NTK 22542 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Direct Fit Oxygen Sensor Overview

NTK 22542 is a direct fit heated oxygen sensor for downstream applications on select Ford and Lincoln vehicles. It is built with a threaded mounting design and a 4-wire configuration for OE-style replacement where exact fitment matters.

Compatible With Ford Bronco Sport, Explorer, Maverick, Escape, Edge, Fusion, Focus, Taurus, Special Service Police Sedan, GT, and Lincoln Corsair, MKZ, Nautilus, MKC, and MKT in downstream positions. This part number 22542 is also listed for select downstream right and downstream left applications on the Ford GT.

• Heated oxygen sensor design for faster operating response.
• Specific-fit replacement for direct installation on listed applications.
• Threaded mounting type with 18 mm thread diameter.
• 29.5-inch wiring harness length for application-specific routing.
• OE-equivalent design language in fitment notes for matched replacement use.

Application Details

NTK 22542 is intended for downstream exhaust monitoring on the listed Ford and Lincoln models. The sensor supports emissions system feedback after the catalytic converter, helping maintain proper engine management and diagnostic performance on vehicles such as the Ford Explorer, Ford Escape, and Lincoln Corsair. NTK positions this oxygen sensor line around OE-style fit, form, and function, with manufacturing controls focused on quality and reliability.

Common Issues It Can Address

• Check engine light related to downstream oxygen sensor faults.
• Incorrect exhaust oxygen readings reported to the engine control system.
• Emissions monitor failures tied to sensor response or signal quality.
• Connector or harness mismatch when replacing a specific-fit sensor.
• Fitment problems from using a universal sensor in an OE-specific application.

Installation Notes

Verify the vehicle’s year, model, and downstream position before ordering. Confirm the threaded mounting style, 4-wire layout, and harness length against the original sensor. For 2016 Ford Edge, 2016 Ford Special Service Police Sedan, and 2016 Ford Taurus applications, review the listed build-date notes before installation.

Quality Assurance

NTK is part of the NGK family of products and is recognized as a major original equipment oxygen sensor supplier. This oxygen sensor is extensively tested during manufacturing to meet or exceed OE specifications. This part cross-references Ford and Lincoln OE numbers (e.g., F1FZ9G444A, FB5Z9G444A) for the same application.
