Direct-Fit Oxygen Sensor

NTK Direct Fit Oxygen Sensor 22140 is a specific-fit heated oxygen sensor built for direct replacement applications. It is engineered for threaded mounting and uses a 4-wire design with a 31.5-inch harness for proper routing.

Compatible with Lincoln MKT applications, this sensor supports downstream left and downstream right positions on the listed vehicles. The NTK 22140 is part of the Direct Fit Oxygen Sensor line, which focuses on application-specific coverage and OE-style fit, form, and function.

Key Features

  • Specific-fit oxygen sensor for direct replacement use
  • Heated sensor design for faster operating response
  • 4-wire configuration with 31.5-inch wiring harness
  • Threaded mounting with 18.000 mm thread diameter
  • Part of NTK Direct Fit Oxygen Sensor coverage

Detailed Description

NTK 22140 is an emission control oxygen sensor designed for exact application coverage rather than universal use. It is a heated, threaded sensor with a 4-wire layout, making it suitable for vehicles that require a direct-fit replacement with the correct connector and harness length. This part cross-references DENSO Auto Parts 234-4936 and DE9Z9G444A for the same application.

For Lincoln MKT models, this sensor is listed for downstream left and downstream right positions on 2013-2015 vehicles, including heavy duty chassis and hearse configurations shown in the fitment data. If you are replacing a worn or faulty oxygen sensor on a Lincoln MKT, the NTK 22140 provides the application-specific design expected from an OE-focused emission control component.

What It Is Used For

  • Replacing a failed oxygen sensor that triggers emissions-related fault codes
  • Restoring proper exhaust gas monitoring in the emission control system
  • Addressing drivability issues caused by inaccurate sensor readings
  • Correcting heater circuit or sensor response problems
  • Maintaining proper feedback for engine management on compatible Lincoln MKT applications

Installation Notes and Tips

Verify the downstream left or downstream right position before ordering, since the fitment data lists both locations for the Lincoln MKT. Confirm the threaded mounting style, 4-wire configuration, and harness length against the original sensor before installation. Use the vehicle-specific fitment details to match the correct application for 2013-2015 Lincoln MKT models.

Quality Assurance

NTK is a major original equipment oxygen sensor supplier and tests these sensors during manufacturing to meet or exceed OE specifications. The Direct Fit Oxygen Sensor line is built around application coverage, fit accuracy, and reliable performance for emission control service.
