Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for worldwide vehicle coverage. Part number 350-33057 is built for upstream placement and is listed for 1994-1995 Hyundai Scoupe, upstream, including Bank 1 Sensor 1 applications. This Walker oxygen sensor supports the diagnostic feedback the ECU uses to manage air-fuel ratio, emissions performance, and fault detection.

Walker Products has supplied engine management and fuel system components since 1946 and manufactures to automotive ISO 9001/TS 16949 standards. The 350-33057 is a direct-fit oxygen sensor for Hyundai Scoupe owners addressing an upstream sensor replacement on the correct exhaust location.

Common Issues This Sensor Can Help Address

• Check engine light related to upstream oxygen sensor faults
• Poor engine performance caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel control
• Higher exhaust emissions from a failing oxygen sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Fits 1994-1995 Hyundai Scoupe, upstream. Confirm the connector shape, wire count, thread diameter, and mounting position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect ECU feedback. Verify the vehicle’s fault code and sensor location before replacing the part.
