Delphi ES10005 Oxygen Sensor

Delphi ES10005 Oxygen Sensor Overview

The Delphi ES10005 is a heated oxygen sensor built for front-position applications that require a 3-wire, flat-connector design with an 18 x 1.5 mm thread. It draws on Delphi’s OE heritage and decades of supplier experience to deliver a direct-fit emission control replacement for select Chevrolet, GMC, Jeep, Buick, Oldsmobile, and Pontiac vehicles.

Compatible With front oxygen sensor applications on vehicles such as the Chevrolet Corvette, Chevrolet S10, GMC Sonoma, and Jeep Cherokee, this Delphi ES10005 oxygen sensor is specified for 325 mm overall length applications. It is a practical choice when replacing a worn sensor on older GM trucks, SUVs, and Jeep platforms.

• Heated oxygen sensor for faster operating temperature and stable signal output
• 3-wire design with flat connector shape
• 18 x 1.5 mm thread size for listed applications
• 325.0 mm overall length
• Front position application
• Package contents include the oxygen sensor and instruction sheet
• Delphi ES10005 part number for direct reference and ordering

Detailed Description

The Delphi ES10005 oxygen sensor is engineered for emission control service where accurate exhaust feedback is needed for fuel management and catalyst monitoring. Delphi builds aftermarket parts using OE knowledge developed through long-term work with major automakers, and that experience is reflected in the sensor’s fitment-specific design and connector configuration. This part cross-references Bosch (e.g., 12008, 13077) for the same application.

Use this sensor for listed front oxygen sensor locations on 1990-1995 Chevrolet Corvette, 1992-1995 Chevrolet S10, 1992-1995 GMC Sonoma, and 1986-1990 Jeep Cherokee applications, along with other covered Chevrolet, GMC, Buick, Oldsmobile, and Pontiac models. The Delphi ES10005 is also referenced by part number ES10005 for easy lookup across catalogs and service records.

What This Sensor Helps Address

• Check engine light concerns related to oxygen sensor performance
• Rough idle or inconsistent air-fuel feedback from a failing front sensor
• Reduced fuel control accuracy caused by slow sensor response
• Emission test failures tied to aging exhaust monitoring components
• Signal issues from cracked, contaminated, or worn original sensors

Installation Notes and Tips

Verify the vehicle’s original connector style, thread size, and overall length before installation. This sensor is specified for front-position applications with a flat connector and 325 mm overall length, so matching the existing harness and exhaust bung is important for proper fitment. Follow the included instruction sheet and confirm the sensor is installed in the correct front location for the listed application.

Quality Assurance
