The most common reasons a 2013 Ford C-Max 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 2013 Ford C-Max 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 2013 Ford C-Max?

To effectively diagnose the tire pressure warning light issue on your 2013 Ford C-Max, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. Ensure that the readings align with the recommended PSI found in your owner's manual or on the sticker located on the driver's side door jamb. Next, inspect each tire for visible damage, such as punctures or bulges, and look for any foreign objects that may be lodged in the tread, as these can lead to air leaks. If you find any discrepancies in tire pressure, adjust it accordingly using an air compressor, ensuring that each tire is inflated to the correct level. After making these adjustments, it may be necessary to reset the Tire Pressure Monitoring System (TPMS) to clear the warning light; refer to your owner's manual for specific reset instructions. Additionally, don't overlook the spare tire, as a low-pressure spare can also trigger the warning light. If the light persists despite these efforts, it may indicate a more complex issue with the TPMS sensors, at which point consulting a certified mechanic or dealership for professional assistance is advisable. By following this diagnostic approach, you can systematically address the tire pressure warning light issue and ensure your vehicle's safety on the road.

What could be causing the tire pressure warning light to stay on in a 2013 Ford C-Max?

When the tire pressure warning light stays on in a 2013 Ford C-Max, it can be frustrating, but understanding the common problems can help you troubleshoot effectively. A faulty Tire Pressure Monitoring System (TPMS) sensor is often the main issue, as it may not accurately detect tire pressure, causing the light to remain illuminated. Even if your tire pressure seems fine, the TPMS might need a reset to clear the warning. Additionally, a malfunction within the TPMS system itself could be the culprit, which may require professional diagnosis and repair. By examining these potential issues, you can take the necessary steps to resolve the warning light concern, ensuring your vehicle's tire pressure monitoring system operates properly for optimal safety and performance.

What should I do if the tire pressure warning light on my 2013 Ford C-Max stays on?

When the tire pressure warning light on your 2013 Ford C-Max remains illuminated, it is crucial to act swiftly to avoid serious safety risks and potential damage to your vehicle. Ignoring this warning can lead to underinflated tires, which not only compromise your vehicle's handling and braking performance but also increase the likelihood of tire blowouts. Additionally, driving on improperly inflated tires can lead to uneven wear, resulting in costly replacements and repairs. Start by checking the tire pressure in all tires, including the spare, and ensure they are inflated to the manufacturer's recommended levels. If you find any tires are underinflated, inflate them immediately to maintain optimal performance. Furthermore, inspect your tires for any visible damage, as this could exacerbate the issue. After making necessary adjustments, resetting the tire pressure monitoring system is essential to clear the warning light. If the light persists, it may indicate a deeper issue with the monitoring system itself, necessitating professional evaluation. By addressing the tire pressure warning light promptly, you not only enhance your safety on the road but also protect your vehicle from potential long-term damage.
