Denso 234-4906 Oxygen Sensor - Downstream

Denso OE Style Oxygen Sensor 234-4906

Denso 234-4906 is an OE Style heated oxygen sensor built for direct replacement on select Nissan and INFINITI applications. It is engineered for a specific fit and uses a threaded mounting design with a 4-wire male connector for straightforward replacement on the listed downstream positions.

Key Features

• OE Style replacement oxygen sensor for downstream applications
• Heated sensor design for faster operating response
• Specific fit for the listed Nissan and INFINITI vehicles
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 11.46 in. wiring harness length

OE Style Construction

Denso’s OE Style line is built to match original equipment fit and function, with precision construction for direct replacement. The sensor uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management performance and long service life. This part number, 234-4906, is a direct-fit oxygen sensor for downstream service on select Nissan Rogue, Frontier, Murano, Pathfinder, Xterra, and INFINITI QX60 applications.

This part cross-references NTK 24056 for the same application.

• Restoring proper air-fuel feedback for engine control
• Correcting poor fuel economy caused by inaccurate exhaust readings
• Replacing a damaged or contaminated OE-style sensor on Nissan and INFINITI models

Installation Notes

Verify the connector style, wire count, thread diameter, and downstream location before installation. Match the vehicle application exactly, since this is a specific-fit sensor rather than a universal part. Confirm the harness routing and sensor position on the exhaust system before final tightening.

Quality Assurance

Denso manufactures and tests its oxygen sensors to OE standards for replacement accuracy and consistent performance. The OE Style design is intended to provide the correct fit and function for the listed applications, including Nissan Rogue, Frontier, Murano, Pathfinder, Xterra, and INFINITI QX60 models.
