Product Details

Walker Products OE focuses on engine management and oxygen/air-fuel sensors built as OE-style replacements for many vehicles worldwide. This sensor is manufactured for the specified application and fitment position so the ECU receives the diagnostic feedback required for proper operation. On vehicles such as the Toyota Tacoma, Toyota Avalon, Toyota Camry, Toyota RAV4, and Lexus ES350, an upstream oxygen sensor plays a direct role in air-fuel control, emissions performance, and fault-code monitoring.

Walker Products has supplied engine management and fuel system components since 1946 and operates with ISO 9001/TS 16949 quality systems. Part 250-54113 is intended for the exact sensor location listed below, including upstream, upstream right, upstream left, and upstream rear positions where specified.

What This Sensor Helps Address

• Check engine light or MIL related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel correction
• Higher exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

• Verify the exact year, make, model, and sensor position before ordering.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Confirm the threaded mounting location and connector orientation match the original sensor.
• Use the listed upstream position only where the fitment table specifies it for your vehicle.
• For Toyota Tacoma applications, confirm whether your vehicle requires upstream, upstream left, or upstream right placement.

Quality Assurance

Walker Products OE sensors are engineered as replacement parts for specific vehicle applications and are produced under ISO 9001/TS 16949 quality standards. This part number is built to support the diagnostic needs of the ECU in the listed Toyota and Lexus fitments.
