Detailed Description

The Delphi AS10262 knock sensor is designed to monitor engine vibration patterns and send the signal needed for proper ignition control. When the engine management system receives accurate knock feedback, it can adjust timing to help maintain smooth operation and protect the engine from detonation-related stress. Delphi draws on more than 100 years of OE experience, and that background is reflected in the fit, connector design, and service-focused construction of this replacement sensor.

Use AS10262 on a broad range of GM vehicles, including Buick Enclave, Chevrolet Malibu, Chevrolet Traverse, GMC Acadia, Cadillac CTS, and Chevrolet Colorado applications listed in the fitment data. The part number AS10262 is also a useful reference when matching the correct sensor for service work on 2009-2023 model-year vehicles across multiple platforms.

What It Helps Fix

• Knock sensor fault codes
• Check engine light related to detonation sensor performance
• Erratic ignition timing caused by inaccurate knock feedback
• Engine pinging or spark knock concerns tied to sensor failure
• Driveability issues from a failed or contaminated knock sensor

Installation Notes and Tips

Confirm connector shape, terminal count, and mounting style before installation. AS10262 uses a bolt-on design with one oval female connector and pin terminals, so matching the original sensor configuration is important for proper fitment. Review the included instruction sheet before service, and inspect the mounting surface and wiring connector for corrosion or damage during replacement.
