• Overall length of 1130 mm to fit front position mounting
• Includes oxygen sensor and instruction sheet for installation guidance

Technical Details and Compatibility

The Delphi ES10399 oxygen sensor features a heated sensor type that allows for faster warm-up times and improved emission control. Its 4-wire design supports both sensor heating and signal transmission, enhancing durability and responsiveness. The flat connector shape simplifies connection to the vehicle’s wiring harness, reducing installation errors. With a thread size of 18 x 1.5 mm and an overall length of 1130 mm, this sensor is specifically designed for front position installation in Porsche 911 and Saab 9-3, 900, and 9000 models. The package includes the oxygen sensor itself along with an instruction sheet to assist with proper installation.

Applications and Problem Resolution

This oxygen sensor is used to monitor the oxygen levels in the exhaust gases, providing critical data to the engine control unit (ECU) for efficient fuel management and emission reduction. It is compatible with the following vehicles:

• Porsche 911 front oxygen sensor replacement
• Saab 9-3 front oxygen sensor upgrade
• Saab 900 and 9000 front sensor applications

Common issues addressed by the Delphi ES10399 include:

• Erratic engine performance due to faulty oxygen sensor readings
• Increased emissions and failed emission tests
• Poor fuel economy caused by incorrect air-fuel mixture data
• Check engine light triggered by sensor malfunction
• Delayed sensor warm-up affecting engine efficiency

Installation Notes and Tips

When installing the Delphi ES10399 oxygen sensor, ensure the vehicle is cooled down to avoid burns. Use the included instruction sheet for proper wiring and torque specifications. The flat connector shape requires alignment with the vehicle harness connector to prevent damage. Applying anti-seize compound on the threads can facilitate future removal. Verify sensor placement in the front position as specified for Porsche 911 and Saab 9-3, 900, and 9000 models.
