It is engineered as an OE-style replacement to deliver the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions monitoring.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHeated oxygen sensor for downstream placement\u003c\/li\u003e\n\u003cli\u003eSpecific-fit design for the listed BMW and Mercedes-Benz applications\u003c\/li\u003e\n\u003cli\u003e4-wire configuration with a male radiused polygon connector\u003c\/li\u003e\n\u003cli\u003eThreaded mounting with 18.0 mm thread diameter\u003c\/li\u003e\n\u003cli\u003eWiring harness length: 17.24 in.; overall length: 20.79 in.\u003c\/li\u003e\n\u003cli\u003eWire gauge: 22\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eWalker Products OE line focuses on direct-replacement engine management components built for defined vehicle applications. Part number 250-24465 is designed for downstream oxygen sensor locations, including bank and rear positions where specified in the fitment data. For BMW M5, M6, Z4, 328i, 335i, 528i, X5, and related models, as well as Mercedes-Benz SL55 AMG, E500, C320, and others, this sensor supports the ECU’s emissions and fuel-trim monitoring strategy.\u003c\/p\u003e\u003cp\u003eWalker Products has supplied engine management and oxygen\/air-fuel sensors since 1946 and manufactures to ISO 9001\/TS 16949 standards. If a sensor fault is present, the vehicle may store ECU codes and show drivability or emissions-related symptoms. This part cross-references Bosch 17098 and Denso 234-9005 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCheck engine light related to downstream oxygen sensor performance\u003c\/li\u003e\n\u003cli\u003eFault codes stored in the ECU for sensor or emissions-system monitoring\u003c\/li\u003e\n\u003cli\u003ePoor fuel economy caused by inaccurate exhaust feedback\u003c\/li\u003e\n\u003cli\u003eRough engine operation tied to incorrect air-fuel correction\u003c\/li\u003e\n\u003cli\u003eElevated exhaust emissions from a failing 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 right, downstream left, downstream rear, or downstream, depending on the vehicle. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before replacement.
