Product Details
Denso OE Style oxygen sensors are manufactured and tested to OE standards, with attention to fit, signal accuracy, and durability. Part number 234-4433 uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management and long service life. This part cross-references Bosch 15334 for the same application.
Compatible With 2006-2008 Hyundai Sonata, upstream; 2006-2009 Kia Optima, upstream; 2007-2008 Kia Rondo, upstream; and 2007-2009 Kia Magentis, upstream. If you are replacing an upstream oxygen sensor on a Hyundai Sonata or Kia Optima, Denso 234-4433 is built for the specified OE-style fitment.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel mixture readings
- Reduced fuel economy from a failing upstream sensor
- Slow or inaccurate exhaust feedback to the engine control system
- Driveability issues caused by contaminated or worn sensor elements
Installation Notes
Verify the connector style, wire count, thread diameter, and upstream position before installation. Match the vehicle application exactly, since this is a specific-fit sensor and not a universal part. Inspect the exhaust bung threads and wiring routing during replacement to ensure proper sensor seating and harness placement.
Quality Assurance
Denso manufactures this oxygen sensor to OE standards and tests it for replacement fit and performance consistency. The OE Style line is designed to deliver the correct part and fit for the listed Hyundai and Kia applications.
