The most common reasons a 2020 Ram 1500 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 2020 Ram 1500 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 2020 Ram 1500?

To effectively diagnose the tire pressure warning light issue on your 2020 Ram 1500, begin with a thorough assessment of your tire pressure. Utilize a reliable tire pressure gauge to check each tire, ensuring that the readings align with the recommended PSI found in your owner's manual or on the driver's side door jamb sticker. If the pressure is low, inflate the tires accordingly. Next, conduct a visual inspection of the tires for any signs of damage, such as punctures, cuts, or bulges, which could indicate a leak. Don’t overlook the valve stems; inspect them for any cracks or leaks that might be contributing to the problem. If everything appears normal but the warning light remains illuminated, consider resetting the tire pressure monitoring system (TPMS) as outlined in your owner's manual. This step can often resolve minor glitches. However, if the light persists despite these efforts, it may be time to consult a professional mechanic for a more in-depth diagnosis and repair. By following this structured approach, you can efficiently identify and address the underlying issues related to your tire pressure warning light.

What could cause the tire pressure warning light to stay on in a 2020 Ram 1500?

When the tire pressure warning light stays illuminated in a 2020 Ram 1500, it is essential to identify the underlying issues to ensure safe driving. The most common reason for this warning light is low tire pressure, which can occur due to slow leaks, temperature changes, or improper inflation. Regularly checking and maintaining the correct tire pressure is vital for optimal vehicle performance. Another possibility is a malfunctioning tire pressure sensor; if the sensor is defective, it may not provide accurate readings, causing the warning light to remain on. Additionally, the sensor's battery could be dead, preventing it from sending data to the vehicle's system. Electrical problems, such as faulty wiring or blown fuses, can also interfere with the tire pressure monitoring system, leading to a persistent warning light. Lastly, if you've recently had tire rotations or replacements, a calibration error may require resetting the system to clear the warning. By addressing these common issues, you can enhance your vehicle's safety and performance on the road.

How urgent is it to address the tire pressure warning light on a 2020 Ram 1500?

Addressing the tire pressure warning light on a 2020 Ram 1500 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 fuel costs over time. Furthermore, driving with low tire pressure heightens the risk of tire damage, including blowouts or flats, which can be both dangerous and expensive to repair. To maintain optimal vehicle performance, including traction and steering response, it is essential to promptly check and adjust your tire pressure. Taking these steps not only ensures your safety but also enhances the longevity of your tires and improves overall driving comfort. Therefore, if the tire pressure warning light illuminates, it is crucial to act quickly to avoid potential hazards on the road.
