The most common reasons a 2021 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 2021 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 on my 2021 Ford Transit Connect?

To effectively diagnose the tire pressure warning light issue on your 2021 Ford Transit Connect, begin with a thorough check of the tire pressure across 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, conduct a visual inspection of the tires for any signs of damage, such as punctures, cuts, or bulges, and look for any foreign objects that may be embedded in the tread, as these could lead to air leaks. If the tire pressure is correct and the tires appear to be in good condition, the next step is to reset the tire pressure monitoring system (TPMS), as it may require recalibration after adjustments. Refer to your owner's manual for specific instructions on how to perform this reset. However, if the warning light remains illuminated despite these checks, it may indicate a malfunctioning sensor or a deeper issue within the TPMS, at which point consulting a mechanic or dealership for professional diagnosis and repair is advisable. By following this systematic approach, you can efficiently identify and address the cause of the tire pressure warning light, ensuring your vehicle remains safe and roadworthy.

What could cause the tire pressure warning light to remain on in a 2021 Ford Transit Connect?

When the tire pressure warning light remains on in a 2021 Ford Transit Connect, it can signal several common issues that DIY enthusiasts should be prepared to troubleshoot. The most frequent cause is low tire pressure; checking and inflating your tires to the recommended levels is a simple yet crucial step that can often resolve the warning light. If the tire pressure is adequate, the problem may stem from a faulty tire pressure sensor, which might need replacement. Additionally, the sensors could require recalibration to ensure accurate readings, a task that can sometimes be accomplished at home with the right tools, though it may also necessitate professional assistance. Electrical faults within the tire pressure monitoring system can also trigger the warning light, and diagnosing these issues typically requires specialized equipment. Lastly, performing a system reset might be all that's needed to turn off the warning light, a process that can often be done by following the vehicle's manual instructions. Addressing these issues promptly not only enhances safety but also maintains the vehicle's performance, making it essential for any DIYer to stay informed about potential tire pressure monitoring system failures.

What should I do if the tire pressure warning light stays on in my 2021 Ford Transit Connect?

When the tire pressure warning light remains illuminated in your 2021 Ford Transit Connect, it is crucial to act swiftly to avoid safety hazards and potential damage to your vehicle. Ignoring this warning can lead to decreased fuel efficiency, compromised handling, and increased tire wear, which may ultimately result in costly repairs. Start by checking the tire pressure in all tires, including the spare, and ensure they are inflated to the recommended levels found in your owner's manual. If you discover any underinflated tires, inflate them accordingly, as driving on low-pressure tires can significantly affect your vehicle's performance and safety. Additionally, inspect each tire for visible damage, such as punctures or cuts, which could lead to a blowout if left unaddressed. After making necessary adjustments, resetting the tire pressure monitoring system is often required to clear the warning light. If the light persists despite your efforts, it is essential to consult a certified mechanic, as there may be underlying issues with the monitoring system that need professional attention. By taking these steps promptly, you can ensure your vehicle remains safe and reliable on the road.
