Denso 234-4265 Oxygen Sensor Overview
Denso 234-4265 is an OE-style heated oxygen sensor built for specific-fit replacement on select Land Rover applications. It is engineered for accurate exhaust monitoring, stable signal output, and a first-time fit on the vehicles listed below.
Compatible with 2005-2006 Land Rover LR3, downstream right; 2006 Land Rover Range Rover Sport, downstream right; and 2007-2009 Land Rover Range Rover, downstream.
Key Features
- Heated oxygen sensor design for faster operating temperature and consistent feedback
- Specific-fit replacement for direct installation on listed Land Rover models
- 4-wire configuration with male connector
- Threaded mounting with 0.708 in. thread diameter
- 14.76 in. wiring harness length for OE-style routing
- OE Style construction from Denso for exact replacement fit
OE Style Construction
Denso’s OE Style line is built to match original equipment fit and function for the application. The 234-4265 uses precision-built components and Denso’s aluminum oxide trap layer to help protect the sensing element from silicone and lead contamination, supporting reliable exhaust readings and long service life. This part cross-references Bosch 13498 and NTK 25646 for the same application.
Used For These Symptoms
- Check engine light related to oxygen sensor performance
- Incorrect air-fuel ratio feedback from the downstream sensor
- Reduced fuel economy caused by inaccurate exhaust data
- Slow sensor response or degraded signal output
- Failed emissions inspection tied to sensor fault codes
Installation Notes
Verify the connector style, wire count, thread diameter, and sensor position before installation. This sensor is listed for downstream and downstream right locations only, so confirm the exact placement on your Land Rover LR3, Range Rover Sport, or Range Rover before ordering. Use proper exhaust sensor removal tools and inspect the harness routing to avoid strain on the lead.
Quality Assurance
Denso manufactures and tests this oxygen sensor to OE standards for fit and performance consistency. The OE-style design is intended to deliver the correct part and fit for the listed applications.
