Product Details

NTK Direct Fit Oxygen Sensor 22015 is part of the NTK Direct Fit Oxygen Sensor line, which focuses on application-specific replacement sensors for import and domestic vehicles. NTK uses ceramic-based manufacturing expertise and OE application coverage to deliver sensors with consistent fit, form, and function. This oxygen sensor is built for Ford Focus and Ford Transit Connect models in upstream locations, including 2006-2013 Ford Focus and 2010-2013 Ford Transit Connect applications listed below. This part cross-references DENSO Auto Parts 234-4107 for the same application.

Vehicle Fitment

• Fits 2010-2013 Ford Transit Connect, Upstream — Bank 1 Sensor 1 Oxygen Sensor; Direct Fit Oxygen Sensor
• Fits 2008-2011 Ford Focus, Upstream — Bank 1 Sensor 1 Oxygen Sensor; Direct Fit Oxygen Sensor
• Fits 2007 Ford Focus, Upstream — Located in Manifold; B1S1; OE MFR: NTK; Direct Fit Oxygen Sensor
• Fits 2006 Ford Focus, Upstream — Located in Manifold; B1S1; w/o PZEV Evap. Emissions; OE MFR: NTK; Direct Fit Oxygen Sensor

Common Replacement Symptoms

• Check engine light related to oxygen sensor performance
• Rough idle or inconsistent air-fuel feedback
• Reduced fuel control from a failing upstream sensor
• Fault codes tied to Bank 1 Sensor 1 operation
• Delayed sensor response during closed-loop operation

Installation Notes

Install this sensor in the specified upstream position only and verify the connector, thread diameter, and harness length before installation. For Ford Focus and Ford Transit Connect service, confirm the exact model year and emissions configuration, including the 2006 Focus note for vehicles without PZEV evaporative emissions. Use the listed OE-style application data to match the correct Bank 1 Sensor 1 location.

Quality Assurance

NTK manufactures oxygen sensors to meet or exceed OE specifications and tests them during production for quality and reliability. As the Sensor Specialist and a major OE oxygen sensor supplier, NTK supports direct replacement coverage for Ford Focus and Ford Transit Connect applications.
