If you're hunting for the 2019 ram 1500 tpms reset button location, I've got some news that might be a little bit of a letdown: there isn't actually a physical button to push. I know, it sounds counterintuitive. Most of us grew up with cars where you'd just dive under the dashboard, find a tiny plastic button, hold it for five seconds, and—voila—the annoying light goes away. But with the 5th generation Ram (and even the 2019 Classic models), the engineers decided to make things "smarter," which usually just means they hid the process inside a computer menu or made it automatic.
It's a common source of frustration for truck owners. You spend ten minutes filling your tires at a gas station in the freezing cold, hop back in the cab, and that glowing yellow horseshoe icon is still staring you in the face. You start poking around the steering wheel, looking in the glovebox, and checking by your left knee for a reset switch, but it simply isn't there.
Here is the deal: the 2019 Ram 1500 uses an auto-learn system. This means the truck is constantly talking to the sensors inside your wheels, and it's designed to figure out the pressure changes on its own. However, getting it to realize you've actually fixed the problem requires a specific sequence of events rather than just a button press.
Why isn't there a physical button?
Most modern vehicles have moved away from physical TPMS (Tire Pressure Monitoring System) reset buttons because they use "active" systems. In older cars, you often had to tell the car, "Hey, I fixed it, now check again." In your 2019 Ram, the sensors are battery-powered radio transmitters inside the tire. They send a signal to the truck's computer every few minutes while you're driving.
Since the truck is always listening for these signals, Chrysler (now Stellantis) figured a button was redundant. If the pressure is right, the truck should theoretically just know. Of course, as anyone who has owned a truck knows, theory and reality don't always hang out together. Sometimes the system gets stubborn and needs a little nudge to refresh.
How to trigger the reset without a button
Since you can't just click a switch, you have to follow the "drive to reset" method. This is the official way to clear that light once you've confirmed your tires are at the right PSI.
- Check your door jamb: First, don't guess the pressure. Open your driver-side door and look at the sticker on the B-pillar. It'll tell you exactly what your cold tire pressure should be. For a 2019 Ram 1500, it's often around 33-36 PSI, but it can vary depending on your specific trim and tire setup.
- Inflate accurately: Fill all four tires to that exact number. Even being a couple of pounds off can sometimes keep the light triggered, especially if one tire is significantly lower than the others.
- The "Drive Cycle": This is the crucial part. To get the computer to re-scan the sensors, you usually need to drive the truck for about 10 to 20 minutes at speeds above 15 mph.
- Be patient: Don't just drive around the block. The system needs a consistent signal. Usually, a quick trip down the highway or a steady cruise on a main road will do the trick. Once the computer receives a few consistent "healthy" pings from the wheel sensors, the light will turn off on its own.
Checking your pressure on the dashboard
Even though there isn't a reset button, you can still monitor what the truck is thinking. Whether you have the smaller 3.5-inch display or the big 7-inch driver information digital cluster, you can see individual tire pressures.
Use the arrow buttons on the left side of your steering wheel to scroll through the menu. You're looking for the Vehicle Info tab. Once you find that, scroll sideways until you see the tire pressure graphic. This screen is great because it'll show you exactly which tire the truck thinks is low. If you've filled all the tires but the screen still shows one in red, you know that specific sensor is the one being a pain.
What if the light stays on?
If you've driven for twenty minutes and that light is still mocking you, something else might be going on. Since the 2019 model year is now several years old, we're starting to see a few common "real world" issues pop up with these trucks.
The cold weather factor
Tire pressure drops about 1 PSI for every 10-degree drop in temperature. If you live somewhere where it gets chilly, you might wake up to a TPMS light every single morning in October. If the light goes off after you've been driving for a while (and the air inside the tires warms up), your pressure is just right on the edge of the threshold. I'd suggest adding 2-3 extra PSI (staying within the max limits) to give yourself a buffer for those cold snaps.
Failing sensor batteries
This is a big one. The TPMS sensors in your wheels have tiny lithium batteries built into them. They aren't replaceable; when the battery dies, you have to replace the whole sensor. Most of these batteries last 5 to 10 years. Since your Ram is a 2019, those sensors are reaching that middle-age point. If one sensor has a weak battery, it might stop sending signals intermittently, which keeps the light on even if the air pressure is perfect.
The spare tire mystery
People often forget about the spare. On some versions of the 2019 Ram, the spare tire actually has a sensor too. If you've checked all four main tires and they're perfect, but the light won't quit, crawl under the back of the truck and check the pressure in the spare. It's a "hidden" culprit that catches a lot of people off guard.
Dealing with aftermarket wheels
If you recently bought your 2019 Ram used, or if you just threw some beefy off-road tires and aftermarket rims on it, that might be why you're looking for a 2019 ram 1500 tpms reset button location.
A lot of aftermarket wheels don't come with sensors, or they use "universal" sensors that need to be programmed with a special tool at a tire shop. If the previous owner took the sensors out or if you bought wheels without them, the truck will never find a signal to "reset." In that case, no amount of driving will turn that light off. You'll either have to live with the light or head to a shop to have new sensors installed and synced to the truck's ECU.
A quick note on the "Classic" vs. "New" 2019 Ram
2019 was a weird year for Ram because they sold two completely different body styles at the same time. You had the "All-New" Ram 1500 (the DT model) and the "Ram Classic" (the DS model).
The good news is that for the purposes of the TPMS reset, they both behave pretty much the same. Neither has a physical button. Both rely on the auto-learn feature. The only real difference is how the menus look on your dashboard. The "New" Ram has a much more high-tech interface, but the "Vehicle Info" screen is still your home base for checking tire status.
Wrapping it up
It can be annoying that modern trucks don't just give us a simple button to clear dashboard alerts. But the logic behind the 2019 Ram 1500's system is that it's supposed to be "set it and forget it."
If you're staring at that light right now, just remember: inflate, drive, and wait. Ensure your pressures match the door sticker, take a 15-minute drive on a clear road, and the truck's computer should handle the rest. If it doesn't, it's probably time to stop looking for a button and start looking for a nail in the tread or a dying sensor battery.
Hopefully, this saves you from spending another hour digging through your glovebox or searching under your dash for a button that doesn't exist! Happy driving, and stay safe out there on the road.
