Product Details

Denso OE Style parts are built to match original equipment requirements for fit and function. This air/fuel ratio sensor is designed for the upstream location on 2011-2013 Nissan Altima models, excluding California emissions applications. The Denso 234-9107 follows the correct sensor type, harness length, and wire count for a direct replacement in the specified application.

This part cross-references Datsun/Nissan 22693ZX00A and NTK 24854 for the same application.

What It Helps Address

• Check engine light related to air/fuel ratio sensor faults
• Rough idle caused by inaccurate exhaust feedback
• Fuel trim issues from a slow or failing upstream sensor
• Emissions test failures tied to sensor performance
• Poor drivability from incorrect air/fuel mixture readings

Installation Notes

Fits 2011-2013 Nissan Altima, upstream. Verify the vehicle is an exclusion-free application before ordering, since this listing does not cover California emissions models. Match the connector, wire count, and harness length to the original sensor before installation.

Quality Assurance

Denso manufactures and tests this OE Style sensor to original-equipment standards for consistent replacement fit and performance. The precision-built design supports first-time fitment in the specified Nissan Altima application.
