GPD 1814977 Ignition Knock Detonation Sensor Replacement

The GPD 1814977 is a direct-fit replacement ignition knock sensor, also known as a detonation sensor, engineered to OE specifications for a precise fit and reliable performance. GPD (Global Parts Distributors) has been a trusted supplier of quality automotive components since 1974, delivering parts built to meet or exceed original equipment standards.

What It Does:

The knock sensor monitors the engine block, cylinder head, or intake manifold for abnormal vibrations caused by engine knock, pre-ignition, or detonation. When irregular combustion is detected, it sends a signal to the engine control module (ECM), which adjusts ignition timing to prevent engine damage and restore optimal performance.

Key Features:

• Engineered to OE specifications for direct-fit replacement
• Detects engine knock and detonation to protect against internal engine damage
• Helps the ECM optimize ignition timing for improved efficiency and performance
• Constructed from durable materials for long service life
• Backed by GPD's 12-month warranty against defects in materials and workmanship

Replacing a failed knock sensor restores your engine's ability to self-correct ignition timing, preventing rough running, power loss, and potential long-term damage caused by undetected detonation.
