Delphi ES20083 Oxygen Sensor for Rear Applications

The Delphi ES20083 oxygen sensor is a heated, 4-wire replacement built for rear sensor locations on select Mitsubishi, Chrysler, and Dodge vehicles. It uses a square connector and 18 x 1.5 mm thread size, with an overall length of 755.0 for application-specific routing.

Key Features

  • Heated oxygen sensor for rear, rear left, and rear right positions
  • 4-wire design with square connector shape
  • 18 x 1.5 mm thread size
  • Overall length: 755.0
  • Includes oxygen sensor and instruction sheet

Application Details

Compatible with rear oxygen sensor applications on 1995-2012 Mitsubishi Eclipse, Mitsubishi Galant, Mitsubishi Montero, Chrysler Sebring, and Dodge Stratus, depending on engine and emission configuration. This part also cross-references DENSO Auto Parts 234-4656 for the same application.

Use Delphi ES20083 when replacing a rear oxygen sensor on vehicles such as the Mitsubishi Eclipse, Mitsubishi Galant, and Chrysler Sebring where the original sensor uses a heated 4-wire layout and square connector. The Delphi ES20083 is also listed for rear left and rear right positions on select Dodge Stratus and Mitsubishi Eclipse applications.

What It Helps Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel ratio readings from a worn rear sensor
  • Slow sensor response caused by age or contamination
  • Emission test failures tied to rear sensor output
  • Driveability issues linked to inaccurate exhaust feedback

Installation Notes and Tips

Confirm the exact position on your vehicle before ordering, since this sensor is listed for rear, rear left, and rear right locations. Match the connector shape, wire count, thread size, and overall length to the original part, and verify California emission system notes where shown in the fitment data. For best results, compare the old sensor to the new unit before installation.

Quality Assurance

Delphi draws on more than 100 years of OE experience and supplier knowledge from top automakers, with OE-based engineering principles carried into its aftermarket parts.
