Product Description
The genuine OEM Nissan 27731-37N0A fast idle actuator (also known as ACTUATOR-FICD - Fast Idle Control Device) is a premium-quality electromechanical component that plays a vital role in stabilizing engine idle speed under increased load conditions.
Operating Principle and Function
The role of the FICD valve is to admit auxiliary air into the intake manifold when additional load is placed on the engine—most commonly upon activating the air conditioning (A/C) compressor or operating the power steering. This extra air volume allows the engine control unit (ECU) to raise the idle speed, thereby preventing engine hesitation, rough running, or stalling.

Typical Symptoms of Failure
