Delphi AS10216 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor for OE-Style Engine Control

Delphi AS10216 is an ignition knock (detonation) sensor built for precise engine feedback in emission control systems. It uses a bolt-on mounting design with a rectangular female connector and male blade terminals for a direct-fit style replacement on supported vehicles.

Backed by Delphi’s OE heritage and decades of supplier experience, this sensor is made for drivers and technicians who need accurate knock detection on applications such as the Buick Regal, Chevrolet Malibu, and GMC Terrain.

Key Features

• Ignition knock (detonation) sensor for engine timing feedback
• Bolt-on mounting type for secure installation
• Rectangular 1-connector design with female connector gender
• 2-terminal blade connection layout
• Includes sensor and instruction sheet
• Delphi AS10216 OE-style replacement part

Detailed Description

The Delphi AS10216 knock sensor monitors engine vibration patterns and sends signal data to the vehicle’s control system so ignition timing can be adjusted when detonation is detected. That function is important for maintaining smooth operation, protecting the engine from abnormal combustion, and supporting emissions-related performance. This part cross-references Standard Ignition KS393 for the same application.

Compatible With 2013-2016 Buick Verano, 2011-2013 Buick Regal, 2011 Saab 9-5, 2010 Buick LaCrosse, 2009-2010 Chevrolet Malibu, and 2010 GMC Terrain. It also serves additional listed applications including Chevrolet Cobalt, Chevrolet Equinox, Chevrolet HHR, Pontiac G6, Saturn Sky, Saturn Vue, Pontiac G5, Pontiac Solstice, and Saturn Aura. Delphi AS10216 is a practical choice when replacing a failed knock sensor on supported GM and Saab platforms.

What It Helps Address

• Check engine light related to knock sensor circuit faults
• Audible spark knock or pinging under load
• Reduced engine performance from incorrect timing control
• Rough operation caused by inaccurate detonation feedback
• Emission control faults tied to sensor signal issues

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. The sensor uses a bolt-on design and a single rectangular connector, so matching the original configuration is important for proper fitment. Follow the included instruction sheet and inspect the mounting surface and wiring connector for corrosion or damage before installing the new part.

Quality Assurance

Delphi builds aftermarket parts using OE experience and knowledge developed through long-term supplier relationships with major automakers. That background supports consistent fit, signal accuracy, and application-specific design for the Delphi AS10216.
