Delphi ES10289 Oxygen Sensor - Front or Rear

Delphi ES10289 Oxygen Sensor Overview

The Delphi ES10289 is a heated oxygen sensor built for emission control service on select Audi, Volkswagen, Saab, and Volvo applications. It uses a 3-wire design with square and round connector shapes, an 18 x 1.5 mm thread, and a 710.0 overall length for the listed front, rear, and upstream positions.

Built from Delphi’s OE heritage and supplier experience, this oxygen sensor is intended for direct replacement service where the original sensor matches the listed connector style and length. It is a fitment-based solution for vehicles such as the Audi A6, Audi 90, and Volkswagen Vanagon.

Detailed Description

Delphi ES10289 is engineered for vehicles that require a heated O2 sensor with the specified connector and length. The sensor supports air-fuel ratio feedback used by the engine control system to manage emissions and drivability. This part number, ES10289, is listed across multiple import applications, including 1996-1997 Audi A6, 1994-1998 Audi Cabriolet, and 1986-1991 Volkswagen Vanagon, along with select Saab 9000, Saab 900, and Volvo 740 and 745 models.

This part cross-references Bosch 13396 for the same application. Delphi ES10289 is also associated with OE-style replacement numbers used on Audi A6, Audi 100, and Audi 90 platforms where the 710 mm length is required.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect fuel trim readings from a worn sensor
• Failed emissions inspection caused by sensor degradation
• Rough idle or hesitation tied to inaccurate exhaust feedback
• Slow sensor response on heated oxygen sensor circuits

Installation Notes

• Verify the position listed for your vehicle before ordering; applications include front, rear, and upstream locations.
• Confirm the connector shape and 710.0 overall length match the original sensor.
• Check thread size and harness routing before installation.
• Use the vehicle application data to confirm the correct Audi A6, Audi 90, or Volkswagen Vanagon fitment.
• Follow the included instruction sheet and service manual procedures for removal and installation.

Quality Assurance
