Delphi AS10376 Ignition Knock (Detonation) Sensor - Left

Ignition Knock Sensor Overview

Delphi AS10376 is an ignition knock sensor built for Mercedes-Benz applications that require accurate detonation detection and OE-style signal consistency. It uses a screw mount, a single oval connector, and a supplied wiring harness to support clean sensor replacement on covered vehicles.

Key Features

• OE-calibrated sensor output for accurate knock detection
• Wiring harness included for a cleaner service replacement
• Oval 1-connector design with 2-pin male terminals
• Screw-mounted construction for secure installation
• Delphi AS10376 fitment spans multiple Mercedes-Benz models and model years

Detailed Description

Delphi AS10376 is part of a sensor portfolio developed and validated to OE standards. For Mercedes-Benz vehicles such as the G550, AMG GT, and C63 AMG, this knock sensor helps the engine control system monitor detonation events with the signal accuracy needed for proper timing control. The left-side fitment listed for select applications should be matched carefully to the vehicle configuration before ordering. This part cross-references Standard Ignition KS470 for the same application.

Common Issues It May Solve

• Knock sensor fault codes related to detonation monitoring
• Erratic ignition timing caused by inaccurate sensor input
• Reduced engine performance from a failed knock sensor signal
• Check engine light concerns tied to sensor circuit faults
• Service issues on Mercedes-Benz engines requiring OE-style sensor calibration

Installation Notes and Tips

Confirm the vehicle year, model, and listed position before installation. Match the connector shape, terminal count, and harness length to the original part, and inspect the mounting point for damage or contamination before securing the sensor. Delphi AS10376 uses a screw mount and includes a wiring harness, but mounting hardware is not listed as included.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards and uses product validation methods to support accurate readings and reduce comebacks. Part number AS10376 is backed by that OE-focused development process.
