Denso 234-4083 Oxygen Sensor - Downstream

Denso 234-4083 Oxygen Sensor for OE-Style Replacement

Denso 234-4083 is a heated, specific-fit oxygen sensor built for direct replacement in emission control systems. It is engineered for downstream use on select Chrysler Sebring, Dodge Avenger, and Mitsubishi Eclipse applications from 1995-1999, with OE-style fitment and a threaded mounting design.

Denso’s OE Style line focuses on exact replacement fit and consistent sensor performance. This oxygen sensor uses a 4-wire, female connector layout with a 25.20-inch wiring harness and a 0.708-inch thread diameter, making it a practical choice for drivers servicing a downstream sensor on the listed vehicles.

Key Features

• Heated oxygen sensor for downstream emission control service
• Specific-fit design for direct replacement
• 4-wire configuration with female connector
• 25.20-inch wiring harness length
• Threaded mounting type with 0.708-inch thread diameter
• OE Style replacement for select Chrysler, Dodge, and Mitsubishi applications

OE Style Design Details

The Denso OE Style product line is built around factory-style replacement requirements, with precision construction intended to match the original sensor location and connection style. Denso also incorporates an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management and long service life. This part number, 234-4083, is a direct-fit option for owners searching for a downstream oxygen sensor for 1995-1999 Chrysler Sebring, 1995-1999 Dodge Avenger, or 1995-1999 Mitsubishi Eclipse.

This part cross-references Bosch 13312 and NTK 23001 for the same application.

What This Oxygen Sensor Helps Address

• Check engine light related to downstream oxygen sensor performance
• Incorrect air-fuel feedback from a worn sensor
• Reduced fuel economy caused by inaccurate exhaust readings
• Rougher engine operation tied to emission sensor faults
• Failed emissions inspection due to sensor-related issues

Installation Notes and Tips

Verify the connector style, wire count, and threaded mounting location before installation. This sensor is listed for downstream placement only, so confirm the vehicle’s sensor position matches the application. For best results, inspect the harness routing and connector condition during replacement, especially on 1995-1999 Chrysler Sebring, Dodge Avenger, and Mitsubishi Eclipse models.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for replacement accuracy and consistent performance. The precision-built design supports first-time fitment on the listed applications, and the OE Style construction reflects Denso’s focus on factory-level replacement parts.
