Bosch 16224 Oxygen Sensor - Downstream

Bosch Actual OE Oxygen Sensor 16224

Bosch 16224 is a downstream narrow-band heated oxygen sensor built for specific Ford and Lincoln applications. It provides the air-fuel ratio feedback the ECU uses for closed-loop fuel control, helping maintain stable combustion and emissions performance.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band heated O2 sensor with threaded mounting
• Specific fit design for direct application matching
• 4-wire configuration with oblong female connector
• Wiring harness included for the listed applications
• 22 mm hex size and 18 mm thread diameter
• Metal housing with high-temperature-resistant construction

Product Details

Bosch 16224 uses a switching-type narrow-band design to send precise oxygen-content feedback to the engine control unit. Bosch developed this sensor family from its original OE oxygen sensor work and later planar narrowband designs, focusing on faster light-off, accurate lambda control, and quicker closed-loop operation. For drivers and technicians servicing a Ford Explorer downstream oxygen sensor, Ford Escape downstream oxygen sensor, or Lincoln Corsair downstream oxygen sensor, this part supports the factory-style signal response expected by the vehicle calibration.

This part cross-references Ford OE numbers F1FZ9G444H and FB5Z9G444C for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel trim readings caused by a worn downstream sensor
• Slow sensor response during closed-loop operation
• Emissions test failures tied to inaccurate exhaust feedback
• Rough combustion control from degraded sensor output

Installation Notes

Fits 2021-2025 Ford E-350 Super Duty, downstream; 2021-2024 Ford Bronco Sport, downstream; 2016-2024 Ford Explorer, downstream; 2020-2023 Lincoln Corsair, downstream; 2018-2022 Ford EcoSport, downstream; 2017-2022 Ford Escape, downstream; 2017-2022 Ford GT, downstream; 2017-2019 Lincoln MKC, downstream; 2016-2018 Ford Focus, downstream; 2016-2017 Ford Taurus, downstream; and 2016 Lincoln MKT, downstream.

Confirm connector shape, wire count, thread size, and downstream location before installation. Use the correct oxygen sensor socket and avoid contaminating the sensing element during handling. Verify the harness routing and connector lock engagement after installation.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development and aftermarket supply experience. The design uses ceramic sensing elements, controlled heater operation, and durable materials selected for thermal and vibration resistance in everyday service.
