Detailed Product Overview

Walker Products develops engine management and oxygen/air-fuel sensors as OE replacement parts for many vehicles worldwide. Part number 250-241318 is built for the exact application, fitment position, and diagnostic feedback requirements listed in the catalog data. The sensor is designed to communicate exhaust oxygen content to the ECU so the vehicle can maintain proper air-fuel control and emissions monitoring.

This part number 250-241318 is listed for multiple Jeep Wrangler, Jeep Grand Cherokee, Jeep Grand Cherokee L, Jeep Cherokee, Jeep Wagoneer, Ram 1500, Ram ProMaster, Chrysler 300, and Dodge Challenger/Charger applications. If you are replacing a failed upstream or downstream oxygen sensor, confirm the exact position before ordering to match the vehicle’s diagnostic system and connector layout.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Oxygen Sensor Helps Address

• Check engine light or MIL illumination related to oxygen sensor faults
• Poor engine performance caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for the affected sensor circuit
