GM Buick Park Avenue Tire Pressure Sensor TPMS 15268606

When the Buick LaCrosse instrument cluster frequently shows “Check TPMS” warnings or all four tire pressures display abnormal or no signal, the stock tire pressure sensors may be aging or battery-depleted, failing to monitor tire pressure properly. The sensor should send real-time per-tire pressure and temperature data to the vehicle system to identify leaks or abnormal pressures and prevent blowouts. This product fits Buick LaCrosse; OEM number 15268606. Confirm year and system compatibility. Professional technician installation recommended; after replacement, re-learn sensor IDs with a dedicated tool and ensure valve stem seals are intact to prevent leaks.
