Denso 234-2038 Oxygen Sensor - Downstream

Denso OE Style Oxygen Sensor 234-2038

Denso 234-2038 is an OE Style oxygen sensor built for direct replacement on select Jaguar applications. It is a specific-fit, non-heated sensor with a threaded mounting design and a male connector for straightforward OE-style service on downstream locations.

Key Features

• OE Style replacement oxygen sensor from Denso
• Specific fit for select Jaguar XK8, XJ8, XJR, and Vanden Plas applications
• Non-heated sensor design
• Threaded mounting type with 0.708 in. thread diameter
• 2-wire configuration with male connector
• Wiring harness length: 19.65 in.

OE Style Design and Construction

Denso’s OE Style line is built and tested to OE-level standards for accurate replacement fitment and consistent sensor performance. The 234-2038 oxygen sensor uses precision-built components to match the original application, helping maintain proper exhaust feedback on downstream systems. Denso also incorporates an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting long service life and stable engine management.

This part cross-references Jaguar LJA1680AE for the same application.

Vehicle Fitment

• Fits 1997-1999 Jaguar XK8, downstream.
• Fits 1998 Jaguar Vanden Plas, downstream.
• Fits 1998 Jaguar XJ8, downstream.
• Fits 1998 Jaguar XJR, downstream.

Common Replacement Reasons

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a worn downstream sensor
• Reduced fuel economy caused by inaccurate exhaust feedback
• Slow or inconsistent sensor response during emissions monitoring
• Corrosion or connector damage at the original sensor location

Installation Notes

Confirm downstream placement before ordering and match the connector, thread diameter, and wire count to the original part. Because this is a specific-fit sensor, it should be installed on the listed Jaguar XK8, XJ8, XJR, or Vanden Plas applications only. Verify the harness routing and connector orientation during installation to avoid strain on the lead.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for exact replacement fitment and consistent operation. The OE Style design is intended to deliver the correct part and fit for the listed Jaguar applications, with construction focused on durability and accurate sensor response.
