If the tire pressure warning light on your Chevrolet Silverado or GMC Sierra stays on even after you've properly inflated your tires, the problem likely isn't the air — it's the sensor itself. TPMS sensors are battery-powered devices mounted inside each wheel, and like any battery-powered part, they eventually wear out.
1. Light Stays On After Inflating Tires
If you've checked and corrected tire pressure but the warning light persists, one or more sensors may be malfunctioning or reporting inaccurate readings.
2. Intermittent or Random Warnings
A sensor nearing the end of its battery life (typically 7-10 years) often triggers warnings inconsistently before failing completely.
3. Warning Light After Tire Service
TPMS sensors can be damaged during tire changes or rotations if not handled carefully. If the light appeared right after a tire shop visit, a sensor may have been knocked loose or damaged.
4. No Signal from One or More Wheels
Some vehicles will display which specific tire is having an issue, or show a generic warning if the module can't read one sensor at all — a clear sign that sensor needs replacement.
5. Why Genuine ACDelco Sensors Matter
Aftermarket TPMS sensors can struggle with signal consistency or fail to communicate properly with GM's onboard module. Genuine ACDelco/GM sensors (like the 13540601) are engineered specifically to communicate with your vehicle's factory TPMS module without programming issues.
A Simple Fix
Replacing all four sensors at once — rather than one at a time — ensures consistent signal strength and battery life across the set, and avoids repeat trips to the shop.
