GPD 1811779 Ignition Knock Detonation Sensor

The GPD 1811779 is a direct-fit replacement ignition knock sensor (also known as a detonation sensor) engineered to restore proper engine management function. GPD (Global Parts Distributors) has been a trusted supplier of quality automotive components since 1974, manufacturing parts designed to meet or exceed original equipment fit, form, and function.

What Does a Knock Sensor Do?

The knock sensor is mounted on the engine block, cylinder head, or intake manifold. It detects abnormal engine vibrations caused by pre-ignition or detonation — commonly known as engine knock or ping. When the sensor detects these vibrations, it signals the engine control module (ECM) to adjust ignition timing, protecting the engine from damage and optimizing performance.

• 100% tested for durability and performance prior to packaging
• Direct-fit replacement — no modification required
• Manufactured to professional quality standards
• Restores proper ECM ignition timing control
