The most common reasons a 2015 Ford Transit Connect 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 Transit Connect 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 Transit Connect?

To effectively diagnose the tire pressure warning light issue in your 2015 Ford Transit Connect, begin with a thorough check of the tire pressure in all four tires. Utilize a reliable tire pressure gauge to ensure that each tire is inflated to the recommended PSI, which can be found in your owner's manual or on the sticker located on the driver's side door jamb. Next, inspect the tires for any visible damage, such as punctures, cuts, or bulges, as these can lead to air loss and trigger the warning light. Additionally, examine the valve stems for any signs of damage or leaks, since faulty valve stems can also cause air to escape. If everything appears normal but the warning light remains illuminated, consider resetting the tire pressure monitoring system (TPMS) according to the instructions in your owner's manual. If the light persists after these steps, it may be necessary to consult a mechanic or dealership for a professional diagnosis, as there could be underlying issues that require expert attention. By following this diagnostic approach, you can systematically address the tire pressure warning light and ensure your vehicle's safety and performance.

What could cause the tire pressure warning light to remain on in a 2015 Ford Transit Connect?

When the tire pressure warning light remains on in a 2015 Ford Transit Connect, it is crucial to identify the underlying issues to ensure safe driving conditions. The most common culprit is low tire pressure, which can be easily resolved by checking and inflating the tires to the recommended levels. If the tire pressure is adequate, the problem may stem from a faulty tire pressure sensor that fails to provide accurate readings, necessitating recalibration to restore functionality. Additionally, electrical or wiring issues within the tire pressure monitoring system can trigger the warning light, making it essential to inspect connections for any damage or loose wires. In some cases, a malfunctioning control module may be responsible, which could require replacement or reprogramming. By addressing these potential problems promptly, you can enhance the safety and performance of your vehicle, making regular maintenance and proactive troubleshooting vital for keeping your Transit Connect in optimal condition.

What should I do if the tire pressure warning light on my 2015 Ford Transit Connect stays on?

When the tire pressure warning light on your 2015 Ford Transit Connect remains illuminated, it is crucial to take immediate action to avoid potential safety hazards and costly repairs. Ignoring this warning can lead to decreased vehicle performance, increased tire wear, and even tire blowouts, which pose serious risks while driving. Start by checking the tire pressure in all tires, including the spare, to ensure they are inflated to the recommended levels. If you find any tires underinflated, inflate them accordingly. Additionally, inspect the tires for any visible damage, such as punctures or leaks, as these can exacerbate the problem. If the warning light persists after addressing the tire pressure, it may indicate a malfunction in the tire pressure monitoring system, necessitating a reset or professional diagnosis. By promptly addressing the tire pressure warning light, you not only enhance your vehicle's safety and performance but also prevent further complications that could arise from neglecting this critical issue.
