Bosch 17487 Oxygen Sensor - Upstream or Upstream Right

Bosch Wideband OE Oxygen Sensor

Bosch 17487 is an Actual OE wideband air-fuel oxygen sensor built for precise upstream fuel-trim feedback. It delivers continuous lambda measurement for accurate air-fuel control on Ford and Lincoln applications, including Ford Edge, Mustang, F-150, and Explorer.

The Bosch Actual OE Oxygen Sensor line is built around OE development standards and wideband sensing technology used in modern engine management systems. Bosch pioneered the planar pump-cell design that became the standard for wideband A/F sensing, and this sensor carries that OE-focused engineering into the aftermarket.

• Wideband A/F oxygen sensor with continuous air-fuel ratio measurement
• Heated design for faster light-off and stable operation
• Specific-fit replacement with 5-wire harness and included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Oblong male connector, blade terminals, and 6 terminal quantity
• Metal housing with robust ceramic construction for thermal durability
• Bosch part number 17487 for direct catalog lookup

Detailed Product Overview

This Bosch 17487 oxygen sensor is designed for upstream placement where the engine control module relies on fast, accurate feedback to manage fuel delivery. Its wideband sensor type provides more detailed information than a traditional switching sensor, helping maintain proper mixture control during idle, acceleration, and load changes. The 12.4 in wiring harness length and 15.7 in overall length support OE-style routing on the listed Ford and Lincoln vehicles.

Compatible With 2015-2024 Ford Edge, upstream; 2015-2023 Ford Mustang, upstream; 2015-2020 Ford F-150, upstream right; 2016-2019 Ford Explorer, upstream; and additional listed Ford and Lincoln upstream applications. Bosch 17487 is also a direct search match for shoppers looking for an upstream right oxygen sensor for Ford F-150 or an upstream wideband O2 sensor for Ford Edge and Mustang.

Common Problems This Sensor Can Address

• Fault codes related to upstream oxygen sensor performance
• Unstable air-fuel ratio readings from a worn wideband sensor
• Rough idle or hesitation caused by inaccurate mixture feedback
• Reduced fuel economy from poor fuel-trim control
• Emissions test failures tied to sensor response issues

Installation Notes

Install as a specific-fit, threaded upstream sensor using the correct 18 mm oxygen sensor socket or hex tool. Verify connector shape, terminal count, and harness routing before installation, and confirm the sensor position matches the vehicle listing, including upstream right on the 2015-2020 Ford F-150 application. This part cross-references Denso (e.g., 234-9005) for the same application.

Quality Assurance

Bosch has more than five decades of OE sensor development experience, and this Actual OE Oxygen Sensor line is built to OE-proven standards for accuracy, durability, and consistent signal response. Bosch 17487 is engineered for modern engine management systems that depend on precise wideband feedback.
