Delphi AS10013 Ignition Knock (Detonation) Sensor

Delphi AS10013 Knock Sensor for GM Applications

The Delphi AS10013 ignition knock sensor is built for vehicles that need accurate detonation detection and stable engine control feedback. It draws on Delphi’s OE experience and is a direct-fit style replacement for a wide range of GM cars and vans, including Buick Century, Chevrolet Impala, and Pontiac Grand Prix applications.

Key Features

• Ignition knock (detonation) sensor for engine knock detection
• Threaded nut mounting type for secure installation
• Female round connector with 1 connector and 1 terminal
• Blade terminal design with male terminal gender
• Package includes the sensor and instruction sheet
• OE heritage and aftermarket engineering from Delphi

Product Details

Delphi AS10013 is an emission control sensor used to monitor engine knock and send signal input to the vehicle’s control system. That feedback helps the engine management system adjust timing when detonation is detected, which is important for smooth operation and consistent performance. This part cross-references Standard Ignition KS49 and Walker Products 242-1021 for the same application. Compatible with many GM platforms, it is a strong match for drivers searching for a knock sensor for 2000-2005 Chevrolet Impala, a replacement knock sensor for 1996-2005 Pontiac Grand Am, or a Delphi AS10013 sensor for 1996-2003 Pontiac Grand Prix.

What It Helps Address

• Check engine light related to knock sensor circuit faults
• Engine pinging or spark knock under load
• Unstable ignition timing caused by poor knock feedback
• Reduced drivability from inaccurate detonation sensing
• Failed emissions-related sensor performance

Installation Notes and Tips

Verify connector shape, terminal style, and threaded mounting before installation. Inspect the sensor mounting surface and wiring connector for corrosion, damage, or contamination before connecting the new unit. Use the vehicle’s service information for torque and location details, and confirm the application against the exact year, make, and model listed for Delphi AS10013.

Quality Assurance

Delphi builds this sensor using OE experience developed through long-term supply relationships with major automakers. The design reflects original-equipment knowledge applied to aftermarket replacement parts for GM fitments such as Buick Century, Chevrolet Monte Carlo, and Pontiac Aztek.
