OE Style Design and Fitment

The Denso OE Style line focuses on direct replacement parts that match original equipment fit and function. Part number 234-4079 is precision built for first-time fit on listed Chrysler Sebring and Cirrus applications, Dodge Stratus, Ram, Dakota, Viper, and Jeep Grand Cherokee, TJ, and Wrangler models. This part cross-references Bosch 13280 and NTK 23014 for the same application.

Compatible vehicle coverage includes Fits 2004 Chrysler Sebring, downstream; Fits 2004 Dodge Stratus, downstream; Fits 2000 Jeep Wrangler, downstream; and Fits 1996-2001 Dodge Ram 2500, downstream. Additional coverage includes Fits 1998-2000 Dodge Stratus, upstream and Fits 1999-2000 Jeep Grand Cherokee, downstream.

What This Oxygen Sensor Helps Address

  • Check engine light concerns related to oxygen sensor performance
  • Incorrect air-fuel mixture readings
  • Reduced fuel economy caused by a worn sensor
  • Slow sensor response during closed-loop operation
  • Emissions test failures tied to sensor degradation

Installation Notes

Verify the sensor position, connector style, and thread size before installation. This is a specific-fit, heated oxygen sensor with a female connector and threaded mounting, so matching the listed application is important for proper routing and connection. Confirm whether your vehicle requires upstream, downstream, upstream right, or upstream front placement before ordering.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for consistent replacement quality and accurate fitment. The sensor’s protective trap layer is designed to help resist contamination that can shorten sensor life and affect engine performance.
