Denso OE Style Oxygen Sensor 234-4925

Denso 234-4925 is an OE Style heated oxygen sensor built for direct replacement on select Lexus and Toyota applications. It is engineered for specific fitment, accurate signal response, and a first-time fit on downstream right and downstream left locations where listed.

Key Features

• Heated oxygen sensor with a specific-fit design
• OE Style construction for direct replacement applications
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 13.07 in. wiring harness length for listed vehicle applications
• Built to OE standards and tested for replacement use
• Uses Denso’s aluminum oxide trap layer to help protect the sensing element from silicone and lead contamination

Product Details

This Denso oxygen sensor is designed for emissions control systems that rely on precise exhaust feedback for fuel and engine management. The OE Style line focuses on exact replacement dimensions and connector layout, which helps simplify service on vehicles such as the Lexus GX460, Lexus ES350, Toyota Avalon, and Toyota Camry. Part number 234-4925 is also cross-referenced to NTK 24560 for the same application.

Compatible With 2020-2021 Lexus GX460, downstream right; 2018-2019 Lexus GX460, downstream right; 2014-2015 Lexus GX460, downstream right; 2018 Lexus ES350, downstream right; 2015 Lexus ES350, downstream right; 2017-2018 Toyota Avalon, downstream right; 2016-2017 Lexus ES350, downstream right; 2016-2017 Lexus GX460, downstream left; 2015-2017 Toyota Camry, downstream right; and 2015-2016 Toyota Avalon, downstream right. If you are searching for a Lexus GX460 downstream oxygen sensor or a Toyota Camry OE style oxygen sensor, this part number 234-4925 matches the listed positions and model years.

What It Helps Address

• Faulty oxygen sensor readings
• Check engine light concerns related to sensor performance
• Rough fuel control caused by inaccurate exhaust feedback
• Reduced fuel economy from a worn downstream sensor
• Emissions system service needs on listed Lexus and Toyota models

Installation Notes

Verify the connector style, wire count, thread diameter, and mounting location before installation. This sensor uses a threaded mount and a 4-wire male connector, so matching the original harness and exhaust port location is important. Confirm whether your vehicle requires the downstream right or downstream left position before ordering.

Quality Assurance

Denso manufactures and tests this sensor to OE standards for replacement use. The OE Style design is intended to provide the correct fit and sensor performance for the listed Lexus and Toyota applications.
