NTK 22007 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor for Ford Focus

NTK 22007 is a direct fit heated oxygen sensor built for specific applications on the 2003-2007 Ford Focus. It is positioned downstream, below the heat shield after the catalyst, and uses a threaded mounting design for OE-style replacement service.

Key Features

• Direct fit oxygen sensor for specific vehicle applications
• Heated sensor design for faster operating response
• 4-wire configuration with a 15.75 in. wiring harness
• 18 mm thread diameter and threaded mounting type
• OE-style fit, form, and function for emission control service
• Compatible with 2003-2007 Ford Focus downstream applications

Product Details

NTK 22007 is part of the Direct Fit Oxygen Sensor line, created to streamline coverage while maintaining application-specific replacement accuracy. NTK uses ceramic manufacturing expertise and controlled production processes to deliver oxygen sensors with consistent construction and OE-level dimensional fit. For drivers and technicians servicing a Ford Focus, this downstream oxygen sensor supports exhaust monitoring after the catalyst and is built for the 2003-2007 Ford Focus, downstream position. The part number 22007 is also referenced in OE-style replacement searches for this application.

This part cross-references Bosch (e.g., 15645, 15802) for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor performance
• Fault codes tied to catalyst efficiency monitoring
• Rough or inconsistent emissions feedback from the exhaust system
• Failed emissions inspection caused by sensor malfunction
• Slow sensor response after catalyst service or exhaust repair

Installation Notes

Install in the downstream location specified for the 2003-2007 Ford Focus, below the heat shield after the catalyst. Confirm the 4-wire connector, 18 mm thread diameter, and harness length before installation. The threaded mounting design should be matched to the vehicle’s exhaust bung and routed to avoid heat damage or strain on the lead.

Quality Assurance

NTK is a major original equipment oxygen sensor manufacturer with extensive manufacturing testing to help ensure reliability and OE-spec performance. The NTK 22007 is built to meet or exceed original equipment expectations for fit and function in supported Ford Focus applications.
