Key Features

• Direct fit oxygen sensor for specific downstream applications
• Heated sensor design for faster operating response
• 4-wire construction with an 11.75 in. wiring harness length
• 18 mm threaded mounting type
• OE-style replacement from NTK, the original equipment oxygen sensor manufacturer
• Cross-references Bosch 13149 and Delphi ES20048 for the same application

Product Details

NTK Direct Fit Oxygen Sensor 23002 is built for downstream B1S2 locations on select 1996-1997 Chrysler Town & Country, Dodge Caravan, Dodge Grand Caravan, Plymouth Grand Voyager, and Plymouth Voyager models. It also covers 1997 Caravan, Grand Caravan, Grand Voyager, and Voyager applications that meet OEM standards. NTK uses ceramic manufacturing expertise and production testing to deliver a sensor that matches OE specifications for fit and electrical performance.

This part number 23002 is a practical replacement when servicing emissions and fuel-control systems on these Chrysler and Dodge vans. The direct-fit design helps maintain the original connector and mounting style, making it a focused choice for technicians and DIY repairs working on downstream oxygen sensor replacement.

Common Reasons to Replace

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a worn downstream sensor
• Emissions test failure tied to sensor response or signal quality
• Corrosion or damage at the original sensor body or wiring harness
• Restoring proper exhaust monitoring on Chrysler, Dodge, and Plymouth minivans

Installation Notes

Verify the vehicle’s year, model, and downstream B1S2 location before ordering. This oxygen sensor uses a threaded mounting type and a 4-wire heated design, so confirm connector routing and harness length during installation. For best results, inspect the exhaust threads and wiring path before removing the old sensor, and compare the original sensor configuration to NTK 23002 before final fitment.

Quality Assurance

NTK is a major original equipment oxygen sensor supplier and manufactures sensors to meet or exceed OE specifications. Each sensor is extensively tested during production to support reliable operation and consistent fitment on the listed Chrysler, Dodge, and Plymouth applications.
