TPMS Warning Light
Chevrolet Vehicle
Severity: ModerateWhat Does This Error Mean?
The Chevrolet TPMS warning light means one or more tires are significantly below the recommended pressure. Check all four tires with a gauge and inflate to the pressure on the door jamb sticker. The light resets automatically after a few minutes of driving once pressures are corrected.
Affected Models
- Chevrolet Silverado
- Chevrolet Equinox
- Chevrolet Malibu
- Chevrolet Traverse
- Chevrolet Colorado
- Chevrolet Blazer
- Chevrolet Tahoe
- Chevrolet Suburban
Common Causes
- Tire pressure 25 percent or more below the recommended level
- Cold weather causing air to contract and reduce tire pressure
- Slow puncture or nail in the tread
- Dead TPMS sensor battery — typical life is 5-10 years
- TPMS sensor damaged during a tire change or rotation
- Incorrect tire size fitted after replacement
How to Fix It
-
Check all four tire pressures with a digital gauge.
Do this when tires are cold — driven less than 1 mile — for an accurate reading. Do not use the pressure number on the tire sidewall. Use the sticker inside the driver door jamb.
-
Inflate any low tires to the recommended PSI.
Most Chevrolet cars run 32-35 PSI. Silverado and Tahoe trucks often run 35-38 PSI front and rear. The correct pressure is always on the door jamb sticker.
-
Drive above 25 mph for 5-10 minutes to allow the TPMS system to reset.
Chevrolet TPMS resets automatically when it reads correct pressures at speed. There is no manual reset button on most Chevy models.

If the light flashes for 60-90 seconds at startup and then stays solid, a sensor fault is likely.
A solid light after inflation = pressure was low. A flashing-then-solid light = sensor fault. Sensor batteries typically last 5-10 years. If your Chevy is older and sensors have never been replaced, a dead battery is likely.
The Chevrolet TPMS (Tire Pressure Monitoring System) warning light is a federal safety requirement on all US vehicles since 2008. Small radio transmitters inside each wheel broadcast tire pressure to the vehicle’s body control module. When any tire drops 25 percent or more below the recommended level, the warning light illuminates on the dashboard.
Understanding the Light Patterns
The TPMS warning light on Chevrolet vehicles has two distinct behaviours. A solid light means one or more tires are low on pressure — check and inflate them. A light that flashes for approximately 60-90 seconds after startup and then stays on solid means there is a sensor malfunction — the system cannot read one or more sensors and the issue requires diagnosis.
Cold Weather and Seasonal Pressure Loss
One of the most common reasons Chevrolet owners suddenly see the TPMS light is cold weather. Tires inflate correctly in warm weather will drop in pressure as temperatures fall — roughly 1 PSI for every 10 degrees Fahrenheit of temperature drop. A tire at 33 PSI in summer can drop to 29-30 PSI on a cold winter morning, enough to trigger the warning. Topping up the tires solves this immediately.
After a Tire Rotation or Replacement
TPMS sensors are programmed with the position of each wheel. After a tire rotation, some Chevrolet models require the TPMS sensors to be relearned so the display shows which specific tire is low. Your dealer or tire shop can perform this relearn procedure in under ten minutes using a TPMS activation tool.
Frequently Asked Questions
Why does my Chevy TPMS light come on in cold weather?
For every 10 degrees Fahrenheit the temperature drops, tire pressure falls by approximately 1 PSI. A tire correctly inflated in summer may trigger the TPMS warning during the first cold snap of winter. Simply inflate to the correct pressure and the light goes out.
How do I reset the TPMS light on a Chevrolet?
On most Chevrolet models there is no manual reset button. After correcting tire pressures, drive above 25 mph for several minutes and the system resets automatically. If it does not reset after correct inflation and 15 minutes of driving, a sensor fault is likely.
Can I drive with the Chevrolet TPMS light on?
You can drive short distances at reduced speed to reach a garage. Do not drive at highway speeds with a low tire — an underinflated tire generates excess heat and can fail suddenly.
