The most common reasons a 2015 Ford Transit-350 HD 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-350 HD 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 are the initial steps to diagnose the tire pressure warning light issue on a 2015 Ford Transit-350 HD?

When diagnosing the tire pressure warning light issue on a 2015 Ford Transit-350 HD, it's essential to adopt a systematic diagnostic approach that prioritizes simpler solutions before delving into more complex issues. Begin by checking the tire pressure of all four tires with a reliable gauge, ensuring that each tire is inflated to the recommended levels found in the vehicle's manual. A visual inspection of the tires is also crucial; look for any visible damage such as punctures, cuts, or bulges, and check for any foreign objects lodged in the tread that could affect performance. If the tire pressure appears correct and the tires are in good condition, the next step is to reset the tire pressure monitoring system (TPMS), as sometimes the system may require a reset to clear any false warnings. Additionally, inspect the TPMS sensors on each tire to confirm they are functioning properly, as faulty sensors can trigger the warning light. If the light remains illuminated after these checks, it may be time to consult a professional mechanic for a comprehensive diagnosis of the TPMS system. By following this structured approach, you can effectively troubleshoot the issue and ensure your vehicle's safety on the road.

What could be causing the tire pressure warning light to remain on in a 2015 Ford Transit-350 HD?

When the tire pressure warning light stays on in a 2015 Ford Transit-350 HD, it often indicates several common issues that can be addressed through DIY troubleshooting. The first step is to check the tire pressure in all tires, as low pressure is a frequent cause of the warning light. Ensuring that each tire is inflated to the recommended levels can often resolve the issue quickly. If the tire pressure is adequate, the next area to investigate is the tire pressure monitoring system (TPMS) sensors. These sensors can fail or have depleted batteries, leading to inaccurate readings. Replacing faulty sensors or their batteries is a manageable task for DIYers. Additionally, the TPMS may need recalibration to function correctly, which can usually be done following the vehicle's manual instructions. Lastly, inspect the electrical connections and wiring associated with the TPMS, as any faults here can also trigger the warning light. By methodically checking these components, you can effectively diagnose and potentially fix the tire pressure warning light issue on your own.

What immediate steps should be taken if the tire pressure warning light remains on in a 2015 Ford Transit-350 HD?

When the tire pressure warning light remains illuminated in your 2015 Ford Transit-350 HD, it is crucial to act promptly to ensure your safety and the vehicle's performance. Ignoring this warning can lead to unsafe driving conditions, increased tire wear, and potential blowouts. Start by checking the tire pressure in all tires, including the spare, using a reliable tire pressure gauge. If you find any tires are underinflated, inflate them to the recommended levels as specified in your vehicle's manual. This simple step can often resolve the warning light issue. Next, inspect each tire for visible damage such as punctures or bulges, as these can compromise tire integrity and safety. If you have adjusted the tire pressure and the light remains on, consult your vehicle's manual for instructions on resetting the tire pressure monitoring system. However, if the warning persists, it is essential to seek professional assistance to diagnose any underlying problems with the monitoring system. Addressing these issues promptly not only enhances your safety on the road but also helps prevent more significant and costly repairs down the line.
