Denso 234-4260 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

OE-Style Oxygen Sensor for Toyota and Lexus

This Denso OE Style oxygen sensor is a direct-fit, heated replacement built for specific applications in Toyota and Lexus vehicles. Part number 234-4260 is engineered for accurate exhaust monitoring, stable engine management, and a first-time fit on the listed downstream positions.

Designed for 2003-2016 Toyota and Lexus applications, this sensor supports the downstream left and downstream right locations called out in the fitment data. If you are replacing a worn sensor on a Toyota Tundra, Toyota Sequoia, or Lexus GX460, 234-4260 provides an OE-style solution matched to the original connector and mounting design.

Key Features

• Heated oxygen sensor for specific-fit applications
• OE Style design for direct replacement
• 4-wire configuration with male connector
• Threaded mounting type with 0.708 in. thread diameter
• 9.45 in. wiring harness length
• Built and tested to OE standards for fit and function
• Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

Product Details

Denso 234-4260 is part of the OE Style line, which focuses on exact replacement geometry and application-specific fitment. The sensor is precision built to match the original installation points on vehicles such as the Toyota Camry, Toyota Tacoma, Toyota 4Runner, Lexus ES350, and Toyota Land Cruiser. This helps maintain proper exhaust feedback for the engine control system and supports consistent drivability across the covered model years.

This part cross-references Bosch 15104 and NTK 24453 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a failing downstream sensor
• Reduced fuel economy caused by inaccurate exhaust readings
• Rough idle or drivability issues tied to sensor degradation
• Slow response from a contaminated or aged heated oxygen sensor
