NTK 23093 Oxygen Sensor - Downstream

Direct Fit Oxygen Sensor for Import Applications

NTK 23093 is a direct fit heated oxygen sensor built for specific applications and threaded installation. It uses a 4-wire design with a 16.75-inch harness and an 18 mm thread diameter for a precise replacement match.

Compatible with Chrysler Cirrus, Dodge Stratus, and Plymouth Breeze downstream applications, this NTK oxygen sensor supports accurate exhaust feedback for emissions system operation. NTK 23093 is part of the Direct Fit Oxygen Sensor line, which focuses on application-specific coverage and OE-style fit, form, and function.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct replacement applications
• Threaded mounting with 18 mm thread diameter
• 4-wire configuration with 16.75-inch harness length
• Built for downstream emissions control applications

Detailed Description

NTK 23093 is engineered as a direct fit oxygen sensor for downstream use on select Chrysler, Dodge, and Plymouth models. The sensor’s heated design helps maintain signal performance as the exhaust system reaches operating temperature, while the threaded mount and specific-fit construction support straightforward replacement on the intended applications. This part number is also referenced as 23093 for catalog and search use.

NTK draws on its role as a major original equipment oxygen sensor supplier, and this sensor is manufactured and tested to meet OE-level specifications for fit and reliability. Cross-reference part numbers for the same application include Bosch 15704 and DENSO Auto Parts 234-4002.

What It Is Used For

• Replacing a worn or slow-responding downstream oxygen sensor
• Restoring proper exhaust gas feedback to the engine control system
• Addressing emissions-related fault codes tied to sensor performance
• Correcting drivability issues caused by inaccurate oxygen readings
• Maintaining emissions system operation on compatible vehicles

Installation Notes and Tips

Verify the downstream location, connector style, wire count, and thread size before installation. Use the vehicle’s service information to confirm the correct application for Chrysler Cirrus, Dodge Stratus, or Plymouth Breeze models. The threaded design is intended for direct replacement on the listed fitments, and the 16.75-inch harness should be routed to avoid heat and abrasion.

Quality Assurance

NTK tests these oxygen sensors during manufacturing to support OE-level quality and reliability. The brand’s OE supplier background and application-specific engineering are reflected in the Direct Fit Oxygen Sensor line, including part number 23093.
