Delphi AS10007 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor for OE-Style Engine Control

Delphi AS10007 is an ignition knock (detonation) sensor built for vehicles that rely on accurate knock detection to manage spark timing and engine performance. With OE heritage behind the design, this sensor supports precise signal delivery for a range of Buick, Chevrolet, Cadillac, Oldsmobile, and Pontiac applications.

Compatible With 1987-1996 Buick Century, Regal, and Skylark; Chevrolet Cavalier, Corsica, Lumina, Monte Carlo, and Celebrity; Cadillac DeVille, Eldorado, Seville, Allante, and Cimarron; Oldsmobile Cutlass Ciera, Cutlass Cruiser, Cutlass Supreme, Achieva, Aurora, and Firenza; and Pontiac Grand Am, Grand Prix, Sunbird, and 6000. Delphi AS10007 is a direct-fit ignition knock sensor for many GM vehicles from the late 1980s through the mid-1990s.

• Ignition knock (detonation) sensor for engine knock detection
• Threaded nut mounting type for secure installation
• 1 round male connector with 1 female terminal
• Pin terminal design for OE-style electrical connection
• Package includes the sensor and instruction sheet
• Delphi OE heritage and aftermarket engineering

Detailed Product Overview

Delphi AS10007 is engineered for applications where the engine control system depends on a stable knock sensor signal to adjust ignition timing. The sensor uses a round, single-connector design with pin terminals and threaded nut mounting, matching the style used across many GM platforms. This makes it a practical replacement for drivers servicing older Buick, Chevrolet, Cadillac, Oldsmobile, and Pontiac models, including the Buick Century, Chevrolet Lumina, and Pontiac Grand Prix.

This part cross-references Standard Ignition KS8 and Walker Products 242-1017 for the same application.

What It Helps Address

• Knock sensor fault codes related to detonation detection
• Erratic ignition timing caused by a weak or inconsistent sensor signal
• Engine pinging or spark knock under load
• Reduced drivability from inaccurate knock feedback to the ECU
• Check engine light concerns tied to knock sensor circuit issues

Installation Notes and Tips

Verify connector shape, terminal style, and mounting type before installation. Delphi AS10007 uses a threaded nut mount, a round connector, and a single male connector interface, so matching the original sensor configuration is important for proper fitment. Follow the included instruction sheet and inspect the harness connector and mounting surface for corrosion or damage before installing the new sensor.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers. That OE background is reflected in the design and engineering of AS10007, helping support consistent fit and signal performance across the listed GM applications.
