Part number 250-54084 is used in upstream oxygen sensor locations on vehicles such as the Subaru BRZ, Subaru Crosstrek, Subaru Forester, Subaru Impreza, Toyota 86, Toyota Camry, Toyota RAV4, Toyota Tacoma, Lexus ES350, Lexus RX350, and Scion FR-S. This part number 250-54084 is also listed for additional Toyota and Lexus upstream positions, including front, rear, and right-side applications where specified by the vehicle.\u003c\/p\u003e\u003cp\u003eAs an oxygen sensor for Subaru BRZ upstream replacement and Toyota Camry upstream oxygen sensor service, this unit supports the ECU’s ability to monitor exhaust oxygen content and adjust fuel delivery. Walker Products has supplied engine management components since 1946 and manufactures sensors for specific vehicle fitments rather than universal use.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine light related to oxygen sensor performance\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy caused by incorrect air-fuel feedback\u003c\/li\u003e\n\u003cli\u003eRough engine operation from inaccurate exhaust readings\u003c\/li\u003e\n\u003cli\u003eElevated exhaust emissions from a failing upstream sensor\u003c\/li\u003e\n\u003cli\u003eFault codes stored in the ECU for sensor or related system issues\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConfirm the exact position before ordering: upstream, upstream front, upstream rear, or upstream right as listed.\u003c\/li\u003e\n\u003cli\u003eInspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.\u003c\/li\u003e\n\u003cli\u003eVerify thread size and connector style match the original sensor on the vehicle.\u003c\/li\u003e\n\u003cli\u003eUse the vehicle’s service information for torque and routing details.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products OE sensors are manufactured as application-specific replacements and produced by an ISO 9001 \/ TS 16949 certified company.
