Walker 350-34336 Oxygen Sensor for Land Rover

Walker Products 350-34336 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Land Rover applications. It is engineered to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring on downstream bank 1 sensor 2 locations.

Key Features

• Heated oxygen sensor for faster operating response
• Specific fitment for the listed Land Rover applications
• Threaded mounting design with 18.0 mm thread diameter
• 4-wire configuration with 22-gauge wiring
• Radiused polygon male connector for application-specific connection
• Wiring harness length: 16.26 in.; overall length: 19.8 in.

Product Details

The Walker Products Aftermarket line focuses on engine management and oxygen/air-fuel sensors developed for OE replacement use. Part number 350-34336 is built for downstream bank 1 sensor 2 service on select 2012-2013 Land Rover Range Rover Evoque and 2013-2015 Land Rover LR2 models. For buyers searching for a downstream oxygen sensor for Land Rover LR2 or a heated O2 sensor for Range Rover Evoque, this application-specific design helps maintain the diagnostic feedback expected by the ECU. Walker Products 350-34336 is also a direct-fit option for technicians replacing a failed sensor that has triggered a MIL, poor fuel economy, or elevated exhaust emissions.

Walker Products has supplied engine management components since 1946 and manufactures sensors for specific vehicle applications and mounting positions. This part cross-references no listed aftermarket part numbers in the provided data.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation tied to incorrect air-fuel correction
• Elevated exhaust emissions from a failing sensor
• Diagnostic trouble codes stored in the ECU for sensor circuit issues

Installation Notes

Confirm the vehicle uses the downstream bank 1 sensor 2 position before ordering. Inspect the sensor connector, wiring harness, and surrounding exhaust routing for heat damage or physical wear during replacement. Threaded installation requires the correct fitment position and proper sensor engagement to avoid exhaust leaks or connector strain.

Quality Assurance

Walker Products manufactures this sensor as an OE replacement for the specified application and builds it under ISO 9001/TS 16949 quality systems.
