Chevrolet Buick XTS Tire Pressure Sensor 23445327 Accurate Matching Tire Pressure

When your Chevrolet Buick XTS dashboard shows tire pressure warning lamp on continuously or tire pressure values display abnormally (e.g., one tire never updates, shows “--”, or deviation from actual pressure is large), this usually indicates a dead battery or aging/failed internal module of the original tire pressure sensor; replace promptly. This sensor monitors tire pressure and temperature in real time and transmits data wirelessly to the vehicle receiver to ensure accurate dashboard display of each tire’s status, preventing blowouts or increased fuel consumption due to abnormal tire pressure. OEM number 23445327; precisely fits Chevrolet Buick XTS (2013–2019). Installation notes: be sure to use special tools to remove tires and replace sensors; after installation, perform tire pressure learning/matching (some models require a diagnostic tool or manual reset); also check valve stem seal for leaks.
