The Idle Speed Controller (ISC) is an electrically controlled device, which gets its input from the vehicle's ECU. The actuator consists of a linear servo actuator servomotor that controls a plunger which varies air flow through the throttle body.

Although the ISC is supposed to last the vehicle's lifetime, various reasons may cause it to fail/malfunction prematurely. The most common failure mode is partial/complete jamming of the actuator/motor (due to dirt/dust or even oil) where it cannot be smoothly controlled
