Delphi AS10260 Ignition Knock (Detonation) Sensor

Delphi AS10260 Ignition Knock Sensor

Delphi AS10260 is an ignition knock (detonation) sensor built for OE-style replacement on a range of GM and related vehicles. It uses a bolt-on mounting design with a female oval connector and 2 male terminals for a direct-fit service replacement.

Compatible with 2003-2006 Buick, Cadillac, Chevrolet, GMC, Hummer, Oldsmobile, Pontiac, and Saab applications, this Delphi knock sensor supports accurate engine knock detection for vehicles such as the Buick Lucerne, Cadillac DTS, and Chevrolet Colorado. The AS10260 part number is also a useful reference when matching the correct sensor for service work.

Key Features

• Ignition knock (detonation) sensor for engine knock detection
• Bolt-on mounting type for secure installation

Detailed Description

Delphi AS10260 is engineered as an OE-style ignition knock sensor for vehicles that rely on precise detonation monitoring to help the engine control system adjust timing. Delphi draws on long-term OE experience and supplier knowledge, and that background is reflected in the design and construction of this aftermarket replacement. If you are servicing a Buick Lucerne, Cadillac DTS, or Chevrolet Colorado, AS10260 provides a direct replacement path for the original knock sensor application.

This part cross-references Standard Ignition KS197 for the same application.
