It is engineered as an OE-style replacement for vehicles that rely on accurate exhaust feedback to help the ECU manage fuel control and emissions monitoring.\u003c\/p\u003e\u003cp\u003eFor a 2024 Ford Explorer downstream oxygen sensor replacement, this Walker part number 250-241336 matches the application-specific fitment and connector layout required for proper system communication.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpecific-fit oxygen sensor for the downstream location\u003c\/li\u003e\n\u003cli\u003eHeated narrow-band design for exhaust feedback monitoring\u003c\/li\u003e\n\u003cli\u003e4-wire configuration with 4 terminals\u003c\/li\u003e\n\u003cli\u003eOblong male connector with female terminals\u003c\/li\u003e\n\u003cli\u003eM18 x 1.5 thread size\u003c\/li\u003e\n\u003cli\u003e20-gauge wire measurement\u003c\/li\u003e\n\u003cli\u003eOE Base Sensor line from Walker Products\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eWalker Products develops engine management and oxygen\/air-fuel sensors as OE replacement parts for a wide range of vehicles. The OE Base Sensor line focuses on application-specific coverage, so the sensor, connector, and fitment position align with the vehicle’s original requirements. On the 2024 Ford Explorer, the downstream oxygen sensor helps provide the ECU with the exhaust data needed for emissions and fuel-control diagnostics. Part number 250-241336 is built for that exact role.\u003c\/p\u003e\u003cp\u003eThis sensor is a practical choice when replacing a failed downstream unit on a 2024 Ford Explorer, especially when the original sensor has triggered a malfunction indicator light or stored fault codes related to exhaust monitoring. Walker 250-241336 is also relevant for buyers searching for a 2024 Ford Explorer downstream oxygen sensor, OE replacement oxygen sensor, or narrow-band O2 sensor with the correct connector and thread specification.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part May 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 inaccurate exhaust feedback\u003c\/li\u003e\n\u003cli\u003eElevated exhaust emissions from a failing downstream sensor\u003c\/li\u003e\n\u003cli\u003eStored ECU fault codes tied to the oxygen sensor circuit\u003c\/li\u003e\n\u003cli\u003eRough engine operation linked to incorrect sensor input\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm the downstream location before installation and compare the connector shape, wire count, and thread size to the original sensor. Inspect the wiring harness and connector for heat damage, corrosion, or broken terminals before replacing the sensor. Because oxygen sensor faults can also be caused by related wiring or exhaust system issues, verify the surrounding components if the warning light returns after replacement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products has manufactured engine management components since 1946 and operates as an ISO 9001\/TS 16949 certified company. The OE Base Sensor line is built around application-specific replacement coverage for accurate fitment and diagnostic feedback on vehicles such as the Ford Explorer. Part number 250-241336 reflects that OE-style approach for the downstream oxygen sensor application.\u003c\/p\u003e","brand":"Walker","offers":[{"title":"Default Title","offer_id":52985192218805,"sku":"DKHD-250-241336","price":112.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/O2_250241336_FRO.jpg?v=1787122298","url":"https:\/\/www.partcatalog.com\/products\/walker-250-241336-oxygen-sensor-downstream","provider":"PartCatalog","version":"1.0","type":"link"}
