It has one oval-shaped female connector with two male terminals, designed to interface seamlessly with the vehicle’s wiring harness. The sensor mounts securely using a bolt-on method, providing a firm fit without the need for additional mounting hardware. This sensor is engineered specifically for emission control systems in Chevrolet and GMC vehicles, including the Express 1500, Savana 1500, Sierra 1500, and Silverado 1500 models.

Function and Common Applications

This ignition knock sensor plays a critical role in detecting engine detonation or knocking, allowing the engine control unit (ECU) to adjust ignition timing accordingly. Proper function of this sensor helps maintain engine performance and fuel efficiency.

• Detects engine knocking to prevent damage
• Helps optimize ignition timing for better performance
• Reduces harmful emissions by supporting emission control systems
• Prevents engine misfires related to detonation
• Supports smooth engine operation under varying load conditions

Installation Notes and Tips

Installation of the Delphi AS10272 sensor requires removal of the old knock sensor and mounting the new sensor using the bolt-on method. Ensure the sensor is securely fastened to the engine block to maintain accurate knock detection. The sensor’s blade terminals and oval female connector should be connected carefully to avoid damage. Since mounting hardware is not included, use the existing bolts or appropriate replacements. Follow the included instruction sheet for detailed installation guidance.
