DENSO 234-5746 Air/Fuel Ratio Sensor OE-Identical Replacement

The DENSO 234-5746 is an OE-identical air/fuel ratio (AFR) sensor engineered to deliver factory-precise exhaust gas monitoring for compatible vehicles. As a wideband oxygen sensor, it continuously measures the air-to-fuel mixture across a broad range—approximately 12:1 to 19:1—supplying the engine control unit (ECU) with the exact data needed to optimize combustion, maximize fuel efficiency, and minimize harmful emissions.

Key Features:

• OE-Identical Design: Manufactured by DENSO, a leading original equipment supplier to major automakers, ensuring exact fit, form, and function to factory specifications
• Quick-Response Planar Zirconia Element: Accurately detects oxygen concentration for fast, precise air/fuel ratio feedback to the ECU
• Aluminum-Oxide Trap Layer: Protects the ceramic sensing element from silicone and lead contamination, extending service life and maintaining long-term accuracy
• Tarnish-Proof Platinum Electrode: Provides superior durability and sustained measurement accuracy over the sensor's lifespan
• Double Protection Cover: Maintains optimal sensor operating temperature for quicker response and shields the ceramic element from contamination
• Stainless Steel Housing: Corrosion-resistant construction with a rugged, watertight body for reliable performance in harsh exhaust environments
• First Time Fit: Precision-built for direct, no-modification installation

DENSO Air/Fuel Ratio Sensors are manufactured and tested to strict OE standards, helping restore peak engine performance, reduce fuel consumption, and extend catalytic converter life. The 234-5746 is the trusted choice for a reliable, like-new replacement.
