Delphi AS10373 Ignition Knock (Detonation) Sensor

Delphi AS10373 Ignition Knock Sensor

The Delphi AS10373 ignition knock sensor is built for accurate detonation detection and OE-style signal consistency. It supports proper engine timing control for select Lexus and Toyota applications, including Lexus GS300, Toyota Corolla, and Toyota Supra.

Key Features

• Ignition knock (detonation) sensor for engine knock detection
• OE-calibrated and tested to support accurate readings
• Round connector with 1 male terminal and 1 male connector
• Screw-mount design for direct replacement service
• No wiring harness included
• No mounting hardware included

Detailed Description

Delphi AS10373 is an emission control sensor engineered to monitor engine knock and send precise feedback to the engine management system. Delphi validates its sensors to OE standards, helping maintain consistent signal output and reduce repeat repairs. This makes it a practical replacement for vehicles that rely on accurate detonation sensing to manage ignition timing and engine performance. This part cross-references Standard Ignition KS110 for the same application.

Compatible With select 1995-2000 Lexus and Toyota applications, including Fits 1995-1997 Lexus GS300, N/A; Fits 1995-1997 Toyota Celica, N/A; Fits 1995-1997 Toyota Corolla, N/A; Fits 1995-1998 Toyota Supra, N/A; Fits 1995-1999 Toyota Paseo, N/A; Fits 1995-1999 Toyota Tercel, N/A; Fits 1998-2000 Lexus LX470, N/A; Fits 1998-2000 Toyota Land Cruiser, N/A; and Fits 2000 Toyota Tundra, N/A.

What It Helps Address

• Knock sensor fault codes
• Erratic ignition timing caused by inaccurate detonation feedback
• Engine pinging or spark knock under load
• Check engine light concerns related to knock sensor performance
• Driveability issues tied to poor engine control input

Installation Notes and Tips

Install the sensor using the screw-mount location specified for the vehicle application. Verify connector shape, terminal count, and harness condition before installation. Because no mounting hardware or wiring harness is included, reuse or source the required vehicle-specific components as needed. Confirm the replacement against the original sensor and vehicle service information before final assembly.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods. Each sensor is tested and calibrated to OE standards to support accurate readings and consistent operation in service.
