• Heated sensor design for faster operating response
• 4-wire configuration with threaded mounting
• 10.2500-inch wiring harness length
• 18.000 thread diameter

Detailed Description

NTK 22137 is part of the Direct Fit Oxygen Sensor line, which focuses on application-specific replacement sensors with OE-style fit, form, and function. NTK draws on its background as a major original equipment oxygen sensor supplier and uses controlled ceramic technology from raw material through finished production. This sensor is built to meet or exceed OE specifications through manufacturing and testing practices aimed at consistent quality and reliability. It fits 2011-2012 Ford Fusion, upstream right and upstream left, and 2011-2012 Lincoln MKZ, upstream right and upstream left. This part cross-references DENSO Auto Parts 234-4492 and Gates 18054 for the same application.

Common Uses

• Restoring accurate exhaust oxygen feedback
• Replacing a worn or failed heated oxygen sensor
• Addressing check engine light conditions related to sensor performance
• Correcting slow or inconsistent sensor response
• Maintaining proper air-fuel control in the exhaust system

Installation Notes

Verify the connector, thread diameter, harness length, and sensor position before installation. This sensor uses a threaded mounting style and a specific-fit design, so matching the application details is important for proper installation on Ford Fusion and Lincoln MKZ vehicles.

Quality Assurance

NTK tests oxygen sensors during manufacturing to support quality and reliability that meet or exceed OE specifications. The brand is part of the NGK family of products and is recognized for OE oxygen sensor manufacturing and application coverage.
