Walker 250-241247 Oxygen Sensor

OE Oxygen Sensor for Ford and Lincoln

Walker Products OE 250-241247 is an oxygen sensor engineered as an OE-style replacement for specific downstream positions on Ford and Lincoln vehicles. It provides the ECU with the exhaust feedback needed for fuel control and emissions monitoring on applications such as the Ford F-150, Ford Edge, Ford Explorer, Ford Mustang, and Lincoln Nautilus.

Key Features

• OE Base Sensor for downstream left, downstream right, downstream rear, and downstream front positions
• Application-specific fitment for the listed Ford and Lincoln models
• Supports diagnostic feedback required by the ECU
• Built for emissions-system service on vehicles with stored fault codes
• Walker Products OE line focused on original-equipment replacement coverage

Detailed Description

Walker Products OE 250-241247 is a direct-fit oxygen sensor for select 2018-2025 Ford and Lincoln applications. It is used in downstream locations where the ECU monitors exhaust efficiency and adjusts system operation based on sensor input. Fits 2018-2021 Ford F-150, downstream left; fits 2018-2021 Ford F-150, downstream right; fits 2019-2021 Ford Edge, downstream left; fits 2019-2021 Ford Edge, downstream right; fits 2020-2024 Lincoln Aviator, downstream right; and fits 2020-2023 Ford Explorer, downstream right. The Walker Products OE line is built around application-specific coverage, making it a practical choice when replacing a failed downstream oxygen sensor on Ford Transit, Mustang, Edge, Explorer, or Lincoln models.

This part cross-references no listed alternate part numbers in the provided data.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by incorrect exhaust feedback
• Elevated exhaust emissions from a failing downstream sensor
• Stored ECU fault codes tied to the affected sensor circuit
• Rough engine operation when emissions feedback is inaccurate

Installation Notes and Tips

Verify the exact position before ordering, since this part is listed for downstream left, downstream right, downstream rear, and downstream front applications depending on vehicle. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. If the vehicle has stored fault codes, confirm the related circuit and associated components before replacing the sensor.
