Walker Products OE Oxygen Sensor for Toyota and Lexus
Walker Products OE Part Number 250-54085 is a heated oxygen sensor built for specific upstream applications on select Toyota and Lexus vehicles. It is engineered to deliver the ECU feedback needed for accurate fuel control and emissions monitoring on vehicles such as the Toyota Tundra, Toyota Sequoia, Lexus GX460, and Lexus LX570.
Key Features
- Heated oxygen sensor for upstream placement
- Specific-fit design for direct application matching
- 4-wire configuration with 20-gauge wiring
- Radiused polygon male connector for vehicle-specific connection
- Threaded mounting with 18.0 mm thread diameter
- Overall length: 7.99 in.; wiring harness length: 4.45 in.
Product Details
Walker Products OE focuses on original-equipment-style engine management components, and the 250-54085 oxygen sensor follows that approach with application-specific fitment and position-specific calibration. This sensor is used in upstream locations where the ECU relies on exhaust-gas feedback to manage air-fuel ratio, fuel economy, and emissions performance. It is a direct replacement choice for Toyota Tundra upstream oxygen sensor service, Toyota Sequoia upstream oxygen sensor replacement, and Lexus GX460 or LX570 upstream sensor repair.
This part cross-references Denso 234-9005 for the same application.

Installation Notes and Tips
Confirm the sensor position before installation, since this part is listed for upstream right, upstream left, and upstream applications depending on vehicle and build date. Inspect the connector, wiring harness, and surrounding exhaust components for heat damage or corrosion before replacement. Verify thread size and connector shape against the original sensor to ensure proper installation on the Toyota Tundra, Toyota Sequoia, or Lexus GX460 application.
