How to Disable Chevy TPMS: What Is Legal and What Works
Search for how to disable the tire pressure monitoring system on a Chevy and you will find forum threads that treat the light as a nuisance. It is federal safety equipment. Under FMVSS No. 138, every passenger car, SUV, pickup and bus of 10,000 lb GVWR or less (excluding vehicles with dual wheels on an axle) built on or after September 1, 2007 must carry a working TPMS, so there is no factory off switch to find.
This guide covers what the light is actually telling you, the manufacturer procedures to clear it on a Silverado, Colorado, Malibu and Equinox (taken from the Chevrolet owner’s manuals, not from forum hearsay), why it stays on after a fix, and what disabling TPMS really costs you. Where I could not confirm something from a primary source, it is listed at the end.
Quick Answer
You cannot legitimately switch TPMS off on a modern Chevy, and you would not want to. What you can do is clear the cause of the light: set all four tires to the door-jamb pressure, and run the sensor matching (relearn) procedure if you rotated tires, swapped wheels or replaced a sensor. A light that flashes for about a minute and then stays on means a TPMS fault, and that needs a dealer or tire shop.
Can You Disable TPMS on a Chevy?
Best Pressure Check Pick

Not as a supported setting. FMVSS No. 138 requires the system to light a warning no more than 20 minutes after one or more tires (up to all four) fall to 25 percent below the vehicle maker’s recommended cold pressure, and to warn the driver of a system malfunction. A separate federal statute, 49 U.S.C. 30122, bars a manufacturer, distributor, dealer, rental company or motor vehicle repair business from knowingly making inoperative a device installed to meet a safety standard, unless it reasonably believes the vehicle will not be used while the device is disabled. A shop that sells you a TPMS “delete” is exposed to that. The statute’s text speaks to businesses, and your state may have its own inspection or equipment rules, so check them before you modify anything.
The practical argument is stronger than the legal one. Chevrolet’s own manuals say a significantly under-inflated tire overheats and can fail, and that the TPMS does not replace normal tire maintenance. With the system silenced, the first sign of a slow leak is how the truck handles.
What the Chevy TPMS Light Is Telling You
The behavior of the light is itself the diagnosis. These meanings come from the 2018 Silverado, 2019 Colorado, 2018 Malibu and 2019 Equinox owner’s manuals, which use the same wording on this topic.
| What you see | What it means | What to do |
|---|---|---|
| Low tire pressure light stays on, DIC message names a tire | One or more tires are significantly under-inflated | Stop as soon as possible and inflate to the Tire and Loading Information label |
| Light on at a cold start, then goes out as you drive | Cool air lowered pressure; an early warning that pressure is getting low | Check all tires cold and top up to the label |
| Light flashes for about one minute, then stays on, every ignition cycle | TPMS malfunction: a missing or damaged sensor, no matching after a rotation, a spare in use, or mismatched wheels | Work through the sections below; see a dealer if it persists |
How low is low? The 25 percent rule in numbers
The standard sets the latest point at which the light must be on: at or below 25 percent under the recommended cold pressure. Few owners see that arithmetic, and it explains why a tire can look fine and still trip the light.
| Door-jamb pressure | Light must be on at or below | Pressure loss |
|---|---|---|
| 32 psi | 24 psi | 8 psi |
| 35 psi | 26.3 psi | 8.8 psi |
| 38 psi | 28.5 psi | 9.5 psi |
| 40 psi | 30 psi | 10 psi |
| 45 psi | 33.8 psi | 11.3 psi |
These are the standard’s limits, not the exact trigger on your truck. A maker may set the threshold higher, and the standard also sets a minimum pressure that can override the 25 percent figure on some tires. Use the label on the driver’s door opening, not the maximum pressure molded into the sidewall.
How to Disable the Chevy TPMS Light: Clear the Cause, Then Relearn
“Disabling” the light really means clearing the condition that set it. The order below follows the owner’s manuals.
- Park on level ground and check every road tire cold with a gauge. Inflate to the Tire and Loading Information label. The manuals say the light and DIC message return each ignition cycle until the tires are at the correct pressure.
- If you rotated the tires, replaced a sensor, or put a road tire back after using the spare, run the TPMS sensor matching process below. The manuals state the malfunction light and message should go out at the next ignition cycle after a successful match.
- If the light flashes then stays on after a correct match, a sensor is likely missing or damaged: take it to a dealer or a tire shop with a TPMS tool.
TPMS sensor matching process, step by step
Each sensor has a unique identification code that must be matched to its wheel position. All four manuals call for a TPMS relearn (sensor activation) tool, available through a dealer or GM tools and equipment. You have two minutes to match the first wheel and five minutes for all four, or the process stops and must be restarted. How you start learn mode depends on the vehicle:
| Vehicle (manual year read) | Before you start | How to enter learn mode |
|---|---|---|
| 2018 Silverado | Set the parking brake, turn the ignition on without starting the engine | Uplevel DIC: scroll to the Tire Pressure screen and press and hold V (Set/Reset). Base DIC: scroll to Tire Pressure with the trip odometer reset stem, hold it about five seconds, then confirm yes |
| 2019 Colorado | Set the parking brake, turn the ignition on without starting the vehicle | Uplevel DIC: hold V on the Tire Pressure screen. Base DIC: MENU, Vehicle Information, Tire Pressure, then press SET/CLR on the turn signal lever and confirm with SET/CLR again |
| 2018 Malibu and 2019 Equinox | Set the parking brake, place the vehicle in Service Mode, turn the Tire Pressure info page on in the DIC Options menu | Scroll to the Tire Pressure screen with the right-hand DIC controls and press and hold V |
After that the sequence is the same on all four, per the manuals. The horn sounds twice and TIRE LEARNING ACTIVE shows on the DIC. Start at the driver front tire, hold the tool against the sidewall near the valve stem and press its button; a horn chirp confirms the match. Repeat at the passenger front, passenger rear and driver rear. Two horn sounds at the last wheel end the process. Turn the vehicle off and set all four tires to the recommended pressure.
