ISC(IDLE SPEED CONTROL)ACTUATOR. the isc actuator wich is under pcm(powertrain control module) control controls the amount of air entering the intake plenum at idle.
Actuator speed is determined by:
Stepper idle speed actuator in carbureted vehicles it is used to control the engine's idling RPM. It also regulates the position of the throttle valve plate.
To change the actuator speed in a hydraulic system, you can adjust the flow rate of the hydraulic fluid supplied to the actuator. This can be achieved by modifying the pump speed, using flow control valves, or adjusting the size of the orifices in the system. Additionally, incorporating variable displacement pumps allows for more precise control of flow rates and, consequently, actuator speed. Care should be taken to ensure that pressure and system limits are not exceeded during adjustments.
On idle speed control actuator is located on the front of the air intake plenum
Flow rate is directly proportional to actuator speed. Increasing the actuator speed will result in higher flow rates, while decreasing actuator speed will decrease flow rates. Actuator speed controls the flow of a fluid or material through a system by adjusting the rate at which the actuator allows the material to flow.
It is probably the cruise control actuator cable. The actuator is what, through the commands of the cruise control system and driver imputs, determin a speed setting
The idle speed for a 2002 Mazda Tribute typically ranges between 600 to 800 RPM when the engine is warm. It's important to check the owner's manual or a service manual for specific details, as variations can occur depending on the engine type and conditions. If the idle speed is consistently outside this range, it may indicate a need for maintenance or adjustments.
meter in: regulates the speed of the actuator by controling the amount of fluid entering in to the actuator. meter out: regulates the speed of the actuator by controling the amount of fluid leaving the actuator. bleed off: regulates the speed of the actuator by metering a part of the pump flow to the tank.

An idle speed control actuator is a device used in internal combustion engines to regulate the engine's idle speed. It adjusts the amount of air entering the engine when the throttle is closed, ensuring smooth operation at idle and preventing stalling. Typically, it is controlled electronically, responding to signals from the engine control unit (ECU) based on factors like engine temperature and load conditions. This actuator helps maintain optimal engine performance and fuel efficiency during idle conditions.
Actuator speed is determined by:
A meter-out flow control circuit is a hydraulic system designed to regulate the flow of fluid exiting a hydraulic actuator, such as a cylinder. In this configuration, a flow control valve is placed on the outlet side of the actuator, allowing precise control over the speed of the actuator's extension or retraction. This setup helps maintain a consistent speed and prevents cavitation or sudden movements, ensuring smoother operation in applications where precise motion is critical. Additionally, it can help improve energy efficiency by minimizing pressure drops.
