The most common reasons a 2018 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 2018 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 2018 Ford Transit Connect?

To effectively diagnose the tire pressure warning light issue on your 2018 Ford Transit Connect, begin with the simplest solution: checking the tire pressure in all tires, including the spare. Use a reliable tire pressure gauge to ensure each tire is inflated to the recommended levels found in your owner's manual. If the pressure is low, inflate the tires accordingly. Next, visually inspect each tire for any signs of damage, such as punctures or bulges, which could trigger the warning light. If the tires appear to be in good condition and the pressure is correct, proceed to reset the tire pressure monitoring system, as outlined in your manual, to see if that resolves the issue. Should the warning light remain illuminated, it may indicate a malfunctioning tire pressure sensor, necessitating further investigation. If you are unable to identify or fix the problem after these steps, it is advisable to consult a mechanic or a Ford dealership for professional assistance, as they possess the necessary tools and expertise to accurately diagnose and repair the issue. By following this diagnostic approach, you can systematically address the tire pressure warning light concern and ensure your vehicle's safety and performance.

What could cause the tire pressure warning light to stay on in a 2018 Ford Transit Connect?

When the tire pressure warning light remains illuminated in your 2018 Ford Transit Connect, it can be frustrating, but understanding the common problems can help you diagnose the issue. One of the primary culprits is low tire pressure, which is easily checked with a tire pressure gauge. Ensure all tires are inflated to the manufacturer's recommended levels, as even a slight drop can trigger the warning light. If the pressure is adequate, consider the possibility of a faulty tire pressure sensor; these sensors can wear out over time and may need replacement. Additionally, sensor calibration issues can arise, particularly if tires have been recently changed or rotated, necessitating a recalibration to ensure accurate readings. Electrical faults within the tire pressure monitoring system can also cause the light to stay on, which may require professional diagnostic testing to pinpoint the problem. Lastly, check for any electronic interference or physical obstructions near the sensors, as these can disrupt the system's functionality. By systematically addressing these potential issues, you can effectively troubleshoot and resolve the persistent tire pressure warning light in your vehicle.

How urgent is it to address the tire pressure warning light on a 2018 Ford Transit Connect that stays on?

Addressing the tire pressure warning light on a 2018 Ford Transit Connect is not just a matter of convenience; it is a critical safety concern that requires immediate attention. When this warning light remains illuminated, it indicates that one or more tires may be underinflated, which can severely compromise the vehicle's handling and braking capabilities. This situation increases the likelihood of accidents, particularly in emergency scenarios where quick response is essential. Additionally, driving on underinflated tires accelerates uneven wear, leading to premature tire replacement, which can be a costly expense for any vehicle owner. Furthermore, low tire pressure negatively impacts fuel efficiency, resulting in higher fuel costs over time. Perhaps most alarmingly, continued operation with insufficient tire pressure can lead to tire damage or even blowouts, posing a significant risk to both the driver and other road users. Therefore, it is crucial to check and adjust tire pressure according to the manufacturer's specifications as soon as the warning light activates, or to consult a professional if you are unsure how to proceed. Taking these steps not only ensures your safety but also protects your vehicle from unnecessary damage and expense.
