Walker 350-341016 Oxygen Sensor - Downstream Front or Downstream Rear

Walker 350-341016 Oxygen Sensor for Lincoln MKT

Walker 350-341016 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Lincoln MKT applications. It is designed for downstream monitoring, helping the ECU read exhaust oxygen levels after the catalyst so the vehicle can maintain proper fuel control and emissions feedback.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered for application-specific fitment. The 350-341016 follows that approach with the correct mounting style, connector design, and wire configuration for the listed vehicle positions.

Key Features

• Heated oxygen sensor for downstream exhaust monitoring
• Specific fit application for select 2013-2015 Lincoln MKT positions
• Threaded mounting type with 18.0 mm thread diameter
• 4-wire design with 20-gauge wiring
• Radiused polygon female connector for vehicle-specific connection
• Wiring harness length: 28.54 in.; overall length: 31.49 in.

Detailed Description

Walker Products 350-341016 is engineered for direct replacement in downstream rear, downstream front, and downstream right locations on the Lincoln MKT, depending on model year and configuration. This oxygen sensor provides the ECU with the exhaust feedback needed to monitor catalyst performance and support accurate engine management. For shoppers searching for a Lincoln MKT downstream oxygen sensor, post-cat oxygen sensor, or Walker 350-341016 replacement, this part is built around the listed application details rather than a universal design.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Vehicle Fitment

• Fits 2015 Lincoln MKT, downstream rear.
• Fits 2015 Lincoln MKT, downstream front.
• Fits 2014 Lincoln MKT, downstream rear.
• Fits 2014 Lincoln MKT, downstream front.
• Fits 2013 Lincoln MKT, downstream right.

What It Helps Address

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

Installation Notes and Tips

Confirm the sensor position before ordering, since this part is listed for specific downstream locations on the Lincoln MKT. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, and verify the threaded mounting point is clean and undamaged. Because fitment varies by year and position, match the vehicle application to the exact downstream rear, downstream front, or downstream right listing.

Quality Assurance

Walker Products has produced engine management components since 1946 and operates as an Automotive ISO9001/TS 16949 certified company. The 350-341016 is manufactured as an application-specific replacement to support the diagnostic feedback expected by the ECU.
