Detailed Product Description

The Delphi ES10955 oxygen sensor is engineered to monitor exhaust gases and provide critical data to the engine control unit (ECU) for optimal combustion and emission control. Its non-heated sensor type relies on exhaust heat to reach operating temperature, making it suitable for front or rear positions depending on the vehicle's specific requirements. The 2-wire configuration simplifies installation and wiring compatibility with Toyota Camry, Celica, and MR2 models. The sensor's square connector shape ensures a secure and stable connection, while the 18 x 1.5 mm thread size matches OEM specifications for proper mounting. With an overall length of 450 mm, this sensor fits well within the exhaust system layout of the compatible vehicles.

Common Applications and Issues Addressed

• Helps maintain proper air-fuel ratio for efficient engine performance
• Reduces harmful emissions by providing accurate oxygen level data
• Resolves check engine light triggers related to oxygen sensor faults
• Improves fuel economy by enabling precise fuel mixture adjustments
• Prevents engine misfires caused by incorrect oxygen sensor readings

Installation Notes and Tips

Before installation, verify the sensor position (front or rear) specific to your Toyota Camry, Celica, or MR2 model. Use the included instruction sheet for detailed guidance. Ensure the thread size of 18 x 1.5 mm matches the mounting port. Avoid over-tightening to prevent damage to the sensor or exhaust components. Disconnect the battery before installation to prevent electrical shorts. After installation, clear any diagnostic trouble codes to reset the ECU.
