The most common reasons a 2020 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 2020 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 a tire pressure warning light that stays on in a 2020 Ford Transit-150?

To effectively diagnose a tire pressure warning light that remains illuminated in your 2020 Ford Transit-150, start by checking the tire pressure in all four tires, ensuring they are inflated to the manufacturer's recommended levels. Low tire pressure is a frequent culprit for this warning light. Next, inspect each tire for any visible damage, such as punctures or bulges, as these can lead to air loss and trigger the warning. If the tires appear to be in good condition, attempt to reset the tire pressure monitoring system as outlined in your vehicle's manual; this can sometimes resolve the issue. Additionally, examine the tire pressure sensors for proper functionality, as faulty sensors may inaccurately signal low pressure. If, after these steps, the warning light persists, it may be time to seek assistance from a professional mechanic who can conduct a more thorough diagnosis. By following this methodical approach, you can efficiently identify and address the cause of the tire pressure warning light in your Ford Transit-150.

What are the common causes for the tire pressure warning light to remain on in a 2020 Ford Transit-150?

When the tire pressure warning light remains on in a 2020 Ford Transit-150, it can be attributed to several common problems that DIYers can investigate. First and foremost, low tire pressure is often the culprit, which can occur due to natural air loss, temperature fluctuations, or slow leaks. Checking the tire pressure with a reliable gauge is a straightforward first step. If the pressure is adequate, the issue may lie with a faulty tire pressure sensor, which could be malfunctioning and providing inaccurate readings. In such cases, inspecting the sensor for damage or wear is advisable. Additionally, the sensor batteries may need replacement, as they can deplete over time, leading to persistent warning lights. Calibration issues can also arise, necessitating a reset of the TPMS to ensure accurate readings. Furthermore, electrical or wiring problems can disrupt communication between the sensors and the vehicle's system, so examining the wiring for any signs of damage is essential. Lastly, if all else fails, a malfunction within the TPMS system itself may be at play, which could require professional diagnosis. By systematically checking these potential issues, DIY enthusiasts can effectively address the tire pressure warning light concern in their Ford Transit-150.

How urgent is it to address the tire pressure warning light on a 2020 Ford Transit-150 that stays on?

Addressing the tire pressure warning light on a 2020 Ford Transit-150 that remains illuminated is of utmost urgency due to several critical factors. First and foremost, proper tire pressure is essential for safe driving; low tire pressure can severely compromise vehicle handling, braking, and stability, significantly increasing the risk of accidents. Additionally, driving on underinflated tires can lead to uneven wear, shortening their lifespan and heightening the risk of a blowout, which can be dangerous. Furthermore, neglecting this warning can negatively impact fuel efficiency, leading to higher fuel costs over time as underinflated tires require more energy to roll. Lastly, an ongoing warning light may indicate a malfunction in the Tire Pressure Monitoring System (TPMS), which could hinder its ability to accurately detect future tire pressure issues. Therefore, it is crucial to take immediate action when the tire pressure warning light is on to ensure safety, maintain tire integrity, and optimize vehicle performance.
