The Delphi ES10318 oxygen sensor is designed for precise emission control in select Geo and Toyota vehicles. This non-heated sensor features a 2-wire design and a square connector shape, ensuring reliable performance in upstream and downstream positions.

• Non-heated oxygen sensor type for accurate air-fuel mixture readings
• 2-wire configuration compatible with specific vehicle wiring harnesses
• Square connector shape for secure and proper fitment
• Thread size of 18 x 1.5 mm for direct replacement installation
• Overall length of 450 mm to accommodate various mounting locations
• Includes oxygen sensor and instruction sheet for installation guidance
• Compatible with front, rear, and upstream positions depending on vehicle requirements

Technical Details and Compatibility

The Delphi ES10318 oxygen sensor is engineered to meet the emission control needs of Geo and Toyota models such as the Celica, Corolla, Paseo, Previa, Prizm, and Tercel. Its non-heated sensor type relies on exhaust heat to reach operating temperature, making it suitable for vehicles designed for this sensor style. The 2-wire design simplifies installation and integration with the vehicle’s existing wiring. The square connector shape ensures a secure connection, reducing the risk of electrical issues. With a thread size of 18 x 1.5 mm and an overall length of 450 mm, this sensor fits precisely in designated upstream or downstream locations, depending on the vehicle’s emission system configuration.

Common Applications and Problem Resolution

• Helps maintain optimal air-fuel ratio for efficient engine performance
• Reduces harmful emissions by providing accurate oxygen level data to the engine control unit
• Addresses issues such as rough idling caused by faulty oxygen sensors
• Prevents check engine light triggers related to oxygen sensor faults
• Improves fuel economy by ensuring proper combustion monitoring

Installation Notes and Tips

When installing the Delphi ES10318 oxygen sensor, verify the correct sensor position (front, rear, or upstream) based on your vehicle’s specifications. Use the included instruction sheet for guidance on torque specifications and connector engagement. It is recommended to inspect the wiring harness and connector for damage before installation. Applying anti-seize compound to the sensor threads can facilitate future removal but avoid contaminating the sensor tip. Proper installation ensures accurate sensor readings and long-term reliability.

Quality Assurance and Warranty

Delphi oxygen sensors are manufactured to meet OEM standards for fit, form, and function. The ES10318 part number undergoes rigorous quality control to ensure durability and consistent performance in emission control systems. While specific warranty details may vary, Delphi typically offers coverage against defects in materials and workmanship, providing confidence in the sensor’s reliability for Geo and Toyota applications.
