The most common reasons a Ram ProMaster 2500 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 Ram ProMaster 2500 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 of a TPMS control module failure are failing to alert the driver of underinflation or overinflation of one or more tires, failure to communicate with the body control module or TPMS sensors, or erroneously reporting incorrect tire pressure.

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.

Troubleshooting Tire Pressure Warning Light in a Ram ProMaster 2500

When faced with a persistent tire pressure warning light in your Ram ProMaster 2500, start by inspecting each tire for visible signs of damage or leaks. A simple visual check can often reveal punctures or foreign objects embedded in the tire that may be causing air loss. If the tires appear intact, proceed to check the air pressure using a reliable gauge, ensuring that each tire is inflated to the manufacturer's recommended levels. If you find that one or more tires are under-inflated, inflate them accordingly and monitor if the warning light resets itself after a short drive. If the light remains on despite proper inflation, the issue may lie within the tire pressure monitoring system (TPMS) itself. In this case, consider consulting your vehicle's manual for instructions on how to reset the TPMS, as this can sometimes resolve the issue. However, if the light persists after these steps, it may indicate a malfunctioning sensor, necessitating a visit to a professional for further diagnosis and potential replacement. Regularly maintaining your tires and addressing pressure issues promptly not only enhances your vehicle's performance but also ensures your safety on the road.

Troubleshooting Tire Pressure Warning Light in Ram ProMaster 2500

When troubleshooting the tire pressure warning light in your Ram ProMaster 2500, it's crucial to understand the common problems that could be causing the alert. One of the primary issues is a leaking tire, which can lead to a gradual loss of air pressure, triggering the warning light. Inspecting your tires for visible punctures or damage is a good first step. Additionally, if a wheel is unable to hold air, it may also cause the light to remain illuminated; checking for any signs of corrosion or damage around the rim can help identify this issue. Another potential culprit is a malfunctioning tire pressure monitoring system (TPMS), which may require a diagnostic tool to assess. If you suspect that the TPMS is faulty, replacing the tire pressure sensor may be necessary. Remember, there is no reset button for the system; it will automatically clear itself once the underlying issue is resolved. If the warning light persists after addressing these common problems, it may be wise to consult a professional to ensure there are no deeper issues affecting your vehicle's safety and performance.

Why is the Tire Pressure Warning Light Staying On in a Ram ProMaster 2500?

When the Tire Pressure Warning Light remains illuminated in your Ram ProMaster 2500, it is crucial to address the issue without delay. Ignoring this warning can lead to unsafe driving conditions, as under-inflated tires can significantly affect vehicle handling, increase tire wear, and even lead to tire blowouts. Additionally, a malfunctioning tire pressure monitoring system (TPMS) can prevent you from receiving accurate alerts about your tire health, putting you at risk for more severe problems down the line. If you notice the light on, start by checking the tire pressures and ensuring they are within the recommended range. If the light persists after correcting the pressure, it may indicate a deeper issue, such as a faulty sensor or a need to reset the TPMS. Taking these steps not only enhances your safety on the road but also helps maintain the longevity of your tires and vehicle.
