NTK 23141 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Direct-Fit Oxygen Sensor for OE Replacement

NTK 23141 is a direct-fit heated oxygen sensor built for specific downstream applications on select Jeep and Dodge vehicles. It uses a 4-wire, threaded design with an 18 mm thread diameter and an 18-inch wiring harness length for OE-style replacement on the listed vehicles.

As part of the NTK Direct Fit Oxygen Sensor line, this sensor reflects NTK’s focus on original-equipment coverage, precise ceramic control, and application-specific fitment for import and domestic emissions systems.

Key Features

• Direct-fit oxygen sensor for specific downstream applications
• Heated sensor design for emissions system feedback
• 4-wire configuration with threaded mounting
• 18 mm thread diameter and 18-inch harness length
• OE-style replacement for select Jeep Wrangler, Jeep TJ, Dodge Dakota, Dodge Durango, Dodge Ram 1500, Jeep Grand Cherokee, and Jeep Liberty applications

Detailed Description

NTK part number 23141 is engineered as a direct replacement oxygen sensor for downstream positions on select 2001-2004 Jeep and Dodge models. Confirmed applications include 2001-2004 Jeep TJ and Wrangler, 2001-2003 Jeep Grand Cherokee, 2002-2003 Jeep Liberty, 2001-2003 Dodge Durango, 2001-2003 Dodge Dakota, and 2003 Dodge Ram 1500, with position-specific coverage for downstream, downstream left, and downstream right locations where listed. This part cross-references Bosch 13687 for the same application.

NTK manufactures oxygen sensors with OE application focus and extensive production testing to support fit, form, and function. For buyers searching for a downstream oxygen sensor for Jeep Wrangler 2001-2004, a Jeep TJ downstream O2 sensor, or a Dodge Dakota downstream oxygen sensor, NTK 23141 provides a direct-fit replacement path that matches the listed vehicle and position requirements.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a failing downstream sensor
• Emissions test failures tied to sensor response issues
• Rough or inconsistent engine management data from a worn sensor
• Replacement needs for OE-style downstream sensor service

Installation Notes and Tips

Verify the vehicle year, make, model, engine configuration, emissions package, and sensor position before ordering. This sensor is listed for downstream use only on the applications shown, including downstream left and downstream right where specified. Match the 4-wire connector, threaded mounting style, and 18 mm thread diameter to the original sensor before installation.

For best results, inspect the harness routing and connector condition during replacement. Use the fitment notes to confirm whether your vehicle requires the downstream, downstream left, or downstream right location.

Quality Assurance

NTK is a major original-equipment oxygen sensor manufacturer, and this Direct Fit Oxygen Sensor line is manufactured and tested to meet or exceed OE specifications for the listed applications. The brand’s ceramics expertise and OE application focus support consistent sensor performance and reliable fitment.
