Delphi ES20085 Rear Oxygen Sensor

Delphi ES20085 is a heated rear oxygen sensor built for precise exhaust monitoring on select Chrysler, Dodge, and Mitsubishi applications. It uses a 4-wire design, a square connector, and an 18 x 1.5 mm thread size for direct-fit replacement on listed vehicles.

Key Features

• Heated oxygen sensor for rear position exhaust feedback
• 4-wire configuration with square connector shape
• 18 x 1.5 mm thread size
• Overall length: 590.0
• Package contents: oxygen sensor and instruction sheet
• OE-focused engineering from Delphi, backed by 100 years of original equipment experience

Application Details

Compatible with rear sensor locations on 2001-2005 Chrysler Sebring, 2001-2005 Dodge Stratus, 2001-2005 Mitsubishi Eclipse, and 2001-2003 Mitsubishi Galant. It also fits 2000 Mitsubishi Eclipse, rear, with California Emission System, and 1999-2000 Mitsubishi Galant, rear, with California Emission System. Delphi ES20085 is a direct replacement choice for drivers searching for a rear oxygen sensor for Chrysler Sebring, Dodge Stratus, or Mitsubishi Eclipse and Galant applications.

This part cross-references Bosch 13796 and DENSO Auto Parts 234-4652 for the same application.

What It Helps Address

• Check engine light related to rear oxygen sensor performance
• Incorrect exhaust oxygen feedback to the engine control system
• Reduced emissions monitoring accuracy
• Fault codes tied to rear sensor circuit or response issues
• Driveability concerns caused by a worn or failing oxygen sensor

Installation Notes and Tips

Verify the rear sensor location, connector shape, and thread size before installation. Confirm vehicle year, make, model, and emission system details, especially on California Emission System applications. Use the included instruction sheet during installation and inspect the harness routing to avoid strain on the 4-wire lead.

Quality Assurance

Delphi builds this oxygen sensor using OE heritage and knowledge developed through long-term supplier experience with major automakers. That background supports consistent fitment and sensor construction for listed Chrysler, Dodge, and Mitsubishi rear applications.
