Denso 234-4169 Oxygen Sensor

Denso OE Style Oxygen Sensor 234-4169

Denso 234-4169 is an OE-style heated oxygen sensor built for specific applications that require a direct-fit replacement and accurate exhaust feedback. It is engineered for Lexus LS600h, LX570, GS400, LS400, SC400, LX470, Toyota Land Cruiser, Sequoia, Tundra, and 4Runner applications where precise sensor response matters for drivability and emissions control.

Key Features

• Heated oxygen sensor with specific fitment for direct replacement
• OE Style design for factory-style installation and signal performance
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 11.42 in. wiring harness length for application-specific routing
• Built to OE standards and tested for consistent operation
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

Product Details

The Denso OE Style line focuses on exact replacement fit and factory-level sensor behavior. Part number 234-4169 is manufactured to strict OE standards and is precision built for the specified vehicle applications, helping maintain proper air-fuel feedback to the engine control system. This part cross-references Bosch 13441 and NTK 24560 for the same application. For shoppers searching for a Lexus LS400 upstream oxygen sensor, Toyota Tundra upstream oxygen sensor, or Toyota Land Cruiser downstream right oxygen sensor, this Denso unit matches the listed positions and vehicle coverage.

What This Oxygen Sensor Helps Address

• Check engine light caused by a failing upstream or downstream oxygen sensor
• Rough idle or inconsistent fuel control from inaccurate exhaust readings
• Reduced fuel economy related to delayed sensor response
• Emissions test failures tied to oxygen sensor performance
• Driveability issues on Lexus and Toyota models with OE-style sensor requirements

Installation Notes and Tips

Verify the connector style, wire count, thread diameter, and sensor position before installation. This part is listed for specific positions including upstream, downstream, downstream left, and downstream right depending on the vehicle. Confirm the exact application for your Lexus LS600h, LX570, or Toyota Land Cruiser before ordering, and route the harness to match the original sensor path.
