Detailed Description

Walker Products OE 250-54116 is an emission control oxygen sensor engineered for vehicles that rely on accurate exhaust feedback to manage fuel delivery and emissions. As a heated sensor, it reaches operating temperature faster and supports the ECU with the signal needed for upstream monitoring. This matters on vehicles such as the Volvo S60, Volvo V60, and Volvo XC60, where the upstream sensor plays a direct role in air-fuel control and fault detection.

Walker Products develops engine management sensors as OE replacement parts for many global vehicle applications, with each part number built for a specific fitment position and diagnostic requirement. The Walker Products OE product line is aimed at restoring the correct sensor interface for the vehicle’s control system without changing the original application layout. Part number 250-54116 is a direct-fit oxygen sensor for the confirmed Volvo listings below.

Vehicle Fitment

• Fits 2015-2018 Volvo S60, upstream
• Fits 2017-2018 Volvo S60 Cross Country, upstream
• Fits 2016-2018 Volvo V60, upstream
• Fits 2017-2018 Volvo V60 Cross Country, upstream
• Fits 2017 Volvo XC60, upstream
• Fits 2015-2016 Volvo XC60, upstream, ULEV Spec
• Fits 2015-2016 Volvo XC60, upstream, Exc. ULEV Spec

What It Helps Address

• Check engine light related to upstream oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Higher exhaust emissions from a failing sensor signal
• Stored ECU fault codes tied to the oxygen sensor circuit

Installation Notes

Confirm the vehicle’s upstream sensor location before installation and verify connector style, thread diameter, and harness routing against the original part. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life and affect signal quality. For 2015-2016 Volvo XC60 applications, verify whether the vehicle is ULEV Spec or non-ULEV before ordering.

Quality Assurance

Walker Products OE sensors are developed as original-equipment replacement parts and manufactured under Automotive ISO9001/TS 16949 quality systems. The brand has supplied engine management and fuel system components since 1946, with a focus on application-specific fitment and ECU-relevant feedback.
