Delphi ES11078 Oxygen Sensor - Front

Delphi ES11078 Oxygen Sensor Overview

The Delphi ES11078 is a non-heated oxygen sensor designed for precise emission control in select Saturn vehicles. Engineered to meet OEM specifications, this sensor ensures accurate air-fuel mixture readings for optimal engine performance and reduced emissions.

• Non-heated oxygen sensor type for reliable operation
• Single wire design simplifies installation
• Round connector shape for secure fitment
• Thread size of 18 x 1.5 mm compatible with front position mounting
• Includes oxygen sensor and instruction sheet for proper installation

Detailed Product Description

The Delphi ES11078 oxygen sensor is specifically designed for front position installation on Saturn SC1, SC2, SL, SL1, SL2, SW1, and SW2 models. Its non-heated sensor type uses a single wire to transmit accurate oxygen level data to the vehicle’s engine control unit (ECU). The round connector shape and 18 x 1.5 mm thread size ensure a secure and precise fit, maintaining the integrity of the emission control system. This sensor helps maintain proper combustion efficiency by monitoring exhaust gases and enabling the ECU to adjust fuel delivery accordingly.

Common Applications and Issues Addressed

• Helps resolve rough idling caused by incorrect air-fuel mixture
• Reduces engine hesitation and stalling related to faulty oxygen sensor readings
• Assists in lowering harmful emissions to meet environmental standards
• Prevents check engine light triggers related to oxygen sensor faults
• Improves fuel economy by ensuring accurate sensor feedback

Installation Notes and Tips

When installing the Delphi ES11078 oxygen sensor, ensure the vehicle is cool to avoid burns. Use the included instruction sheet for guidance on proper torque specifications and connector engagement. The single wire design simplifies wiring connections, but verify the round connector is fully seated to prevent signal loss. It is recommended to inspect the sensor’s thread size (18 x 1.5 mm) compatibility with your Saturn model before installation.
