  • Specific-fit design for select 1995-1997 Hyundai Accent, Elantra, and Tiburon applications
  • Threaded mounting with 18.0 mm thread diameter
  • 4-wire configuration with 20-gauge wiring
  • Radiused polygon male connector for application-specific fitment
  • Wiring harness length: 15.28 in.; overall length: 18.82 in.

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered for OE-style replacement use. Part number 350-34136 is built for specific vehicle fitment and downstream sensor locations, including Bank 1 Sensor 2 applications on select Hyundai models. For 1995-1997 Hyundai Accent, 1996-1997 Hyundai Elantra, and 1997 Hyundai Tiburon, this sensor supports the feedback the ECU uses to monitor exhaust conditions and adjust engine operation.

This part cross-references no listed interchange numbers in the provided data. Walker 350-34136 is a practical choice when replacing a failed downstream oxygen sensor on a Hyundai Accent, Hyundai Elantra, or Hyundai Tiburon with the matching application.

What It Helps Address

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

Installation Notes and Tips

Confirm the vehicle’s year, model, and downstream position before installation. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear, since damaged wiring can shorten sensor life and affect readings. Verify the threaded mounting location and connector style match the original part before replacement.

Quality Assurance

Walker Products states that its engine management and oxygen/air-fuel sensors are developed as OE replacement parts for worldwide vehicle applications. The company is ISO 9001/TS 16949 certified and has supplied engine management components since 1946.
