The sensor is intended to provide the ECU with the correct feedback for emissions and engine management monitoring, which is important when replacing a failed downstream rear or downstream side sensor. The 250-241334 is a heated, narrow-band unit with a 4-wire configuration, built for specific fitment rather than universal use.\u003c\/p\u003e\u003cp\u003eCompatible With 2025 Ford Mustang, downstream rear; 2024 Ford Mustang, downstream; 2024 Ford F-150, downstream right; 2021-2023 Ford Bronco, downstream left; and 2021-2023 Ford F-150, downstream right. This part number, 250-241334, is also a fitment-specific option for Ford Mustang and Ford F-150 oxygen sensor replacement where the original sensor location and connector style must match.\u003c\/p\u003e\u003cp\u003eWalker Products has supplied engine management and oxygen\/air-fuel sensors since 1946 and manufactures application-specific replacement parts for modern diagnostic systems.
