Global Parts 1815037 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor for OE-Style Engine Monitoring

Global Parts 1815037 is an ignition knock sensor for vehicles that rely on accurate detonation detection to manage engine timing. It monitors unusual vibration at the engine block, cylinder head, or intake manifold so the engine control system can respond to pre-ignition or knock conditions.

Key Features

• Blade terminal design with a rectangular female connector
• 2-terminal electrical connection for direct sensor signal routing
• Engine knock sensor for emission control and ignition management systems
• OE-style replacement for select Mercedes-Benz, Saturn, and Toyota applications
• Part number 1815037 for easy catalog matching

Detailed Description

This Global Parts knock sensor is built for vehicles that use a dedicated detonation sensor to help the engine control module detect abnormal combustion events. By sensing vibration changes at the engine block, cylinder head, or intake manifold, it supports timing correction and engine protection. It is a direct-fit service part for applications including Mercedes-Benz C230, S320, C280, C36 AMG, E320, SL320, C220, Saturn Astra, and Toyota Matrix. This part number 1815037 also cross-references Standard Ignition KS255 for the same application.
