Walker 350-34369 Oxygen Sensor - Downstream or Upstream

Walker Oxygen Sensor for Hyundai Applications

Walker Products part 350-34369 is a heated oxygen sensor built as a specific-fit OE replacement for select Hyundai vehicles. It is engineered to deliver the diagnostic feedback the ECU expects, helping maintain proper fuel control and emissions monitoring on the covered applications.

Key Features

• Heated oxygen sensor with a specific-fit design
• 4-wire configuration with 20-gauge wiring
• Threaded mounting style with 18.0 mm thread diameter
• Radiused polygon male connector for application-specific fitment
• 11.73 in. wiring harness length and 15.28 in. overall length
• Walker Products Aftermarket engine management sensor line

Walker Products Aftermarket Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for a wide range of vehicles. Part number 350-34369 is built for the specified position and application so the sensor output aligns with the vehicle’s onboard diagnostics. For Hyundai Accent, Hyundai Elantra, and Hyundai Tiburon coverage, this sensor supports the factory-style feedback the ECU uses to monitor mixture and emissions performance.

Vehicle Fitment

• Fits 1995 Hyundai Accent, downstream.
• Fits 1996 Hyundai Accent, upstream and downstream.
• Fits 1997 Hyundai Accent, upstream and downstream.
• Fits 1996-1997 Hyundai Elantra, upstream.
• Fits 1997 Hyundai Tiburon, upstream.

What It Helps Address

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

Installation Notes

Confirm the sensor position before installation, since this part is listed for both upstream and downstream locations depending on the vehicle. Inspect the sensor, wiring harness, and connector for physical damage before replacement, and verify the threaded mounting point and connector style match the original unit. For 1997 Hyundai Accent applications, note the California and non-California ESV coverage shown in the fitment data.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and operates under Automotive ISO 9001/TS 16949 certification. Part number 350-34369 is manufactured for the specified application and position to support proper ECU feedback on the covered Hyundai models.
