Delphi AS10009 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor for GM V6 and V8 Applications

The Delphi AS10009 ignition knock sensor is built for vehicles that rely on accurate detonation detection to help the engine control system manage spark timing. It is a direct-fit emission control sensor for a wide range of Buick, Chevrolet, Pontiac, and Oldsmobile applications, including the Buick LeSabre, Chevrolet Impala, and Pontiac Grand Prix.

• Ignition knock (detonation) sensor for engine knock detection
• Pin terminal design with 1 female connector and 1 male terminal
• Round connector shape for OE-style electrical connection
• Threaded nut mounting type for secure installation
• Package includes the sensor and instruction sheet
• Delphi AS10009 replacement for select GM vehicles

OE-Style Design and Fitment

Delphi brings more than a century of OE experience to the AS10009, with engineering knowledge drawn from supplying major automakers. That OE heritage is reflected in the sensor’s construction and connector layout, helping maintain the original electrical interface on applications such as the 2000-2005 Chevrolet Impala, 1997-2008 Pontiac Grand Prix, and 1996-2005 Buick LeSabre. This part cross-references Standard Ignition KS45 and KS277 for the same application.

What This Sensor Helps Address

• Knock sensor fault codes related to detonation detection
• Engine pinging or spark knock under load
• Rough timing control caused by a failing sensor signal
• Check engine light concerns tied to knock sensor performance
• Driveability issues on GM Buick, Chevrolet, Pontiac, and Oldsmobile platforms

Installation Notes

Verify connector style, mounting type, and engine application before installation. The AS10009 uses a threaded nut mount, a round female connector, and a single pin terminal layout. Mounting hardware is not included. Follow the instruction sheet in the package and inspect the harness connector and mounting surface for corrosion or damage before fitting the new sensor.

Quality Assurance

Delphi designs aftermarket parts using OE heritage and supplier experience built over 100 years. The AS10009 is engineered to meet the electrical and fitment expectations of select GM applications, including Buick Park Avenue, Chevrolet Monte Carlo, and Pontiac Bonneville models.
