Delphi ES10320 Oxygen Sensor

Delphi ES10320 Oxygen Sensor Overview

The Delphi ES10320 oxygen sensor is designed for upstream emission control applications in Geo and Toyota vehicles, including the Corolla and Prizm models. This non-heated sensor features a 2-wire configuration and a square connector shape, ensuring reliable performance and compatibility with specific engine management systems.

• Non-heated oxygen sensor type for upstream position
• 2-wire design with square connector shape
• Thread size of 18 x 1.5 mm for secure installation
• Overall length of 450.0 mm for proper fitment
• Includes oxygen sensor and instruction sheet

Technical Details and Specifications

The Delphi ES10320 oxygen sensor is engineered to meet the emission control requirements of Geo and Toyota vehicles, specifically the Corolla and Prizm models. Its non-heated sensor type operates without an internal heating element, relying on exhaust heat to reach operating temperature. The 2-wire configuration simplifies wiring and installation, while the square connector shape ensures a precise fit with the vehicle’s harness. The sensor’s thread size of 18 x 1.5 mm matches OEM specifications, and the overall length of 450.0 mm allows for proper positioning in the upstream location of the exhaust system.

Compatible Vehicles and Applications

This oxygen sensor is compatible with the following makes and models:

• Geo Prizm
• Toyota Corolla

It is designed for upstream installation, where it monitors oxygen levels in the exhaust gases before they reach the catalytic converter. This data is critical for the engine control unit to optimize fuel mixture and reduce emissions.

Common Issues Addressed by the Delphi ES10320 Oxygen Sensor

• Improves fuel efficiency by providing accurate oxygen level readings
• Helps reduce harmful emissions by enabling proper air-fuel mixture adjustments
• Prevents engine performance problems related to faulty oxygen sensors
• Resolves check engine light triggers caused by sensor malfunctions
• Supports smooth engine idling and acceleration

Installation Notes and Tips

When installing the Delphi ES10320 oxygen sensor, ensure the vehicle is cooled down to avoid burns. Use the correct 18 x 1.5 mm thread size to avoid cross-threading. Verify the square connector shape matches the vehicle’s wiring harness for a secure connection. Follow the included instruction sheet for torque specifications and wiring guidance. Proper installation in the upstream position is essential for accurate sensor readings and optimal engine performance.
