Getting a 2020 chevy equinox tire pressure sensor reset handled shouldn't feel like a major weekend project, but that little orange light on your dashboard can definitely be a nuisance. Whether you just filled your tires because the temperature dropped or you've just finished rotating them in your driveway, seeing that "Low Tire Pressure" warning stay on is enough to make anyone a bit crazy. Most of the time, the system is just doing its job, but it occasionally needs a little nudge to realize everything is back to normal.
Why is that light still on?
Before you start clicking through your dashboard menus, it's worth thinking about why the light is there in the first place. On a 2020 Equinox, the Tire Pressure Monitoring System (TPMS) is pretty sensitive. It's designed to alert you if any of your tires drop below a certain threshold—usually around 25% under the recommended PSI.
If you just added air and the light is still staring at you, don't panic. Sometimes the car just needs to move. These sensors often don't send a fresh "all clear" signal to the car's computer until the wheels are actually spinning at a decent clip. Usually, driving over 20 mph for about 10 or 15 minutes is enough for the system to update itself. But if you've driven to work and back and that light is still glowing, it's time to look at the manual reset or relearn process.
The difference between a reset and a relearn
There's a bit of a terminology mix-up that happens a lot with these cars. A simple "reset" often happens automatically once you fill the tires to the correct pressure (check that sticker on your driver's side door jamb—don't just guess!).
A "relearn," on the other hand, is what you need when you've moved the tires around. Since each sensor has a unique ID, your Equinox needs to know that the sensor that used to be on the front-left is now on the back-right. If you don't do the 2020 chevy equinox tire pressure sensor reset procedure after a rotation, your car might tell you the front tire is low when it's actually the rear one. That's a recipe for confusion later on.
Preparing for the reset
First things first: you've got to make sure your tire pressures are actually correct. It sounds obvious, but you'd be surprised how many people try to reset the system while a tire is still five pounds low. Grab a reliable gauge—those old pencil-style ones are okay, but a digital one is usually a bit more accurate for modern TPMS systems.
Find your recommended cold tire pressure. Again, this is on the sticker inside the driver's door, not the "max pressure" listed on the tire sidewall itself. For a 2020 Equinox, it's usually around 35 PSI, but double-check your specific trim. Once they're all filled up, you're ready to dive into the settings.
How to do the relearn (The DIY way)
To actually perform the 2020 chevy equinox tire pressure sensor reset for the sensor positions, you'll generally need a small TPMS relearn tool. You can find these online for about twenty bucks, and honestly, if you do your own rotations, it's the best money you'll ever spend on your Chevy.
- Park the car and turn the ignition to the "On" position (but don't start the engine). For push-button starts, hold the Start button down for about five seconds without your foot on the brake.
- Use the controls on your steering wheel to navigate the Driver Information Center (DIC). You're looking for the Tire Pressure screen.
- Once you're on the tire pressure display, press and hold the "Checkmark" or "Set/Reset" button on your steering wheel.
- The car should honk twice. This is the Equinox's way of saying, "Okay, I'm listening." You'll also notice the front-left turn signal will light up.
- Go to the front-left tire. Hold your relearn tool against the tire sidewall near the valve stem and press the button. The car will honk once to confirm it read that sensor.
- The turn signal will then move clockwise around the car (Front-Right, then Rear-Right, then Rear-Left). Repeat the process at each tire.
- After the last tire, the horn will honk twice again to signify the process is complete. Turn the car off to save the settings.
What if you don't have the tool?
A lot of older GM vehicles allowed you to do this by letting air out of the tires until the car honked, but Chevy moved away from that for the 2020 models to prevent people from accidentally draining their tires in a parking lot.
If you don't want to buy the tool, your best bet is to swing by a local tire shop. Most of the time, if you're a regular customer or if they're just feeling nice, they'll walk out with their professional scanner and do the 2020 chevy equinox tire pressure sensor reset for you in about thirty seconds. It's way faster than trying to trick the system.
Dealing with "Service Tire Monitor System"
If your dashboard says "Service Tire Monitor System" instead of just "Low Tire Pressure," you're dealing with a different beast. This usually means the car has lost contact with one or more sensors entirely.
Since the 2020 Equinox isn't that old, it's a bit early for a sensor battery to die (they usually last 5 to 10 years), but it's not impossible. Extreme heat or cold can sometimes finish off a weak battery. If you try the reset process and the car refuses to honk at one specific tire, that sensor is likely dead or damaged. Road debris or a particularly nasty pothole can sometimes crack the sensor inside the wheel.
Cold weather and "Ghost" lights
We've all been there: it's the first truly cold morning of October, and your dashboard is lit up like a Christmas tree. Air contracts when it gets cold. For every 10-degree drop in temperature, you can lose about 1 PSI.
If your tires were already on the edge of being low, a cold snap will trigger that light. In this case, you don't usually need a full 2020 chevy equinox tire pressure sensor reset. Just fill the tires back up to the door placard specs, drive for a few miles, and the car should realize the pressure is back where it belongs. If it stays on after a long drive, then you can start looking into the manual reset steps.
A quick note on the spare tire
One thing that trips up Equinox owners is the spare tire. Does it have a sensor? In most cases, no. If you're running on your "donut" spare, the car is going to complain. It'll show a blank reading or a dashed line for that wheel position. You won't be able to "reset" this away because there's no sensor in that spare wheel for the car to talk to. You'll just have to live with the light until you get your full-sized tire repaired and back on the vehicle.
Keeping things running smoothly
To avoid having to mess with a 2020 chevy equinox tire pressure sensor reset constantly, try to make tire checks a monthly habit. It's much easier to add two pounds of air in your driveway than it is to deal with a warning light while you're running late for work. Plus, keeping your tires at the right pressure helps your Equinox get better gas mileage and prevents your tires from wearing out unevenly.
If you find that you're constantly resetting the system and the light keeps coming back every few days, you probably have a slow leak. A small nail in the tread can cause a tire to lose just enough air to trigger the TPMS every 72 hours. It's worth getting it checked out before a slow leak turns into a flat tire on the highway.
Anyway, don't let the technology frustrate you. Once you know the sequence, managing the TPMS on your Equinox is pretty straightforward. Whether you use the tool or just let the car recalibrate itself on the road, it's all about making sure those four patches of rubber are safe and ready for the drive.
