Walker OE Oxygen Sensor for Genesis G80 and G90

Walker Products OE oxygen sensor 250-241282 is an OE-style replacement built for specific downstream positions on select Genesis vehicles. It is engineered to provide the ECU with the correct diagnostic feedback for emissions and fuel-control monitoring.

Key Features

• OE replacement oxygen sensor from Walker Products OE
• Built for the specified downstream left or downstream right application
• Supports ECU feedback for emissions system monitoring
• Designed for direct fitment on select Genesis G80 and Genesis G90 models
• Walker Products OE part number 250-241282

Detailed Description

Walker Products OE 250-241282 is an oxygen sensor developed as an original-equipment replacement for vehicles that require precise downstream sensor placement. On the Genesis G80 and Genesis G90, the sensor helps the engine management system monitor exhaust conditions and maintain proper diagnostic reporting. Walker Products has focused on application-specific fitment, so the sensor is matched to the required position and vehicle electronics for the listed models.

Walker Products OE is the brand line for application-specific engine management and oxygen/air-fuel sensors. This line is built around OE-style replacement needs, with attention to fitment position, connector application, and ECU feedback requirements. For buyers searching for a Genesis G80 downstream oxygen sensor or a Genesis G90 downstream oxygen sensor, part number 250-241282 is the listed OE replacement.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Fault codes stored in the ECU for downstream sensor circuits
• Poor engine operation caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect sensor readings
• Higher exhaust emissions from a failing oxygen sensor

Installation Notes and Tips

• Verify the exact position before installation: downstream left or downstream right.
• Inspect the sensor wiring harness and connector for damage before replacement.
• Check for stored ECU fault codes after installation and clear them as needed.
• Confirm vehicle application by year, model, and position before ordering.

Quality Assurance

Walker Products states that its engine management sensors are developed as OE replacements and manufactured under Automotive ISO 9001/TS 16949 quality systems. Part number 250-241282 is intended for the listed Genesis applications and positions, including Genesis G80 and Genesis G90 downstream sensor locations.
