If the original sensor has failed, the vehicle may show poor running behavior, higher fuel use, increased exhaust emissions, or a malfunction indicator light. For diagnosis, inspect the sensor, wiring harness, and connector for physical damage before replacement.\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\u003eRough engine operation caused by incorrect exhaust feedback\u003c\/li\u003e\n\u003cli\u003eIncreased fuel consumption from inaccurate air-fuel monitoring\u003c\/li\u003e\n\u003cli\u003eHigher exhaust emissions from a worn 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\u003eConfirm the exact position before installation: downstream rear, upstream, upstream rear, or upstream front, depending on the vehicle. This Walker 350-34302 oxygen sensor uses a threaded mount and application-specific connector, so match the original sensor layout, harness length, and connector orientation before replacement. For Hyundai Sonata, Hyundai XG350, and Kia Amanti fitments, verify emissions configuration and production date notes where listed.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products has manufactured engine management and oxygen\/air-fuel sensors since 1946 and operates as an Automotive ISO 9001\/TS 16949 certified company.
