Delphi AS10092 Ignition Knock (Detonation) Sensor

Delphi AS10092 Knock Sensor for Subaru

The Delphi AS10092 ignition knock sensor is built for Subaru engines that need accurate detonation detection and stable ignition control. It is a bolt-on, oval-connector sensor with a female connector and blade terminals, made for direct replacement service on select Subaru Forester, Impreza, Legacy, and Outback applications.

Key Features

• Part number: AS10092
• Ignition knock (detonation) sensor for emission control and engine management systems
• Bolt-on mounting type for secure installation
• Oval connector shape with 1 female connector
• 2 terminal design with blade terminals
• Package contents: ignition knock sensor and instruction sheet
• OE-focused engineering backed by Delphi’s long history supplying original equipment to major automakers

Application Details

Compatible With 1999-2002 Subaru Forester, 1999-2002 Subaru Impreza, 1999-2001 Subaru Legacy, and 2000-2001 Subaru Outback. The Delphi AS10092 is a direct-fit knock sensor solution for Subaru models that rely on precise signal input to help the engine control system manage spark timing under detonation conditions. This part cross-references Standard Ignition KS98 for the same application.

What It Helps Address

• Knock sensor fault codes
• Engine pinging or detonation-related drivability concerns
• Reduced ignition timing control from a failing sensor signal
• Check engine light concerns tied to knock sensor performance
• Unstable engine operation caused by inaccurate detonation feedback

Installation Notes

Install the AS10092 using the bolt-on mounting point and verify the connector style matches the vehicle harness before installation. Follow the included instruction sheet and inspect the mounting surface for corrosion, debris, or damage that could affect sensor readings. For Subaru Forester, Impreza, Legacy, and Outback applications, confirm the engine code and connector configuration against the vehicle service information before final assembly.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and engineering knowledge developed through decades of original equipment supply. The AS10092 reflects that background with application-focused design for Subaru knock sensor replacement service.
