Match the connector shape, wire count, and thread size to the original sensor, and confirm fitment against the application tab for your specific Lexus ES350, Toyota Camry, or Toyota Avalon.

For best results, inspect the harness routing and exhaust threads before installation. Use the included instruction sheet during replacement and ensure the sensor is installed in the correct bank and position for the vehicle.
