Delphi ES10685 Oxygen Sensor - Front or Front Left

Delphi ES10685 Oxygen Sensor Overview

The Delphi ES10685 is a heated oxygen sensor built for precise exhaust monitoring in select Ford and Mazda applications. It uses a 3-wire design with a flat connector and 18 x 1.5 mm thread size, making it a direct-fit option for front and front left positions where listed.

Delphi draws on OE engineering experience and supplier knowledge developed over decades of original-equipment service. That background is reflected in the ES10685 oxygen sensor’s construction and application coverage for 1996-1997 Ford Probe, 1996-1997 Mazda 626, and 1996-1997 Mazda MX-6 front oxygen sensor locations.

Key Features

• Heated oxygen sensor for faster exhaust feedback
• 3-wire configuration with flat connector shape
• 18 x 1.5 mm thread size for listed applications
• Overall length: 290.0
• Includes oxygen sensor and instruction sheet
• Position-specific coverage for front and front left locations
• Delphi ES10685 direct-fit replacement for select Ford and Mazda vehicles

Detailed Description

The Delphi ES10685 oxygen sensor is engineered for vehicles that require accurate air-fuel ratio monitoring at the front of the exhaust system. By using a heated design, it reaches operating temperature more quickly than an unheated sensor, helping the engine control module receive timely feedback during warm-up and normal driving. This part number is listed for 1996-1997 Ford Probe front left, 1996-1997 Mazda 626 front left and front, and 1997 Mazda MX-6 front positions. This part cross-references Bosch 13284 and DENSO Auto Parts 234-3010 for the same application.

For buyers searching for a Delphi ES10685 oxygen sensor for Ford Probe front left or a Mazda 626 front oxygen sensor, this part provides the OE-style fit and connector layout needed for the specified applications. The flat connector and threaded mounting design support straightforward replacement when the original sensor matches the listed configuration.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle caused by incorrect exhaust feedback
• Reduced fuel economy from inaccurate air-fuel mixture control
• Slow sensor response during cold start operation
• Emissions test failures tied to front sensor faults

Installation Notes and Tips

Verify the vehicle’s exact position before ordering, since this sensor is listed for front and front left locations depending on application. Confirm the connector style, thread size, and overall length against the original part before installation. Use the application tab or vehicle service information to match the correct side and position for your Ford Probe, Mazda 626, or Mazda MX-6.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and knowledge developed through long-term original-equipment supply experience. The ES10685 is produced to support the fitment and performance expectations of the listed applications.
