4Piece Tire Pressure Sensor DE8T1A180AA 315MHz for TPMS12 Key benefits Restores tire pressure monitoring: Replaces failed or aging sensors to clear TPMS warnings and restore accurate tire pressure reporting. Direct compatibility: Designed for vehicles using the TPMS12 protocol and operates at 315MHz. Part number DE8T1A180AA provides a direct replacement option for compatible systems. Complete kit for all wheels: Four sensors included so you can all sensors at once for consistent performance and simplified maintenance. Practical and reliable design: Compact OEstyle sensor housing and sealed electronics help ensure consistent signal transmission and longterm operation. What this sensor does Monitors tire pressure and transmits sensor data to the vehicle TPMS receiver at 315MHz. Replaces existing TPMS sensors that match part number DE8T1A180AA and TPMS12 protocol to restore correct system readings. Compatibility and fit Compatible with select vehicles that use the TPMS12 protocol operating at 315MHz. Confirm vehicle TPMS specification and part number DE8T1A180AA before . Designed as a directfit replacement for systems requiring the specified part number and frequency. Installation and service notes Sensors typically install at the valve stem inside each wheel. Professional tire service is recommended for safe removal and installation of tires and sensors. Vehicle relearn or programming may be required after installation to register sensor IDs with the vehicle TPMS receiver. Follow vehicle manufacturer procedures or consult a qualified technician. Typical applications all four sensors after TPMS warning light appears due to sensor failure or end of sensor life. Install when fitting a set of wheels or tires to ensure the TPMS continues to report accurate pressure for each wheel. Swap sensors when changing between seasonal tire sets or moving sensors between OEM and aftermarket wheels. Technical highlights Quantity: 4 sensors Part number: DE8T1A180AA Frequency: 315MHz Protocol: TPMS12 Why choose this 4piece kit Replacing all four sensors at once avoids mixed sensor ages and batteries, helping maintain uniform system readings. Clear, compatible replacement for vehicles using TPMS12 at 315MHz and the specified part number, enabling straightforward restoration of TPMS function. Before you Verify that your vehicle uses the TPMS12 protocol at 315MHz and that part number DE8T1A180AA is appropriate for your application. Plan for a relearn or programming step after installation to ensure the vehicle recognizes the sensors.
