Detailed Product Information

Denso 234-5060 is an upstream air/fuel ratio sensor designed for precise replacement where accurate mixture feedback is required. The OE Style line focuses on exact replacement fitment, and this sensor is manufactured for the right fit the first time on specific Nissan and INFINITI platforms. It cross-references Bosch 17204 and NTK 24320 for the same application.

Compatible With 2004-2008 Nissan Maxima, Upstream; 2004-2007 Nissan Murano, Upstream; 2004-2009 Nissan Quest, Upstream; 2005-2006 Nissan Altima, Upstream; 2006-2010 INFINITI M45, Upstream; and other listed upstream applications including FX45, Q45, QX56, Armada, Frontier, Pathfinder, TITAN, Xterra, Pathfinder Armada, and Sentra.

Common Issues This Sensor May Address

• Check engine light related to air/fuel ratio sensor performance
• Rough idle caused by inaccurate upstream exhaust feedback
• Fuel trim concerns from a worn or slow-responding sensor
• Emissions test failures tied to sensor signal issues
• Driveability problems on Nissan and INFINITI upstream sensor applications

Installation Notes and Tips

Confirm the connector style, wire count, thread diameter, and upstream location before installation. This sensor is a specific-fit part, so matching the vehicle year, make, model, and production notes is important; for example, some 2006 INFINITI FX45 and Q45 applications require production-date verification. Use the exact vehicle listing for 2004-2006 Nissan QX56, 2004-2006 Nissan TITAN, and related upstream applications before ordering.

Quality Assurance

Denso manufactures and tests this sensor to OE standards for replacement accuracy and fit. The OE Style product line is focused on direct replacement parts that match the original application requirements for Nissan and INFINITI upstream sensor locations.
