NTK 23179 Oxygen Sensor

NTK Direct Fit Oxygen Sensor 23179

NTK Oxygen Sensor 23179 is a direct-fit, heated narrow-band replacement built for precise air-fuel feedback and OE-style electrical performance. It is used on a wide range of Chrysler, Dodge, Jeep, and Plymouth applications, including Chrysler 300M, Dodge Intrepid, and Jeep Cherokee fitments.

Key Features

• Direct fit oxygen sensor for specific vehicle applications
• Heated narrow-band design with switching zirconia technology
• 4-wire configuration with circular female connector
• Metric M18 x 1.5 thread size and 7/8 in. (22 mm) hex/wrench size
• 18.00 in. wiring harness length
• Standard replacement grade for emission control service
• OE-style sensor support from NTK, a major OEM oxygen sensor manufacturer

Product Details

NTK 23179 is part of the Direct Fit Oxygen Sensor line, which focuses on OE application coverage and sensor technology matched to the vehicle’s original configuration. As a heated narrow-band sensor, it provides closed-loop feedback to the ECU so the engine can maintain the correct air-fuel ratio and the OBDII system can monitor fuel delivery and catalytic converter efficiency. This part cross-references Bosch (e.g., 13100, 13138) for the same application.

Compatible vehicle coverage includes Fits 1999-2001 Chrysler 300M, Upstream Right; Fits 2002-2004 Chrysler 300M, Downstream Right; Fits 1996-2001 Chrysler Concorde, Upstream Right; Fits 2002-2004 Chrysler Concorde, Downstream Right; Fits 1996-2001 Chrysler Intrepid, Upstream Right; Fits 2002-2004 Chrysler Intrepid, Downstream Right; Fits 1997-2001 Dodge Ram 1500, Upstream Right; Fits 1997-2001 Dodge Ram 2500, Upstream Right; Fits 1997-2001 Dodge Ram 3500, Upstream Right; Fits 1997-2000 Jeep Cherokee, Upstream; Fits 1996-1998 Jeep Grand Cherokee, Upstream; Fits 1999-2000 Jeep Grand Cherokee, Downstream; Fits 1997-2000 Jeep Wrangler, Upstream.

What It Helps Address

• Check engine light caused by oxygen sensor signal faults
• Incorrect air-fuel ratio readings at the ECU
• Poor fuel economy related to aging sensor response
• Emissions test failures tied to sensor performance
• Catalytic converter monitoring issues reported by OBDII

Installation Notes and Tips

Verify the connector shape, wire count, thread size, and sensor position before installation. NTK 23179 uses a 4-wire, bullet-terminal, female circular connector with M18 x 1.5 threads, so it should be matched to the original sensor location and harness routing. Confirm whether your vehicle calls for upstream, downstream, left, or right placement, especially on Chrysler, Dodge, and Jeep applications.

Quality Assurance

NTK is a long-standing OEM oxygen sensor supplier with in-house ceramic technology used from raw material through finished sensor production. That manufacturing control supports consistent sensor construction and OE application coverage across the Direct Fit Oxygen Sensor line.
