It is also listed for select Scion models such as the iQ, xD, and Prius C-related fitments. This part number is built to match the required sensor location and provide the diagnostic feedback the ECU expects for emissions and fuel-trim control.\u003c\/p\u003e\u003cp\u003eAs an OE-style replacement, this sensor is intended for vehicles where the original upstream oxygen sensor has failed, triggered a malfunction indicator light, or caused drivability and emissions concerns. Walker Products 350-64073 is part of the Walker Products Aftermarket engine management line, which is focused on application-specific sensor replacement for modern fuel-injected vehicles.\u003c\/p\u003e\u003cp\u003eThis part cross-references Denso 234-9041 and NTK 24302 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine light related to upstream oxygen sensor faults\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy from incorrect air-fuel feedback\u003c\/li\u003e\n\u003cli\u003eRough running or inconsistent engine performance\u003c\/li\u003e\n\u003cli\u003eElevated exhaust emissions from a failing sensor\u003c\/li\u003e\n\u003cli\u003eStored ECU fault codes tied to sensor circuit or response issues\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConfirm the exact year, make, model, and sensor position before ordering.\u003c\/li\u003e\n\u003cli\u003eMatch the upstream location shown in the fitment data, including right, left, front, or general upstream applications.\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 the threaded mounting point and connector orientation against the original part.\u003c\/li\u003e\n\u003cli\u003eClear diagnostic trouble codes after installation and confirm proper ECU feedback during a road test.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products manufactures engine management sensors as OE replacement parts for global vehicle applications and produces this sensor to the specified fitment and feedback requirements of the listed vehicles.\u003c\/p\u003e","brand":"Walker","offers":[{"title":"Default Title","offer_id":51870222942389,"sku":"DKHD-350-64073","price":119.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/O2_35064073_Fro.jpg?v=1774892231","url":"https:\/\/www.partcatalog.com\/products\/walker-350-64073-oxygen-sensor","provider":"PartCatalog","version":"1.0","type":"link"}
