NTK 23039 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

NTK Direct Fit Oxygen Sensor 23039

NTK 23039 is a direct fit heated oxygen sensor built for specific upstream applications on select Chrysler, Dodge, and Plymouth vehicles. It uses a 4-wire, threaded design with an 18 mm thread diameter and an 11.75 in. wiring harness length for OE-style replacement in the correct location.

Key Features

• Specific-fit heated oxygen sensor for direct replacement
• 4-wire configuration for upstream air-fuel monitoring
• Threaded mounting with 18 mm thread diameter
• 11.75 in. wiring harness length
• OE-style fit, form, and function for import and domestic applications
• Cross-references Bosch 15705 and DENSO Auto Parts 234-4077 for the same application

What It Helps Address

• Check engine light concerns related to upstream oxygen sensor performance
• Incorrect air-fuel ratio feedback from a worn sensor
• Slow sensor response during closed-loop operation
• Driveability issues tied to inaccurate exhaust oxygen readings
• Replacement needs for OE-style service on Chrysler, Dodge, and Plymouth models

Installation Notes

Confirm the connector style, wire count, and upstream position before installation. This NTK 23039 sensor uses a threaded mount and a 4-wire heated design, so the replacement should match the vehicle’s original sensor configuration. Verify the application by year, make, model, and position before ordering, especially on vehicles with left and right upstream sensor locations.
