Detailed Description

This knock sensor monitors engine vibration patterns and sends data to the engine control system so timing adjustments can be made when detonation is detected. Delphi’s OE-focused development and calibration process helps ensure the sensor delivers the correct signal for the application. This makes AS10296 a practical replacement for vehicles such as the 2001-2004 Chevrolet Silverado 1500, 2001-2004 GMC Sierra 1500, and 2000-2002 Cadillac DeVille.

Compatible With 2001-2005 Chevrolet Astro, 2002-2005 Chevrolet Blazer, 2001-2005 Chevrolet Express 1500, 2001-2005 Chevrolet Express 2500, 2001-2005 GMC Safari, 2001-2005 GMC Savana 1500, 2001-2005 GMC Savana 2500, 2002-2004 Chevrolet S10, 2001-2004 Chevrolet Silverado 1500, 2001-2004 GMC Sierra 1500, 2002-2004 GMC Sonoma, 2000-2002 Cadillac DeVille, 2000-2002 Cadillac Eldorado, 2000-2002 Cadillac Seville, 2001-2002 GMC Savana 3500, and 2001-2002 Oldsmobile Aurora.

What It Helps Address

• Knock sensor fault codes
• Erratic ignition timing caused by incorrect detonation feedback
• Engine pinging or spark knock concerns
• Check engine light conditions related to knock sensor performance
• Driveability issues tied to inaccurate engine vibration sensing

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. This sensor uses a single male rectangular connector with 2 terminals and does not include mounting hardware. Confirm the vehicle application against the fitment list for the exact year and model before ordering Delphi AS10296.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards to support accurate readings and consistent performance. That validation process is intended to help reduce comebacks and maintain proper engine management signal quality across the listed Chevrolet, GMC, Cadillac, and Oldsmobile applications.
