Denso 234-4452 Oxygen Sensor - Downstream

OE-Style Oxygen Sensor for Volvo

This Denso OE Style oxygen sensor is a specific-fit replacement built for downstream use on select 2002 Volvo S60 and V70 applications. Part number 234-4452 is engineered to match the original sensor layout for accurate installation and dependable exhaust monitoring.

Designed for the 2002 Volvo S60 downstream oxygen sensor and 2002 Volvo V70 downstream oxygen sensor applications, this heated sensor supports precise air-fuel feedback after the catalytic converter. Denso 234-4452 is built to OE-style dimensions for a first-time fit and consistent signal performance.

Key Features

• OE Style replacement oxygen sensor for specific-fit applications
• Heated sensor design for faster operating readiness
• 4-wire configuration with male connector
• Threaded mounting with 0.708 in. thread diameter
• 33.86 in. wiring harness length for proper routing
• Built to strict OE standards for replacement accuracy
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

Detailed Description

Denso 234-4452 is an emission control oxygen sensor made for downstream placement on the 2002 Volvo S60 and 2002 Volvo V70. As part of Denso’s OE Style line, it is precision built to match original fitment requirements and support accurate exhaust-gas feedback. The heated design helps the sensor reach operating temperature efficiently, while the threaded mounting and specific-fit connector simplify replacement on the intended Volvo applications.

This part cross-references Bosch 15695 and NTK 25619 for the same application. It is a direct-fit option for drivers searching for a 2002 Volvo S60 downstream oxygen sensor or 2002 Volvo V70 downstream oxygen sensor, and the part number 234-4452 is commonly used when replacing the original sensor with an OE-style equivalent.

What It Helps Address

• Check engine light concerns related to downstream oxygen sensor performance
• Incorrect exhaust oxygen readings affecting fuel control
• Reduced fuel efficiency caused by a worn sensor
• Slow sensor response after warm-up
• Replacement needs for a damaged or aging Volvo downstream sensor

Installation Notes and Tips

Verify downstream placement before installation and confirm connector style, wire count, and thread size match the original sensor. Route the 33.86 in. harness away from hot exhaust components and inspect the mounting threads for damage before tightening. For best results, compare the old sensor to Denso 234-4452 before installation on the Volvo S60 or Volvo V70.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for replacement accuracy and consistent performance. The OE Style product line focuses on exact-fit components built to match original equipment requirements.
