Delphi ES10926 Oxygen Sensor - Front

Delphi ES10926 Oxygen Sensor Overview

The Delphi ES10926 oxygen sensor is a front-position emission control sensor built for precise air-fuel monitoring. It uses a 5-wire design with a flat connector and 18 x 1.5 mm thread size, making it a direct-fit option for select Cadillac Catera and Saturn L300, LS2, and LW2 applications.

Delphi draws on OE experience from supplying top automakers, and that heritage is reflected in the sensor design and fitment details. If you are replacing a front oxygen sensor on a 1999-2001 Cadillac Catera or a 2000-2005 Saturn L300, this Delphi ES10926 part number is built around the original application requirements.

Key Features

• Front oxygen sensor for emission control systems
• 5-wire configuration for the specified application
• Flat connector shape for OE-style electrical connection
• 18 x 1.5 mm thread size for proper mounting
• Overall length: 565.0
• Includes oxygen sensor and instruction sheet
• Cross-reference example: Bosch 16065, 16066

Detailed Fitment and Function

Compatible With 1999-2001 Cadillac Catera, front; 2000 Saturn LS2, front; 2000 Saturn LW2, front; and 2002-2005 Saturn L300, front. The Delphi ES10926 oxygen sensor helps the engine control module monitor exhaust oxygen content so fuel delivery can be adjusted accurately. That makes it an important replacement when the original front sensor is slow, contaminated, or no longer reporting correctly.

This part cross-references DENSO Auto Parts 234-5006 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect fuel trim readings from a worn front sensor
• Reduced fuel control accuracy during closed-loop operation
• Emissions test failures tied to sensor response issues
• Rough idle or drivability concerns caused by faulty exhaust feedback

Installation Notes and Tips

Verify the connector shape, wire count, thread size, and front position before installation. Compare the old sensor length and routing to the Delphi ES10926 to confirm proper fit on your Cadillac Catera or Saturn L300, LS2, or LW2. Follow the included instruction sheet and inspect the harness path for heat damage, corrosion, or exhaust leaks that could affect sensor performance.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and knowledge developed through long-term supplier experience with major automakers. That background supports consistent fit and function for emission control service on the listed vehicles.
