Detailed Product Description

The Delphi ES10333 oxygen sensor is a critical component in the emission control system of Volkswagen vehicles such as the Cabrio, Corrado, Golf, Jetta, and Passat. Its heated sensor type allows the unit to reach operating temperature quickly, ensuring accurate oxygen level readings even during cold starts. The 4-wire configuration supports both the sensor signal and the heating element, enhancing responsiveness and durability. The flat connector shape simplifies the electrical connection process, reducing installation time and potential errors. With a thread size of 18 x 1.5 mm and an overall length of 625.0 mm, this sensor is engineered to fit precisely in the upstream position, where it measures exhaust gases before they reach the catalytic converter.

Common Applications and Issues Addressed

• Helps maintain proper air-fuel ratio for efficient combustion
