Walker 250-24305 Oxygen Sensor

Walker OE Oxygen Sensor for Toyota and Lexus

Walker Products OE oxygen sensor Part Number 250-24305 is a specific-fit, heated sensor built for downstream and upstream applications on select Toyota and Lexus vehicles. It is engineered to deliver the ECU feedback needed for accurate fuel control and emissions monitoring.

Use this Walker Products OE sensor when servicing a Toyota Tundra downstream right oxygen sensor, a Toyota Tacoma downstream bank 1 sensor 2 application, or select Lexus GS300 and SC300 upstream/downstream positions.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed vehicle positions
• 4-wire configuration with a 20-gauge harness
• Radiused polygon male connector for OE-style connection
• Threaded mounting with 18.0 mm thread diameter
• Overall length: 20.0; wiring harness length: 16.46
• Walker Products OE line for application-matched replacement fitment

Detailed Description

Walker Products OE Part Number 250-24305 is engineered as an Original Equipment replacement oxygen sensor for targeted Toyota and Lexus applications. The sensor is built for the exact fitment position on the vehicle, including downstream right, downstream front, downstream, and upstream locations depending on the model and year. This helps the ECU receive the correct diagnostic feedback for emissions and fuel-trim control.

Fitment includes 2019 Toyota Tundra downstream right, 2007-2018 Toyota Tundra downstream right, 2008-2017 Toyota Sequoia downstream right, 2012-2014 Toyota Tacoma downstream, 2005-2010 Toyota Tacoma downstream, 2000-2005 Lexus GS300 downstream, and 1993-1997 Toyota Supra and Lexus SC300 upstream applications. Part number 250-24305 is also listed for select 2015 Toyota Venza downstream front and 2014-2016 Toyota Tundra downstream right configurations.

This part cross-references no listed alternate part numbers in the provided data.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes and Tips

• Confirm the exact year, model, engine configuration, and sensor position before ordering.
• Match the installation location exactly: downstream right, downstream front, downstream, or upstream as listed.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Check the exhaust bung threads and sensor mounting surface for damage prior to threading in the new sensor.
• Verify the connector shape and wire count against the original sensor for proper OE-style fitment.

Quality Assurance

Walker Products OE sensors are developed as OE-style replacements for specific vehicle applications and are manufactured under Automotive ISO9001/TS 16949 quality systems. The Walker Products OE line is focused on application-specific engine management and oxygen sensor coverage for Toyota Tundra, Toyota Tacoma, Toyota Sequoia, Lexus GS300, Lexus SC300, Toyota Supra, and Toyota Venza fitments.
