NTK 22009 Oxygen Sensor

Direct Fit Oxygen Sensor for Ford, Mazda, Mercury

NTK 22009 is a direct fit heated oxygen sensor built for specific downstream applications on select Ford, Mazda, Lincoln, and Mercury vehicles. It uses a 4-wire, threaded design with an 18-inch wiring harness for OE-style replacement on the listed positions.

Key Features

• Heated oxygen sensor with specific fitment for direct replacement
• 4-wire configuration with 18-inch wiring harness
• Threaded mounting type with 18 mm thread diameter
• Built for downstream rear, downstream, and downstream right locations
• NTK Direct Fit Oxygen Sensor line focuses on OE application coverage and form-fit-function matching

Product Details

NTK part number 22009 is part of the Direct Fit Oxygen Sensor line, which is engineered for specific vehicle applications rather than universal use. NTK draws on its role as a major OE oxygen sensor supplier and uses controlled ceramic manufacturing and extensive production testing to support consistent sensor performance. This oxygen sensor is listed for downstream positions on vehicles such as the Ford Escape, Ford Fusion, Ford Taurus, Mazda Tribute, Mercury Mariner, Mercury Milan, Lincoln MKS, and Lincoln MKT. This part cross-references Bosch (e.g., 15718, 15719) for the same application.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Fault codes tied to downstream sensor response
• Incorrect air-fuel feedback from a worn heated O2 sensor
• Emissions test failures caused by sensor degradation
• Driveability issues linked to inaccurate exhaust oxygen readings

Installation Notes and Tips

Verify the sensor position before ordering, since this part is listed for downstream rear, downstream, and downstream right locations depending on application. Confirm the 4-wire connector style, threaded mounting, and 18 mm thread diameter against the original sensor on your Ford Escape, Mazda Tribute, or Mercury Mariner application. Use the vehicle-specific fitment notes for model-year and position matching, including B1S2 and B2S2 references where shown.

Quality Assurance

NTK manufactures oxygen sensors with OE-level application coverage and tests them during production to help ensure quality and reliability that meet or exceed original equipment specifications. The Direct Fit Oxygen Sensor line is built to support accurate replacement on the listed Ford, Mazda, Lincoln, and Mercury applications.
