Denso OE Style Air/Fuel Ratio Sensor 234-5702

Denso 234-5702 is an OE Style heated air/fuel ratio sensor built for specific-fit replacement on select Volvo applications. It is engineered and tested to OE standards for accurate signal response and a first-time fit on vehicles such as the Volvo C30, C70, S40, S60, S70, S80, V50, and V70.

Key Features

  • Heated air/fuel ratio sensor for precise exhaust feedback
  • Specific-fit design for direct replacement on listed Volvo models
  • 5-wire configuration with male connector
  • Wiring harness length: 23.23
  • Thread diameter: 0.711
  • OE Style line focused on exact replacement fitment

OE Style Design and Fitment

The Denso OE Style line is built around exact replacement requirements, with components precision-made to match the original part’s fit and function. For Volvo upstream sensor service, this Denso air/fuel ratio sensor 234-5702 supports direct replacement needs on 2007-2013 Volvo C30, upstream; 2006-2013 Volvo C70, upstream; 1999 Volvo C70, upstream; 2012 Volvo S60, upstream; 2004-2011 Volvo S40, upstream; 2005-2011 Volvo V50, upstream; 2000-2001 Volvo S80, upstream left; 1999 Volvo S70, upstream; and 1999 Volvo V70, upstream.

This part cross-references Bosch 15176 and NTK 24306 for the same application.

What This Sensor Helps Address

  • Check engine light related to upstream air/fuel ratio sensor faults
  • Incorrect fuel trim readings from a worn sensor
  • Rough idle or hesitation caused by inaccurate exhaust feedback
  • Emissions test failures tied to sensor performance
  • Slow sensor response during closed-loop fuel control

Installation Notes and Tips

Verify the connector style, wire count, and thread diameter before installation. This is a specific-fit heated sensor, so confirm the vehicle position as upstream or upstream left before ordering. For best results, inspect the harness routing and connector condition during replacement, and clear diagnostic trouble codes after installation if required by the vehicle.

Quality Assurance

Denso manufactures and tests this sensor to OE standards for consistent replacement quality and proper fit. The OE Style designation reflects a direct-replacement approach for Volvo upstream sensor service, including applications on the Volvo C30, C70, and S40 platform families.
