What determines an engines idle speed?
Idle speed, sometimes simply called “idle”, is the rotational speed an engine runs at when the engine is idling, that is when the engine is uncoupled from the drivetrain and the throttle pedal is not depressed. In combustion engines, idle speed is generally measured in revolutions per minute (rpm) of the crankshaft.
How does the idle speed control system work?
Idle speed control system. In addition, the digital engine control system receives digital on/off status inputs from several power-consuming devices attached to the engine, such as the air-conditioner clutch switch, park-neutral switch, and the battery charge indicator. These inputs indicate the load that is applied to the engine during idle.
What does the idle air control valve do?
The idle air control valve controls the air needed to maintain a steady idle speed. It essentially acts as a bypass of the throttle body plate.
What should I do if my idle control motor is disconnected?
The engine should still start and run without any issue despite the idle control motor being disconnected. Be sure to tuck the wiring you disconnected up in the engine bay so it doesn’t get caught in any moving parts. Look for a difference in idle speed.
What should resistance be for idle control motor?
Connect an Ohm meter to the two and measure the resistance between them. Fords are designed to operate with the resistance in the solenoid in a range between 7.0 to 13.0 ohms. If the resistance is outside that range, the idle control motor needs to be replaced.

What are the symptoms of bad idle speed control valve?
Below are the top 5 symptoms of a bad idle speed control valve. 1) Stalled Engine – A bad idle speed control valve will cause your engine to stall. Depending on the extent of the wear or damage to the valve, the engine will stall immediately after you start the car. Either that or it will stall after a couple of minutes.
What is an idle speed, no wake zone?
“Idle Speed, No Wake” Zone: A designated area where vessels must be operated at a speed no greater than that which is necessary to maintain steerage and headway. The vessel should not produce a wake at this speed. “Slow Speed, Minimum Wake” Zone: Areas where vessels must be fully off plane and completely settled in the water.
