Walker 250-25180 Oxygen Sensor - Upstream Right

Overview

Walker OE Base Sensor 250-25180 is a specific-fit oxygen sensor built as a standard replacement for emissions monitoring. It uses a heated wide-band design with a threaded M18 x 1.5 mount, making it a direct match for applications that require precise exhaust feedback.

Compatible With Ford Bronco, Ford Ranger, and Ford F-53 Motorhome Chassis applications listed below, this sensor is identified by part number 250-25180 and uses a 5-wire layout with a D-shape female connector.

Key Features

• Heated wide-band oxygen sensor for accurate exhaust signal response.
• Specific-fit design with threaded mounting and metric M18 x 1.5 threads.
• 5-wire construction with blade terminals and a D-shape female connector.
• Standard replacement grade for emissions system service.
• 350 mm harness length with 20-gauge wiring.

Fitment Details

• Fits 2021-2025 Ford Bronco, Upstream Right, OE Base Sensor.
• Fits 2024-2025 Ford Ranger, Upstream Right, OE Base Sensor.
• Fits 2021-2022 Ford F-53 Motorhome Chassis, Upstream Right, OE Base Sensor.

What It Helps Address

• Faulty oxygen sensor readings that can trigger emissions-related trouble codes.
• Rough air-fuel control caused by a worn or slow-responding sensor.
• Reduced exhaust feedback accuracy in heated wide-band applications.
• Connector or thread mismatch during sensor replacement.

Installation Notes

Verify the upstream right location, connector shape, terminal count, and thread size before installation. The sensor uses a threaded mount and a 7/8 in. wrench size, so matching the exhaust bung and harness routing is important. Confirm the application by vehicle, model year, and OE Base Sensor requirement before ordering.

Quality Assurance

Walker OE Base Sensor parts are built as standard replacement emissions components for specific-fit applications. Part number 250-25180 should be matched to the listed Ford Bronco, Ford Ranger, and Ford F-53 Motorhome Chassis fitments for correct application coverage.
