Denso 234-4297 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Denso OE Style Oxygen Sensor 234-4297

Denso 234-4297 is an OE Style heated oxygen sensor built for direct replacement on select Nissan and Suzuki applications. It is engineered for specific fitment, threaded mounting, and a 4-wire male connector to match the original sensor layout on downstream positions.

For drivers searching for a downstream oxygen sensor for Nissan Frontier, Pathfinder, Xterra, or NV-series vans, this Denso oxygen sensor is built to match the original connection and mounting style. The 234-4297 part number is also a direct reference for buyers comparing OE-style replacement options.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific-fit design for direct replacement applications
• 4-wire configuration with male connector
• Threaded mounting with 0.708 in. thread diameter
• 10.83 in. wiring harness length for OE-style routing
• Built to Denso OE standards for replacement accuracy
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

OE Style Construction

Denso’s OE Style line focuses on exact replacement fit and original-equipment performance characteristics. This oxygen sensor is precision built for the intended application, helping maintain proper exhaust feedback for the engine control system. The protective trap layer is part of Denso’s sensor design and supports long service life in demanding exhaust environments.

This part cross-references Bosch 16513 and NTK 24244 for the same application.

Common Replacement Uses

• Replacing a failed downstream oxygen sensor on Nissan Frontier, Pathfinder, or Xterra
• Correcting oxygen sensor fault codes related to exhaust feedback
• Restoring proper air-fuel monitoring after sensor aging or contamination
• Addressing drivability issues tied to inaccurate exhaust oxygen readings
• Replacing a damaged threaded sensor or worn connector on OE-style applications

Installation Notes

Confirm the downstream left, downstream, or downstream right position before ordering, since this part is position-specific. Verify connector style, wire count, and thread diameter against the original sensor, and inspect the exhaust bung threads before installation. Use the vehicle’s service procedure for sensor removal and torque specification.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for replacement accuracy and consistent fit. The OE Style design is intended to deliver the correct part and the correct fit for the listed applications.
