Walker 350-64116 Oxygen Sensor - Upstream

Walker 350-64116 Upstream Oxygen Sensor

Walker Products 350-64116 is a heated upstream oxygen sensor built as a direct-fit OE replacement for select Volvo applications. It is engineered for accurate ECU feedback, helping maintain proper air-fuel control, emissions performance, and drivability.

Compatible With 2015-2018 Volvo S60, 2017-2018 Volvo S60 Cross Country, 2016-2018 Volvo V60, 2017-2018 Volvo V60 Cross Country, and 2015-2018 Volvo XC60 upstream positions. This part number, 350-64116, is designed for specific fitment and connector placement.

Key Features

• Heated oxygen sensor for upstream exhaust monitoring
• Specific-fit design for the listed Volvo models and positions
• 4-wire configuration with male connector
• 18.00 mm thread diameter
• 18.23 in. wiring harness length and 21.77 in. overall length
• 20-gauge wiring for application-specific electrical routing

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for a wide range of vehicles. The 350-64116 is built for upstream sensor locations, where it provides the feedback the ECU uses to manage fuel delivery and monitor exhaust performance. For Volvo S60, Volvo V60, and Volvo XC60 applications, this sensor supports accurate diagnostic reporting when the original unit is worn, contaminated, or electrically damaged.

This part cross-references common OE-style oxygen sensor applications for the same vehicle coverage. If the check engine light is on, fuel economy has dropped, or the engine is running rich or lean, the sensor circuit should be inspected along with the connector and harness.

What This Sensor Helps Address

• Check engine light related to upstream oxygen sensor performance
• Poor fuel economy from incorrect air-fuel feedback
• Rough running or hesitation caused by inaccurate exhaust readings
• Increased exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the oxygen sensor circuit

Installation Notes

Verify the vehicle’s year, model, and upstream sensor position before installation. Inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals before replacing the part. Confirm thread size and connector style match the original unit on the vehicle.

Quality Assurance

Walker Products has produced engine management components since 1946 and operates under Automotive ISO9001/TS 16949 certification. The 350-64116 is manufactured for the specified application and fitment position to support proper ECU feedback on the listed Volvo vehicles.
