If you're hunting around your cabin for the 2020 ram 1500 tpms reset button location, you can stop reaching under the dashboard or digging through the glovebox right now. Here's the short version: there isn't a physical button to press. I know, it sounds a bit annoying when you just want that glowing orange horseshoe light to disappear from your dash, but modern Rams handle things a bit differently than the trucks we grew up with.
Most older vehicles had a tiny, recessed button somewhere near the steering column that you'd have to hold down until a light flashed. On the 2020 Ram 1500, Chrysler (now Stellantis) decided to go with an "Auto-Learn" system. This means the truck is designed to figure out the tire pressure situation on its own once you've fixed the actual problem. However, knowing that doesn't always make the light go away immediately, so let's talk about how to actually get that system to reset and what to do if it's being stubborn.
Why you can't find a physical button
It's actually pretty common for folks to spend ten minutes with a flashlight looking for a reset switch. We've been conditioned to think every warning light needs a "clear" button. But in the 2020 Ram 1500, the Tire Pressure Monitoring System (TPMS) is fully integrated into the truck's computer and the instrument cluster display.
The engineers basically decided that if the sensors are working and the air pressure is correct, the light should just turn off. If it's still on, the truck thinks there's still an issue. It's a bit of a "tough love" approach to vehicle maintenance. You don't have to menu-dive to find a "reset" command because the reset happens automatically through driving.
How to trigger the auto-reset
Since there's no button to push, you have to follow a specific sequence to get the computer to realize you've added air. If you've just filled up your tires at a gas station and the light is still staring you in the face, don't panic. It doesn't always update the second the air hits the valve stem.
First, make sure all your tires are inflated to the recommended PSI. Don't guess this number. Check the sticker inside the driver's side door jamb. It'll give you the exact "Cold Tire Pressure" for your specific trim and tire setup.
Once the pressures are right, here's what you do: 1. Turn the ignition to the 'On' or 'Run' position (but you don't necessarily have to start the engine yet, though it helps). 2. Use the arrows on your steering wheel to scroll through the menu on your digital dash. 3. Find the "Vehicle Info" section and scroll over until you see the tire pressure screen. 4. If the numbers look correct but the light is still on, you need to drive. 5. Drive the truck for about 10 to 20 minutes at a steady speed of at least 15 mph.
Usually, within a few miles of consistent driving, the sensors "wake up," talk to the central module, and realize the pressure is back to normal. The light should wink out on its own.
What if the light stays on?
If you've driven down the highway for half an hour and that light is still mocking you, there's usually a reason for it. Since we've established there is no 2020 ram 1500 tpms reset button location to force it off, we have to look at other culprits.
The Spare Tire Factor One thing that trips up a lot of Ram owners is the spare tire. Depending on your specific package, your full-size spare might actually have a TPMS sensor in it. If that spare is tucked up under the bed and has leaked air over the last year, the truck might be picking up that low signal even though your four main tires are perfect. It's always worth checking the pressure in the spare if you're hitting a wall with the reset process.
Cold Weather Blues We see this every year when the first cold snap hits. Physics kicks in, and the air inside your tires becomes denser, dropping your PSI just enough to trigger the sensor. If your light came on during a cold morning, it might go off once the tires warm up from driving. However, it's usually better to just add a few pounds of air to meet the door jamb specs.
Dealing with faulty sensors
Sometimes, the reason the light won't reset is that a sensor has simply given up the ghost. The 2020 Ram 1500 uses battery-powered sensors inside the wheels. While 2020 is still relatively recent, sensors can fail early due to road salt, vibration, or just a dud battery from the factory.
If your dash screen shows a "dashed line" (-- ) or an "N/A" for one specific tire instead of a pressure reading, that's a dead giveaway that the sensor isn't communicating. In this case, no amount of driving or looking for a reset button will help. You'll need to have the sensor replaced. Any decent tire shop can scan the sensors with a handheld tool to tell you exactly which one isn't "talking" to the truck.
Aftermarket wheels and TPMS
Did you recently put new wheels or beefier tires on your Ram? This is where things get tricky. If the shop didn't swap your old sensors into the new wheels, or if they didn't install the correct 433 MHz sensors that the 2020 Ram 1500 requires, your light is going to stay on forever.
Some cheap aftermarket sensors don't play nice with the Ram's Auto-Learn system. If you're in this boat, you might actually need a specialized TPMS programming tool to "marry" the new sensors to the truck's computer. Again, it's not a button-pushing job inside the cab; it's an external fix.
A quick summary of the "Reset" steps
Since we've covered a lot of ground, let's boil it down to a simple checklist for when you're standing in your driveway frustrated:
- Check the door sticker: Find the PSI (usually around 35-39 PSI for a standard 1500).
- Inflate while cold: Try to fill them before you've driven a long distance.
- Check all four: Don't just eyeball them; use a digital gauge.
- Don't forget the spare: It might be the silent culprit.
- Drive it: 15-20 minutes at 20+ mph.
- Watch the dash: Use the steering wheel buttons to monitor the "Vehicle Info" screen.
Wrapping it up
It can be a little annoying that there isn't a simple 2020 ram 1500 tpms reset button location to make life easier. It feels like we've lost a bit of control over our machines when we have to wait for a computer to "decide" the tires are okay. But the Auto-Learn system is actually pretty robust once you understand it needs movement and correct pressure to do its job.
If you've done the air check, done the drive, and checked the spare, and that light is still glowing, it's time to stop by a tire shop. Most places will scan your sensors for free or a very small fee. It's much better than staring at an orange warning light for the next six months. Just remember: in the 2020 Ram, you are the reset button—or rather, your driving is. Get those pressures right, hit the road, and the truck should take care of the rest.
