Denso 234-8010 Oxygen Sensor - Downstream

Denso OE Style Oxygen Sensor 234-8010

Denso 234-8010 is an OE Style heated oxygen sensor built for direct replacement on select Volvo applications. It is engineered for specific fitment, threaded mounting, and a 4-wire male connector to match the original sensor layout on downstream locations.

For Volvo S60, V60, V60 Cross Country, XC90, V90, V90 Cross Country, XC60, and S90 applications, this sensor is designed to restore accurate exhaust feedback after the catalytic converter. The Denso OE Style line focuses on exact replacement fit and OE-level construction for straightforward service work.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific-fit design for direct replacement on listed Volvo models
• Threaded mounting type with 0.709 in. thread diameter
• 4-wire configuration with male connector
• 14.76 in. wiring harness length
• Denso OE Style replacement part number 234-8010

OE Style Construction

Denso’s OE Style oxygen sensor line is built to match original equipment dimensions and electrical requirements for a first-time fit. The sensor uses an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable sensor operation and long service life. If you are replacing a downstream oxygen sensor on a Volvo S60, Volvo XC90, or Volvo V60, Denso 234-8010 provides the OE-style configuration needed for a clean repair.

This part cross-references Volvo 31422307 and 31480395 for the same application.

What This Sensor Helps Address

• Check engine light related to downstream oxygen sensor performance
• Incorrect exhaust oxygen readings after the catalytic converter
• Reduced fuel economy caused by faulty sensor feedback
• Rough or inconsistent engine operation tied to emissions sensor faults
• Failed emissions inspection due to oxygen sensor issues
