Delphi AS10002 Ignition Knock (Detonation) Sensor - Right

Ignition Knock Sensor for GM Applications

Delphi AS10002 is an ignition knock (detonation) sensor built for direct-fit service on select Chevrolet, GMC, and Oldsmobile vehicles. It uses a single-pin, round-connector design with a threaded nut mount for a secure OE-style installation.

Backed by Delphi’s OE heritage and decades of supplier experience, this sensor is built with the application details that matter for accurate engine knock detection on vehicles such as the Chevrolet S10, GMC Sonoma, and Chevrolet C1500.

Detailed Description

Delphi AS10002 is an OE-style knock sensor engineered for vehicles that rely on precise detonation feedback to help the engine control system manage spark timing. This part cross-references Standard Ignition KS29 and KS40 for the same application. It also matches a range of GM fitments, including Chevrolet S10, Chevrolet S10 Blazer, GMC Jimmy, GMC Sonoma, Chevrolet C1500, and GMC C1500 applications, depending on year and engine layout.

Use AS10002 when replacing a failed knock sensor on 1992-1996 Chevrolet, GMC, and Oldsmobile models listed in the fitment data. The part number AS10002 appears in service searches for front right and rear-mounted GM knock sensor locations, including engine-block and rear-of-head placements.

What This Sensor Helps Address

• Check engine light related to knock sensor circuit faults
• Audible spark knock or detonation under load
• Incorrect ignition timing caused by faulty knock feedback
• Rough engine performance tied to sensor signal loss
• Diagnostic trouble codes associated with detonation sensing
