The most common reasons a 2019 Ram ProMaster 3500 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 2019 Ram ProMaster 3500 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.

What are the initial steps to diagnose a persistent tire pressure warning light on a 2019 Ram ProMaster 3500?

When faced with a persistent tire pressure warning light on your 2019 Ram ProMaster 3500, it's essential to adopt a systematic diagnostic approach. Begin by checking the tire pressure in all tires, including the spare, ensuring they are inflated to the recommended levels outlined in your owner's manual. Low pressure is often the primary culprit behind the warning light. Next, inspect each tire for visible damage such as punctures or bulges, which could lead to air loss. If the tires appear fine, attempt to reset the tire pressure monitoring system as per the manufacturer's instructions, as this can sometimes resolve false alerts. To ensure accuracy, use a reliable tire pressure gauge to confirm the readings. Finally, if the warning light persists after these checks, consult your owner's manual for further troubleshooting guidance, as it may provide insights into more complex issues that require professional attention. By following this methodical approach, you can effectively diagnose and address the tire pressure warning light on your vehicle.

What could be causing the tire pressure warning light to stay on in a 2019 Ram ProMaster 3500?

When the tire pressure warning light stays on in a 2019 Ram ProMaster 3500, it can signal various underlying issues that DIY enthusiasts can address. The most common reason is low tire pressure, which can be easily checked and adjusted using a tire pressure gauge. If the pressure is adequate but the light remains illuminated, a faulty tire pressure sensor may be at fault, necessitating its replacement. Additionally, some sensors rely on batteries that can wear out over time, so checking and replacing these batteries might resolve the issue. It's also worth considering potential interference from electronic devices or other sensors, which can disrupt the tire pressure monitoring system; relocating these devices could help. Lastly, if the system is not calibrated correctly, recalibrating it according to the manufacturer's instructions can often reset the warning light. If these steps do not resolve the issue, seeking assistance from a qualified mechanic is recommended to identify any deeper problems.

How urgent is it to address the tire pressure warning light on a 2019 Ram ProMaster 3500?

Addressing the tire pressure warning light on a 2019 Ram ProMaster 3500 is an urgent matter that should not be overlooked. Ignoring this warning can lead to serious safety concerns, as improper tire pressure significantly affects vehicle handling, braking, and stability, increasing the risk of accidents. Additionally, neglecting to check tire pressure can result in uneven tire wear, which not only shortens the lifespan of your tires but also diminishes fuel efficiency, leading to higher operating costs. The risk of tire damage, including blowouts or flats, escalates when driving on under-inflated tires, posing both safety hazards and potential repair expenses. Furthermore, maintaining the correct tire pressure is vital for optimal vehicle performance, ensuring better traction, steering response, and overall driving comfort. Therefore, it is crucial to take immediate action when the tire pressure warning light illuminates, safeguarding both your safety and the longevity of your vehicle.
