Detailed Description

This Denso oxygen sensor is designed for downstream use on 1999-2004 Land Rover Discovery, 1999-2002 Land Rover Range Rover, and 2002-2005 Land Rover Freelander applications. The Denso 234-4696 follows OE-style construction for a first-time fit and consistent sensor response, making it a practical choice when replacing a worn or slow-responding exhaust sensor. This part cross-references ACDelco 213-2925 and Bosch 15630 for the same application.

Denso’s OE Style line focuses on exact replacement geometry and tested performance. The sensor’s heated design helps it reach operating temperature quickly, while the protective trap layer is intended to reduce contamination-related wear and support long service life. For buyers searching for a downstream oxygen sensor for Land Rover Discovery, Range Rover, or Freelander, Denso 234-4696 provides a direct-fit solution matched to the listed vehicles.

What It Helps Address

• Check engine light caused by a failing downstream oxygen sensor
• Rough idle or inconsistent fuel control from inaccurate exhaust readings
• Reduced fuel economy linked to slow sensor response
• Emissions test failures related to sensor performance
• Driveability issues from contaminated or aging oxygen sensor elements

Installation Notes and Tips

Verify the connector style, threaded mounting, and harness length before installation. This sensor is specific fit and is listed for downstream positions only, so confirm the vehicle year, model, and exhaust location before ordering. Inspect the harness routing and connector condition during replacement to avoid strain or poor electrical contact. For best results, compare the original sensor location and connector layout with the new part before final installation.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for consistent replacement quality and fit. The OE Style design is built to match the original application requirements on the listed Land Rover models, including 1999-2004 Discovery, 1999-2002 Range Rover, and 2002-2005 Freelander.
