Delphi ES10143 Oxygen Sensor - Left or Right

Delphi ES10143 Heated Oxygen Sensor Overview

The Delphi ES10143 is a heated oxygen sensor designed for precise emission control in select Ford and Mazda vehicles. Engineered to provide accurate air-fuel mixture readings, this sensor supports optimal engine performance and reduced emissions.

• Heated oxygen sensor with 3-wire configuration
• Square connector shape for secure fitment
• Thread size: 18 x 1.5 mm for direct replacement
• Overall length of 350.0 mm for proper installation
• Compatible with left, right, and upstream positions depending on vehicle requirements
• Includes oxygen sensor and instruction sheet

Technical Details and Compatibility

The Delphi ES10143 oxygen sensor features a heated design that allows it to reach operating temperature quickly, improving sensor response time and emission control efficiency. The 3-wire setup supports both signal and heater circuits, ensuring reliable performance. Its square connector shape and 18 x 1.5 mm thread size make it a direct fit for specific Ford and Mazda models, including the Ford Probe and Mazda 626 and MX-6. The sensor’s 350 mm overall length accommodates proper placement in the exhaust system, whether installed on the left or right side or in the upstream position.

Applications and Common Issues Addressed

• Helps maintain proper air-fuel ratio for efficient combustion
• Reduces engine misfires and rough idling caused by faulty oxygen sensors
• Supports emission system compliance by monitoring exhaust gases
• Prevents increased fuel consumption due to inaccurate sensor readings
• Assists in avoiding check engine light triggers related to oxygen sensor faults

Installation Notes and Tips

When installing the Delphi ES10143 oxygen sensor, ensure the vehicle is compatible with the part number and thread size. Use anti-seize compound on the threads to facilitate future removal but avoid contaminating the sensor tip. Confirm the sensor’s position (left, right, upstream) matches the vehicle’s specifications. Proper torque should be applied to avoid damage to the sensor or exhaust components. Refer to the included instruction sheet for detailed installation guidance.
