Part number 350-35158 is built as a standard replacement sensor with a heated wide-band design, 5-wire configuration, and a 6-terminal connector layout to match the required application. It is a fitment-based solution for 2024 Ford Expedition, 2024 Lincoln Navigator, and 2020 Cadillac CT6 applications, including upstream left and upstream right positions as listed. Walker 350-35158 is intended for drivers addressing sensor-related fault codes, poor engine performance, higher fuel use, or increased emissions caused by a failing oxygen sensor. This part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eWhat this part is used for\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a failed oxygen sensor that triggers a malfunction indicator light\u003c\/li\u003e\n\u003cli\u003eRestoring accurate exhaust feedback to the engine control system\u003c\/li\u003e\n\u003cli\u003eAddressing rough running or fuel economy loss linked to sensor faults\u003c\/li\u003e\n\u003cli\u003eCorrecting emissions issues caused by degraded sensor output\u003c\/li\u003e\n\u003cli\u003eReplacing damaged sensor wiring, connector, or harness-related components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes and tips\u003c\/h2\u003e\u003cp\u003eVerify the connector shape, terminal count, thread size, and sensor position before installation. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear before replacing the part. Confirm the listed fitment and position match the vehicle application exactly before service. Part number 350-35158 should be installed only where the application calls for this specific sensor configuration.\u003c\/p\u003e\u003ch2\u003eQuality assurance\u003c\/h2\u003e\u003cp\u003eWalker Products manufactures engine management and oxygen\/air-fuel sensors as OE replacement components and operates as an ISO 9001\/TS 16949 certified company.
