GPD 1811958 Knock Sensor Engine Detonation Sensor

The GPD 1811958 is a replacement knock sensor designed to detect engine detonation and pre-ignition events, allowing the engine control module (ECM) to make real-time ignition timing adjustments to protect the engine and maintain optimal performance. GPD (Global Parts Distributors) manufactures this sensor to meet or exceed OEM specifications for a direct-fit, plug-and-play installation.

Key Features:

• Detects harmful engine knock and detonation before damage occurs
• Sends signal to ECM to retard ignition timing as needed
• Built to OEM specifications for reliable, accurate performance
• Direct-fit replacement for easy, no-modification installation
• Durable construction for long service life under demanding under-hood conditions

A faulty knock sensor can trigger a check engine light, reduce fuel economy, and leave the engine vulnerable to serious damage from detonation. Replacing it with the GPD 1811958 restores proper engine management function and helps protect your investment.
