Overview

The Denso 234-4138 oxygen sensor is a purpose-built replacement designed for select Lexus and Toyota vehicles. This narrow-band O2 sensor combines a robust stainless steel body with a refined sensing element, engineered to meet OE-style performance. The result is a dependable part that aims to deliver consistent readings and a straightforward, first-time fit.

Compatibility and Applications

Application coverage includes Lexus GS430 (2001-2007), GX470 (2003-2004), LS430 (2001-2006), LX470 (2003-2005), SC430 (2002-2010); and Toyota 4Runner (2003-2004, 2010-2012), FJ Cruiser (2010-2012), Land Cruiser (2003-2005).

Key Features

  • Denso 4-wire O2 sensor with an 8.27 inch wiring harness
  • Part Number: 234-4138
  • Interchange options: 8946560430, 8946550120, 8946560150
  • Corrosion-resistant stainless steel construction
  • PTFE filter blocks contaminants that can affect efficiency
  • Refined zirconia element for improved sensor response
  • Package Quantity: 1
  • Dimensions: 5.75 x 2.19 x 1.88 inches; Weight: 0.25 pounds

Why This Sensor Stands Out

Manufactured and tested to strict OE standards, this sensor is designed to install with a precise fit the first time. An exclusive aluminum oxide trap layer helps shield the ceramic element from silicone and lead contaminants, potentially supporting stable readings and longer service life.

  • Right part, right fit for listed models
  • Sturdy build and protective features designed for durability
  • Installation designed for a straightforward, confident replacement

Real-World Scenarios

In everyday driving scenarios—city commutes, highway cruising, and routine maintenance cycles—the 234-4138 sensor can contribute to balanced fuel readings and steady engine behavior. Results may vary by vehicle and driving conditions, but many users value the sensor’s robust construction and compatibility.

Note: While the sensor is engineered to support reliable operation, individual outcomes depend on the broader vehicle system and driving environment. The manufacturer emphasizes a first-time fit and OE-standard quality, offering a dependable option for those replacing a worn or failing O2 sensor.