Traverse and older trucks are not covered here because I did not read those manuals, and the procedure differs by model year, so use the manual for your vehicle’s year. You will notice there is no “reset button” step: the TPMS sections of the four manuals I read describe the DIC relearn above instead. The Silverado manual also says sensors are mounted on each tire and wheel assembly excluding the spare, so a spare is not monitored there.
Why the TPMS Light Stays On After You Fix the Pressure
The manuals list the same causes of a TPMS malfunction light and message:
| Cause (per owner’s manual) | What clears it |
|---|---|
| A road tire was swapped for the spare, which has no sensor | Put the road tire back, then run the matching process |
| Tires were rotated and the matching process was never completed | Complete the sensor matching process |
| One or more sensors are missing or damaged | Install sensors and match them; see a dealer |
| Replacement tires or wheels do not match the originals | Use recommended tires and wheels; non-TPC-spec tires can also cause inaccurate warnings |
| Nearby radio-frequency devices or facilities | Move away and recheck |
| A non-approved tire sealant damaged the sensors | Sensor replacement; the manual says this damage is not covered by the warranty |
One practical consequence of the last row: use only GM-approved sealant. The manual also says to replace TPMS sensors with new GM original equipment parts.
Winter Wheels, Aftermarket Wheels and TPMS Bypass Tools
The most common real reason people search for how to disable TPMS is a second set of wheels with no sensors in them. The manual’s guidance is to check the TPMS malfunction light after replacing tires or wheels, because alternate wheels can stop the system working. The clean fix is a sensor in every wheel, installed and matched to the vehicle, which keeps a working low-pressure warning on the winter set.
What about bypass emulators, sensor removal, or reprogramming the module? Neither the owner’s manuals nor the federal standard describe any of them, so there are no steps here. What they share is the outcome the manual describes for a malfunction: the system may not be able to detect or signal low pressure as intended. On a vehicle driven on public roads you are trading a warning you rely on for a dark dash, and a shop doing it takes on the legal exposure described above.
When to Stop Driving or Call a Professional
- Light on and a tire looks low, bulged or damaged: stop as soon as it is safe and inspect the tire, as the manual directs. Do not keep driving on a significantly under-inflated tire.
- Flashing then solid after a correct relearn: the system cannot warn you about low pressure, so have it diagnosed at a dealer.
- Sensor damage after using sealant or a recent tire change: a tire shop or dealer should replace and match the sensors.
For related troubleshooting, see our guide to resetting the service side detection system on a Chevy Traverse, or if you drive a Ford, our explainer on turning off Ford’s TPMS. The full text of the standard is on the Electronic Code of Federal Regulations (49 CFR 571.138).
Frequently Asked Questions
Is disabling TPMS on a Chevy illegal?
FMVSS No. 138 requires TPMS on light vehicles built on or after September 1, 2007, and 49 U.S.C. 30122 prohibits manufacturers, dealers, rental companies and repair businesses from knowingly making a required safety device inoperative unless they reasonably believe the vehicle will not be used. Resetting the light after correcting pressure is the intended use of the system. Check your state rules before modifying anything.
Where is the TPMS reset button on a Chevy?
The Silverado, Colorado, Malibu and Equinox manuals I read describe no reset button. They start the sensor matching process from the Driver Information Center, using the V (Set/Reset) control, the trip odometer reset stem or SET/CLR depending on the vehicle, and a TPMS relearn tool.
How do I turn off the TPMS light on a Chevy?
Set all tires to the pressure on the Tire and Loading Information label. If you rotated tires, replaced a sensor or used the spare, run the sensor matching process. The light should go out at the next ignition cycle after a successful match.
Why does my Chevy TPMS light flash and then stay on?
That is the malfunction pattern: the light flashes for about one minute and then stays on. Causes include a missing or damaged sensor, a spare tire in use, unmatched sensors after a rotation, or tires and wheels that do not match the originals.
Does the Chevy TPMS monitor the spare tire?
In the Silverado manual I read, sensors are mounted on each tire and wheel assembly excluding the spare tire and wheel assembly. Check your own manual, because equipment varies by vehicle.
What I Could Not Verify
- Whether your state treats an owner-installed TPMS bypass as an inspection or equipment violation (not researched).
- Procedures for the Traverse and for Chevrolet vehicles older than the manuals read; check the manual for your model year.
- The exact warning threshold your truck uses; the 25 percent figure is the federal limit, not a measured value for any one vehicle.
