Denso 234-4595 Oxygen Sensor - Downstream Front or Downstream Left

Denso OE Style Oxygen Sensor 234-4595

Denso 234-4595 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 4-wire, threaded design with a female connector and 10.79-inch wiring harness length.

For drivers searching for a downstream oxygen sensor for 2013-2014 Nissan Altima, Murano, Pathfinder, or Quest, this Denso sensor is built to match the original configuration and mounting style. It also fits 2013 INFINITI JX35 and 2014 INFINITI QX60 in the listed downstream positions.

Key Features

• OE Style replacement oxygen sensor for direct-fit service
• Heated sensor design for faster operating response
• Specific fit application for the listed Nissan and INFINITI vehicles
• 4-wire construction with female connector
• Threaded mounting type with 0.708-inch thread diameter
• 10.79-inch wiring harness length for factory-style routing
• Part number 234-4595 for easy identification

OE Style Design and Construction

Denso’s OE Style line is built to match original equipment dimensions and electrical requirements for a first-time fit. This oxygen sensor uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable sensor operation and long service life. The result is a direct replacement that aligns with the factory sensor layout on the Nissan Altima, Murano, Pathfinder, Quest, and INFINITI JX35 and QX60 applications listed below.

This part cross-references Datsun/Nissan 226A01HC0A and NTK 24466 for the same application.

What This Oxygen Sensor Helps Address

• Check engine light concerns 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 after contamination or age-related wear
• Factory-fit replacement needs for downstream left or downstream front locations

Installation Notes and Fitment

• Fits 2014 INFINITI QX60, downstream left
• Fits 2013-2014 Nissan Altima, downstream front
• Fits 2012-2014 Nissan Murano, downstream left
• Fits 2013-2014 Nissan Pathfinder, downstream left
• Fits 2012-2014 Nissan Quest, downstream left
• Fits 2013 INFINITI JX35, downstream left

Verify the connector style, threaded mounting, and sensor position before installation. This Denso oxygen sensor is a specific-fit replacement, so matching the vehicle year, model, and downstream location is important for proper installation and operation. The part number 234-4595 is the reference to confirm the correct application.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for replacement accuracy and consistent performance. The OE Style design focuses on exact fitment, factory-style electrical connection, and contamination resistance for dependable service on the listed Nissan and INFINITI vehicles.
