OE Base Oxygen Sensor

Walker 250-241324 is a specific-fit oxygen sensor engineered as an OE-style replacement for the listed applications. It is a heated narrow-band sensor with a 4-wire design and square female connector for direct diagnostic feedback to the ECU.

Key Features

• Heated narrow-band oxygen sensor for precise exhaust feedback
• Specific-fit design for the listed applications
• 4-wire, 4-terminal construction with square female connector
• M18 x 1.5 thread size and 22 mm wrench size
• Walker OE Base Sensor line for application-specific replacement

Detailed Description

Walker 250-241324 is built for application-specific fitment and is part of Walker’s OE Base Sensor line. The sensor is manufactured for the exact position required by the vehicle and is intended to provide the feedback the ECU uses for fuel control and emissions monitoring. This part number is used across multiple Hyundai, Genesis, and Kia applications, including Fits 2022-2026 Hyundai Kona, upstream; Fits 2022-2026 Genesis GV70, downstream; and Fits 2021-2024 Kia Sorento, downstream. This part cross-references Walker Products (e.g., 250-241324) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel data
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for sensor-related issues

Installation Notes and Tips

Confirm the sensor position, connector style, thread size, and wire count before installation. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten service life. Use the listed fitment details to match the correct Hyundai, Genesis, or Kia application, including the proper upstream or downstream location.

Quality Assurance

Walker Products manufactures engine management sensors as OE replacement parts and operates under ISO 9001/TS 16949 certification. The OE Base Sensor line is built for application-specific fitment and ECU feedback requirements.
