This sensor is used in downstream positions on select Ford trucks, including the Ford F-150, Ford F-250 Super Duty, and Ford F-350 Super Duty. The narrow-band design and heated construction support proper sensor operation in the intended exhaust location.\u003c\/p\u003e\u003cp\u003eThis part cross-references no listed aftermarket part numbers for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine light related to downstream oxygen sensor performance\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy caused by incorrect exhaust feedback\u003c\/li\u003e\n\u003cli\u003eRough engine operation tied to sensor signal issues\u003c\/li\u003e\n\u003cli\u003eIncreased exhaust emissions from a failing oxygen sensor\u003c\/li\u003e\n\u003cli\u003eFault codes stored in the ECU for the affected sensor circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eCompatible With 2023-2025 Ford F-250 Super Duty, downstream right; 2023-2025 Ford F-350 Super Duty, downstream right; 2021-2023 Ford F-150, downstream right; 2022 Ford F-250 Super Duty, downstream left; and 2022 Ford F-350 Super Duty, downstream left. Verify the connector, wiring harness, and sensor location before installation, and inspect the exhaust bung threads for the correct M18 x 1.5 fitment. If the original sensor failed from wiring or connector damage, inspect those components before replacing the sensor.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products has produced engine management and fuel system components since 1946 and operates as an ISO 9001\/TS 16949 certified company.
