Delphi AS10233 Ignition Knock (Detonation) Sensor

OE-Style Knock Sensor for Audi and Volkswagen

Delphi AS10233 is an ignition knock sensor built for accurate detonation detection across a wide range of Audi and Volkswagen applications. It uses OE development and validation methods to deliver consistent signal output for engine management systems that rely on precise knock feedback.

Compatible With Audi Q5, Audi S4, Audi S5, Audi A6 Quattro, Audi A7 Quattro, Audi Q7, Audi R8, Audi A8 Quattro, Audi A6, Audi A5 Quattro, Audi A4 Quattro, Audi A4, and Volkswagen Touareg applications listed below.

• Delphi AS10233 ignition knock (detonation) sensor
• 3-terminal, male-pin design with a single oval connector
• Screw-mount configuration for direct sensor installation
• OE-calibrated and tested for accurate knock signal readings
• Built for engine control systems that monitor spark knock and detonation

Detailed Product Overview

This Delphi knock sensor is designed to detect engine vibration patterns associated with detonation so the ECU can adjust timing and protect the engine. The sensor measures 490 mm in length and uses a 1-connector, 3-terminal layout with a male connector and male terminals. Delphi validates and calibrates its sensors to OE standards, helping maintain accurate readings and reducing repeat repairs caused by incorrect signal output. This part cross-references Standard Ignition KS356 for the same application.

What It Helps Address

• Check engine lights related to knock sensor signal faults
• Audible spark knock or pinging under load
• Incorrect ignition timing caused by poor detonation feedback
• Engine performance issues tied to inaccurate sensor readings
• Diagnostic trouble codes associated with knock sensor circuits
