Walker Oxygen Sensor for Saab and Volvo

Walker Products Aftermarket oxygen sensor 350-34674 is a heated, specific-fit replacement built for downstream applications on select Saab 9-5, Saab 9-3, and Volvo S80 models. It is engineered to deliver the ECU feedback needed for proper fuel control and emissions monitoring.

Key Features

  • Heated oxygen sensor for faster operating response
  • Specific-fit design for the listed downstream applications
  • 4-wire configuration with male connector
  • Threaded mounting type with 18.0 mm thread diameter
  • Wiring harness length: 36.93 in.; overall length: 40.47 in.
  • Radiused polygon connector shape for application-specific fitment

Application Details

Walker Products Aftermarket focuses on OE-style engine management and oxygen/air-fuel sensors for exact vehicle applications. Part number 350-34674 is made for downstream placement and is listed for 2000-2009 Saab 9-5, 2000-2003 Saab 9-3, and select 2000-2002 Volvo S80 downstream positions, including cylinder-bank specific configurations noted for those vehicles. This part cross-references no additional part numbers in the provided data.

What It Helps Address

  • Check engine light related to downstream oxygen sensor faults
  • Poor fuel economy caused by inaccurate exhaust feedback
  • Rough engine operation from incorrect air-fuel correction
  • Elevated exhaust emissions from a failing sensor signal
  • Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Confirm the vehicle’s downstream sensor location, connector style, and thread size before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect signal quality. Verify the ECU fault code and application notes for the exact Saab 9-5, Saab 9-3, or Volvo S80 configuration before replacement.

Quality Assurance

Walker Products has produced engine management components since 1946 and operates as an Automotive ISO 9001 / TS 16949 certified company. The 350-34674 oxygen sensor is built as an OE-replacement style part for the specified application and fitment position.
