The most common reasons a 2015 Ford Transit-150 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-150 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 on a 2015 Ford Transit-150?

To effectively diagnose the tire pressure warning light on your 2015 Ford Transit-150, begin with a thorough check of the tire pressure across all four tires using a reliable tire pressure gauge. Ensure that the readings align with the recommended levels found in your owner's manual, as incorrect pressure is a common trigger for the warning light. Next, conduct a visual inspection of each tire, looking for any visible damage such as cuts, punctures, or bulges that could indicate a problem. If everything appears normal, consider resetting the tire pressure monitoring system (TPMS) as sometimes the light can be activated by a temporary glitch. Don’t overlook the spare tire, as it is also monitored by the TPMS and should be checked for proper inflation. If the warning light remains illuminated after these steps, it may be time to consult a professional mechanic for a more in-depth diagnosis, as there could be underlying issues that require expert attention. By following this methodical approach, you can efficiently troubleshoot the tire pressure warning light and ensure your vehicle is safe and roadworthy.

What are the common causes for the tire pressure warning light to remain on in a 2015 Ford Transit-150?

When the tire pressure warning light remains illuminated in a 2015 Ford Transit-150, it often indicates underlying issues that require attention. The most prevalent cause is low tire pressure, which can easily be checked and corrected by inflating the tires to the manufacturer's recommended levels. However, if the pressure is adequate, the problem may lie with a faulty tire pressure sensor, which could necessitate replacement to restore proper functionality. Additionally, low or dead batteries in the tire pressure sensors can trigger the warning light, making battery replacement a potential solution. In some cases, the tire pressure monitoring system may need recalibration to ensure accurate readings, especially after tire changes or rotations. It's also crucial to inspect the wiring and connections associated with the system, as any damage or loose connections can lead to persistent warning lights. Lastly, environmental factors such as extreme temperature changes can affect tire pressure readings, so regular monitoring is advisable to avoid false alerts. By systematically addressing these common issues, you can effectively troubleshoot and resolve the tire pressure warning light concern in your vehicle.

How urgent is it to address the tire pressure warning light on a 2015 Ford Transit-150 that stays on?

Addressing the tire pressure warning light on a 2015 Ford Transit-150 is crucial for maintaining both safety and vehicle performance. When this light remains illuminated, it signals that one or more tires may be underinflated, which can severely compromise handling and braking capabilities, increasing the likelihood of accidents. Additionally, driving on underinflated tires accelerates uneven wear, leading to premature tire replacement, which can be costly. Furthermore, low tire pressure negatively impacts fuel efficiency, resulting in higher fuel expenses over time. Ignoring this warning can also lead to significant tire damage, including the risk of a blowout while driving. Therefore, it is essential to check and adjust tire pressure according to the manufacturer's specifications as soon as the warning light activates. If the light persists after adjustments, it may indicate a deeper issue that warrants professional evaluation. Taking these steps not only ensures your safety but also protects your investment in the vehicle.
