Walker 350-34287 Oxygen Sensor - Downstream

Walker 350-34287 Oxygen Sensor for Hyundai Accent

Walker Products 350-34287 is a heated oxygen sensor built as a specific-fit OE replacement for select Hyundai Accent applications. It is designed for downstream Bank 1 Sensor 2 locations on listed 1997-1999 models, helping the ECU monitor exhaust feedback and maintain proper engine management.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific-fit design for listed Hyundai Accent applications
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for vehicle-specific connection
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 10.55 in.; overall length: 14.09 in.

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered as OE-style replacements for a wide range of vehicles. Part number 350-34287 is built for the specified fitment position and provides the diagnostic feedback expected by the ECU on downstream applications. For Hyundai Accent owners, this sensor is listed for 1997 models from 05/01/97 and for 1998-1999 models in downstream Bank 1 Sensor 2 positions.

This part cross-references no listed interchange numbers in the provided data. Walker Products 350-34287 is a direct-fit oxygen sensor choice for Hyundai Accent downstream service where the original sensor has failed or is reporting incorrect exhaust feedback.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust readings
• Rough engine operation from incorrect ECU feedback
• Higher exhaust emissions from a failing downstream sensor
• Stored fault codes tied to the affected sensor circuit

Installation Notes

Verify the vehicle’s build date and sensor position before ordering. This Walker 350-34287 oxygen sensor is threaded and vehicle-specific, so confirm the connector style, wire count, and downstream Bank 1 Sensor 2 location match the original part. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since damaged wiring can shorten sensor life and affect readings.

Quality Assurance

Walker Products manufactures engine management sensors under ISO 9001/TS 16949 quality systems and has supplied automotive components since 1946. The 350-34287 is engineered for the listed application and fitment position to deliver the diagnostic feedback required by the vehicle ECU.
