Delphi AS10315 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor Overview

Delphi AS10315 is an ignition knock sensor built for direct-fit service on select Subaru applications. It uses OE-calibrated sensing and a compact electrical design to deliver accurate signal feedback for engine management systems.

• OE-developed and product-validated sensor construction
• Calibrated to OE standards for accurate readings
• Rectangle connector with 2 terminals and male connector gender
• Blade terminal type with a screw-style mounting design
• Wiring harness included for a complete sensor assembly

Fitment Details

Fits 2010-2012 Subaru Legacy, N/A. Fits 2010-2012 Subaru Outback, N/A. This part cross-references Standard Ignition KS381 for the same application.

How This Sensor Is Used

• Addresses knock sensor fault codes related to abnormal combustion detection
• Helps restore accurate engine timing feedback after sensor wear or failure
• Supports smoother engine control when the original sensor signal becomes inconsistent
• Replaces a damaged connector or harness-integrated sensor assembly

Installation Notes

Confirm connector shape, terminal count, and mounting style before installation. Match the harness length and sensor layout to the original part, and verify the vehicle’s service procedure for torque and connector routing. AS10315 should be installed as a direct replacement on the listed Subaru Legacy and Subaru Outback applications.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and tested to OE standards for signal accuracy. AS10315 is part of Delphi’s sensor lineup for emission and engine management applications.
