Denso 234-4794 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

OE-Style Oxygen Sensor for Jaguar and Land Rover

Denso 234-4794 is a heated, specific-fit oxygen sensor built for direct replacement in select Jaguar and Land Rover applications. It is engineered for downstream locations and uses OE-style construction to support accurate exhaust monitoring on vehicles such as the Jaguar F-Type, XF, XJ, and Land Rover Range Rover Sport.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct replacement on listed applications
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 12.01 in. wiring harness length for OE-style routing
• Built to OE standards for exact replacement fit and function
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

Product Details

Denso OE Style oxygen sensors are manufactured and tested to OE-level standards for consistent performance and first-time fitment. Part number 234-4794 is a downstream sensor designed for select Jaguar and Land Rover models, including downstream right, downstream left, and downstream center applications where listed. This part cross-references Bosch 16022 and NTK 25752 for the same application. The Denso OE Style line focuses on precise replacement dimensions and durable sensor protection, helping maintain proper exhaust feedback on vehicles such as the Jaguar F-Type and Jaguar XF.

Common Problems This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect downstream exhaust readings
• Reduced fuel economy caused by faulty sensor feedback
• Rough emissions monitoring from a worn heated O2 sensor
• Replacement needs after sensor contamination or age-related failure

Installation Notes and Tips

Verify the connector style, wire count, thread diameter, and sensor position before installation. This Denso 234-4794 is a specific-fit, threaded sensor, so matching the listed downstream location is important for proper installation. Confirm vehicle application by year, make, model, and position before ordering, especially on Jaguar XF, XJ, and F-Type models where multiple downstream positions are listed.

Quality Assurance

Denso manufactures this oxygen sensor to strict OE standards and tests each component for replacement accuracy and fit. The design includes an aluminum oxide trap layer to help shield the sensing element from silicone and lead contamination, supporting long-term sensor durability and stable engine management performance.
