Product Line Details

NTK Direct Fit Oxygen Sensor products are built around OE application coverage and precise sensor construction. As part of NTK’s oxygen sensor line, this part number 22114 reflects the brand’s focus on fit, form, and function for import and domestic vehicles, including Mazda 626 applications that require an upstream replacement sensor.

Detailed Description

NTK 22114 is an upstream oxygen sensor for the Mazda 626 that monitors exhaust oxygen content so the engine control system can adjust fuel delivery and emissions strategy. This direct fit sensor is designed for the 2001-2002 Mazda 626 upstream Bank 1 Sensor 1 position and the 2000 Mazda 626 upstream California emissions B1S1 application. If you are searching for an NTK 22114 oxygen sensor, Mazda 626 upstream oxygen sensor, or a direct fit replacement for part number 22114, this unit matches the listed OE-style application requirements.

This part cross-references Bosch 15278 and Delphi ES20121 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings
• Reduced fuel control accuracy
• Emissions test failures tied to upstream sensor faults
• Slow or inconsistent sensor response

Installation Notes and Tips

Verify the vehicle year, engine/emissions setup, and sensor position before ordering. This sensor is threaded and specific-fit, so confirm the upstream Bank 1 Sensor 1 location on the 2001-2002 Mazda 626 or the California emissions B1S1 setup on the 2000 Mazda 626. Inspect the connector routing and harness length before installation to ensure proper reach and secure placement away from heat sources.

Quality Assurance

NTK manufactures oxygen sensors with OE-level application coverage and extensive production testing to support consistent fit and reliable operation. The brand is recognized as a major original equipment oxygen sensor supplier, and this part is built to meet or exceed OE specifications for the listed Mazda 626 applications.
