Oxygen Sensor Air Fuel Ratio 234-9154 for Toyota Highlander Camry Sienna

Oxygen Sensor Air Fuel Ratio 234-9154 from IWOKPHD is a heated upstream oxygen sensor designed to keep your Toyota and Lexus running at peak efficiency. This versatile sensor covers models like Highlander, Camry, Sienna, ES350, NX300h, RX350, RAV4, Avalon, Venza and more, making it a reliable direct replacement when your original sensor begins to fail.

Engineered for quick warm-up and precise signaling, this piezoelectric oxygen sensor helps the engine manage the air–fuel mixture more accurately. By restoring the correct ratio, it supports smoother idling, improved throttle response, consistent performance, and better fuel economy while reducing exhaust emissions. A proper upstream sensor is essential for optimal catalyst operation and clean, efficient combustion.
