Denso OE Style Oxygen Sensor 234-4704

Denso 234-4704 is a specific-fit heated oxygen sensor built for direct replacement in select Nissan and INFINITI applications. It is engineered to match OE-style dimensions and connector layout for a first-time fit on downstream right locations.

For drivers searching for a 1996-2000 Nissan Pathfinder downstream right oxygen sensor, 1997-2000 INFINITI QX4 downstream right oxygen sensor, or 1999-2003 Nissan Frontier downstream right oxygen sensor, this Denso OE Style sensor provides the correct fitment profile.

Key Features

  • Heated oxygen sensor for downstream right placement
  • Specific-fit design for direct replacement applications
  • 4-wire configuration with male connector
  • Threaded mounting type with 0.708 in. thread diameter
  • 36.22 in. wiring harness length
  • OE Style construction for factory-matched fit and function

OE Style Construction

Denso’s OE Style line is built to match original equipment requirements for fit, form, and function. The sensor uses a precision-built design and an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination, supporting stable engine management performance and long service life. Denso 234-4704 is a practical choice when you need a direct replacement oxygen sensor for Nissan Frontier, Nissan Xterra, Pathfinder, or INFINITI QX4 applications.

This part cross-references Bosch 13226 and NTK 24544 for the same application.

What This Sensor Helps Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel mixture readings from a worn downstream sensor
  • Reduced fuel economy caused by inaccurate exhaust feedback
  • Slow sensor response from age, heat, or contamination
  • Emissions test failures tied to sensor degradation

Installation Notes

Verify the downstream right location before ordering and compare the connector, wire count, and thread size to the original sensor. Use the vehicle’s service procedure for removal and installation, and confirm the harness routing keeps the lead away from exhaust heat and moving components. This sensor is a specific-fit replacement for the listed Nissan and INFINITI applications, including 1996-2000 Nissan Pathfinder, 1997-2000 INFINITI QX4, 1999-2003 Nissan Frontier, and 2000-2003 Nissan Xterra.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for replacement accuracy and consistent performance. Part number 234-4704 is designed to deliver the correct fit and function for the listed applications, including Nissan Pathfinder and Nissan Frontier models.
