Product Details

Denso 234-9076 is engineered and tested to OE standards for consistent sensor performance and proper fitment. As part of Denso’s OE Style line, this sensor is built as a direct replacement for the original equipment design, helping maintain correct air-fuel monitoring on 2006-2011 Acura CSX upstream applications and 2006-2011 Honda Civic upstream applications. This part cross-references Honda (e.g., 36531RRA003, 36531RRA013) 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 failing upstream sensor
• Emissions test failures tied to sensor response problems
• Driveability concerns on 2006-2011 Honda Civic and Acura CSX upstream systems

Installation Notes and Tips

Verify the connector style, wire count, and thread diameter before installation. This sensor is a specific-fit upstream unit, so match the vehicle year, make, model, and position exactly to the listed applications. For best results, inspect the harness routing and connector condition during replacement on Honda Civic and Acura CSX applications.

Quality Assurance

Denso manufactures and tests this OE Style sensor to strict original-equipment standards. The design focuses on exact replacement dimensions and proper fit for the listed upstream applications.
