Cadillac Fleetwood Idle Control Valve
Idle Control Valve is used in Cadillac Fleetwood models where the ability of the engine to maintain a specific idle speed is determined by the amount of air that passes around the throttle plate. Called the idle air control (IAC) actuator, it is an electrically operated component that has an interface with the engine control unit (ECU) to allow the vehicle to idle smoothly irrespective of the loads imposed. The models of Cadillac Fleetwood are equipped with a linear servo motor mounted in the IAC actuator that controls the flow of air through the throttle body in order to maintain an appropriate idle speed. These valves are made for the longevity however; problems like jamming from dust or dirt can occur such as erratic idle. It is crucial to perform frequent general upkeep, such as cleaning, so that Idle Control Valves remain in good form and, in regards to existing issues for example air leaks, raised idle RPM.
Each OEM Cadillac Fleetwood Idle Control Valve we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part.

Cadillac Fleetwood Idle Control Valve Parts Questions & Experts Answers
- Q: What is the purpose of the Idle Control Valve and how can it be tested for problems?A: The Idle Control (IAC) system is responsible for controlling engine idle speeds and preventing stalls caused by changes in engine load. The system works by allowing a controlled amount of air to bypass the throttle blade via the IAC valve. The valve consists of a rotating shutter that is held in a neutral position by opposing springs. The PCM controls the valve using two control circuits, one to open the valve and one to close it. By modulating the frequency of the control signals, the PCM can adjust the idle speed. To test for IAC-related problems, preliminary checks should be done to ensure proper connections, inspect the wire harness for damage, check for a restricted air intake system, and look for vacuum leaks. If a scan tool is available, the RPM can be commanded while monitoring the engine speed. If the IAC valve responds correctly, it is functioning properly. If a scan tool is not available, resistance tests can be performed on the IAC terminals. If the resistances are within specifications, the IAC circuits should be checked for continuity back to the PCM. If everything is functional, the PCM may be faulty. To remove and install the IAC motor, the necessary steps should be followed for the specific engine type. After installation, minimum air, Throttle Position Sensor (TPS), and idle learn adjustments should be performed.
