Delphi ES10671 Oxygen Sensor

Delphi ES10671 Oxygen Sensor Overview

The Delphi ES10671 is a front oxygen sensor built for specific import applications from the mid-1980s. It uses a non-heated, single-wire design with a round connector and 18 x 1.5 mm thread size, and it measures 570.0 mm overall length for the listed fitments.

Built from Delphi’s OE heritage and supplier experience, this oxygen sensor is a direct-fit replacement for vehicles such as the Audi Coupe, Subaru Standard, Volkswagen Cabriolet, Volkswagen Golf, Jaguar Vanden Plas, Jaguar XJ6, and Saab 900 in the years shown below.

Key Features

• Part number: ES10671
• Front oxygen sensor position
• Non-heated sensor type
• 1-wire configuration
• Round connector shape
• 18 x 1.5 mm thread size
• 570.0 mm overall length

Detailed Description

Delphi ES10671 is an emission control oxygen sensor engineered for front sensor locations on select 1985-1987 vehicles. It is listed for 1985-1987 Audi Coupe, 1985-1987 Subaru Standard, 1985-1987 Volkswagen Cabriolet, 1985-1987 Volkswagen Golf, 1985 Jaguar Vanden Plas, 1985 Jaguar XJ6, and 1985 Saab 900. The ES10671 part number is also referenced across multiple aftermarket catalogs for the same application.

This sensor supports accurate exhaust feedback on older engine management systems that use a non-heated, single-wire O2 sensor. Delphi’s OE background is reflected in the fit, connector style, and thread specification used for these applications.

This part cross-references Bosch (e.g., 12046) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings at the front sensor location
• Rough idle or drivability issues tied to exhaust feedback
• Failed emissions inspection caused by a worn sensor
• Slow or inaccurate sensor response on older fuel-injected systems

Installation Notes and Tips

• Verify the vehicle uses a front, non-heated oxygen sensor before ordering.
• Confirm the 18 x 1.5 mm thread size and 570.0 mm overall length match the original part.
• Check connector shape and wire count against the existing sensor harness.
• Inspect the exhaust bung threads before installation to ensure proper seating.
• Use the included instruction sheet for application-specific guidance.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed over decades of original equipment service. That OE heritage is applied to the ES10671 oxygen sensor for consistent fit and application-specific performance.
