4-Wire Heated Oxygen Sensor

The Denso 234-4733 is a direct-fit oxygen sensor engineered to meet or exceed OE specifications for your vehicle's air-fuel mixture monitoring needs. Its construction utilizes a robust zirconia material and features an aluminum-oxide trap layer to shield the platinum electrode from silicone and lead poisoning. A double protection cover ensures proper operational temperature for quicker response times, while the stainless steel housing provides resistance against corrosion and contamination. This heated, 4-wire sensor comes with a 13.19-inch wiring harness and an OE-type connector for a seamless installation. The porous PTFE filter allows atmospheric oxygen to enter while preventing water and contaminants from entering the sensor's casing. It is designed with a threaded mounting type for secure placement. Denso oxygen sensors are manufactured and tested to strict OE standards, ensuring the quality and performance expected from a direct-fit component.
