• Specific-fit design for the listed vehicle applications
• 4-wire configuration with female connector
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 15.74 in.
• Overall length: 18.70 in.
• Radiused polygon connector shape
• Walker Products Aftermarket line replacement

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as replacement parts for worldwide vehicle coverage. Part number 350-341014 is manufactured for the specified application and fitment position so the ECU receives the correct sensor feedback. This matters on newer vehicles that store fault codes when an oxygen sensor or related circuit is not performing correctly.

This oxygen sensor is listed for downstream positions across select Ford and Lincoln models, including Ford F-250 Super Duty, Ford F-350 Super Duty, and Lincoln Continental. It is also referenced in fitment for other Ford and Lincoln vehicles such as Explorer, Edge, Fusion, Taurus, Mustang, Transit, Transit-150, Transit-250, Transit-350, Transit-350 HD, Flex, MKT, MKX, MKZ, MKS, and E-350 Super Duty. Part number 350-341014 is intended for the exact sensor location shown in the fitment data.

This part cross-references no additional part numbers provided in the supplied data.

What It Helps Address

• Stored oxygen sensor fault codes in the ECU
• Rough engine operation caused by a failing downstream sensor
• Increased fuel consumption from incorrect exhaust feedback
• Higher exhaust emissions from inaccurate air-fuel monitoring
• Malfunction indicator light illumination related to sensor performance

Installation Notes and Tips

Verify the exact year, make, model, and sensor position before installation. Confirm the connector shape, wire count, thread diameter, and harness length against the original sensor. Inspect the sensor wiring harness and connector for physical damage, since damaged circuits can shorten sensor life and trigger fault codes. For Ford F-250 Super Duty and Ford F-350 Super Duty applications, confirm whether the vehicle uses the downstream left, downstream right, or rear/front position listed in the fitment table.

Quality Assurance

Walker Products states that its engine management and oxygen sensors are developed as OE replacement parts and manufactured under Automotive ISO9001/TS 16949 certification standards. Since 1946, the brand has supplied engine management sensors and fuel system components for vehicle service applications.
