GPD 1812961 Knock Sensor OEM Replacement

The GPD 1812961 Knock Sensor is a direct OEM-replacement knock sensor engineered to restore proper engine detonation monitoring and protect your engine from damaging pre-ignition events. GPD (Global Parts Distributors) manufactures this sensor to meet or exceed original equipment specifications, ensuring a reliable, drop-in fit without modification.

The knock sensor continuously monitors engine vibration frequencies associated with detonation (engine knock or pinging). When knock is detected, the signal is relayed to the engine control module (ECM), which adjusts ignition timing to eliminate knock and safeguard internal engine components. A faulty knock sensor can result in retarded ignition timing, reduced fuel economy, loss of power, and an illuminated Check Engine light.

Key Features:

• Direct OEM replacement — engineered to match original fit, form, and function
• Accurately detects engine knock and detonation for precise ECM timing correction
• Manufactured by GPD to meet or exceed original equipment specifications
• Helps prevent engine damage caused by uncontrolled pre-ignition
• Resolves common DTCs related to knock sensor circuit faults
• Plug-and-play installation with OEM-style connector

GPD 1812961 is the manufacturer part number for this knock sensor. Always verify fitment for your specific application before installation.
