OE Style Design and Performance
Denso’s OE Style line is built to match original equipment requirements for fit, function, and serviceability. The sensor uses a precision-built design for direct replacement, and Denso’s aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination. That protection supports stable engine management, improved fuel economy, and longer service life in the exhaust stream. This Denso oxygen sensor is a direct choice for Lexus GS300 owners replacing a downstream sensor with the correct part number 234-4806.
This part cross-references Toyota 8946530710 for the same application.
What This Sensor Helps Address
- Check engine light related to downstream oxygen sensor faults
- Incorrect air-fuel ratio feedback after sensor aging
- Reduced fuel economy caused by slow or inaccurate sensor response
- Emissions test failures tied to oxygen sensor performance
- Rough running or drivability issues linked to exhaust sensor data
Installation Notes and Tips
Fits 2006 Lexus GS300, downstream. Fits 2006 Lexus GS300, downstream right. Confirm the connector style, wire count, and threaded mounting location before installation. Because this is a specific-fit sensor, match the original routing and harness length to avoid strain on the wiring. Use proper exhaust sensor service practices on the threaded mount to help prevent damage during removal and installation.
Quality Assurance
Denso manufactures and tests this sensor to OE standards for replacement accuracy and consistent performance. The OE Style design is intended to deliver the correct fit and function for the listed Lexus GS300 applications.
