Part number 250-54114 is built for the specified fitment position and provides the diagnostic feedback the ECU expects from the upstream sensor location. This matters on vehicles such as the 2014 Acura ILX, 2002-2006 Toyota Camry, and 2002-2003 Lexus ES300, where accurate upstream sensor input supports proper air-fuel control and emissions monitoring. The Walker Products OE line is backed by the company’s long-running experience in engine management components and ISO 9001\/TS 16949-certified manufacturing practices.\u003c\/p\u003e\u003cp\u003eThis part cross-references Walker Products OE 250-54114 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 performance\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy caused by incorrect exhaust feedback\u003c\/li\u003e\n\u003cli\u003eRough engine operation from inaccurate air-fuel correction\u003c\/li\u003e\n\u003cli\u003eElevated exhaust emissions from a failing heated 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\u003c\/h2\u003e\u003cp\u003eInstall this sensor in the listed upstream position only. Confirm connector shape, wire count, thread diameter, and harness length before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect signal quality. For best results, verify the vehicle’s fault codes and sensor location before replacing the part.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker Products OE manufactures this oxygen sensor as an OE-style replacement for the specified application and fitment position.
