Product Details

Walker Products 350-34679 is part of the Walker Products Aftermarket engine management line, which focuses on replacement sensors built for vehicle-specific fitment and ECU feedback requirements. This oxygen sensor is intended for center-position use on select Volvo XC60, XC70, S80, and V70 models, including 2010-2015 Volvo XC60, 2010-2015 Volvo XC70, 2010-2014 Volvo S80, and 2010 Volvo V70. The heated design helps the sensor reach operating temperature quickly so the engine control system can monitor exhaust conditions and adjust fueling as needed.

This part number, 350-34679, is a direct replacement option for drivers addressing sensor-related fault codes or drivability concerns on the listed Volvo applications. Walker Products has supplied engine management components since 1946 and manufactures this sensor to application-specific dimensions and connector requirements.

What It Can Help Resolve

• Check engine or MIL illumination tied to oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation related to incorrect air-fuel readings
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes for the affected sensor circuit

Installation Notes

Verify the connector shape, thread diameter, harness length, and center-position fitment before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since damaged wiring can shorten sensor life and affect ECU feedback. Confirm the vehicle application by year, make, model, and position before replacing the original unit.
