting a professional mechanic is advisable.

How urgent is it to address the tire pressure warning light that stays on in a 2017 Ford Focus?

Addressing the tire pressure warning light in a 2017 Ford Focus is not just a matter of convenience; it is a critical safety issue that demands immediate attention. When this warning light remains illuminated, it signals that one or more tires may be underinflated, which can severely compromise vehicle handling and braking performance. This poses a heightened risk of accidents, particularly in emergency situations where quick response is essential. Furthermore, driving on underinflated tires accelerates uneven wear, leading to premature tire replacement, which can be costly. Additionally, low tire pressure negatively impacts fuel efficiency, resulting in increased fuel expenses over time. The risk of tire damage, including potential blowouts, is another serious concern that can arise from ignoring this warning. Therefore, it is crucial to check and inflate the tires to the recommended levels promptly, and if the warning light persists, seeking professional assistance is advisable to prevent further complications and ensure safe driving conditions.
