GPD 1815026 Ignition Knock Detonation Sensor

The GPD 1815026 is a direct-fit replacement ignition knock (detonation) sensor engineered to meet or exceed original equipment fit, form, and function. The knock sensor is located on the engine block, cylinder head, or intake manifold, where its function is to sense unusual vibrations caused by engine pre-ignition or detonation.

When the engine control module (ECM) detects knocking or pinging via this sensor, it adjusts ignition timing to protect the engine from damage. A failed knock sensor can trigger a check engine light, cause poor fuel economy, and lead to long-term engine wear — making prompt replacement critical.

Key Features:

• Designed to meet or exceed OE fit, form, and function
• 100% tested for durability and performance
• Direct-fit replacement — no modification required
• Engineered to stringent OE specifications to fit and function the same or better than the original part
• Backed by GPD's one-year warranty against defects in material and workmanship

The GPD 1815026 knock sensor is a reliable, professional-grade replacement for drivers and technicians seeking a cost-effective OE-quality solution.
