Cadillac Eldorado Idle Control Valve
Stepping further with the detailing of Cadillac Eldorado's, one has to specifically discuss the Idle Control Valve, which works to control the idling speed of the engine by monitoring the air passing through the plate of throttle. This electrically operated device is specifically referred to as the idle air control (IAC) actuator and in conjunction with the engine control unit (ECU) ensures that the engine idles freely and does not stall regardless of the loading status. Cadillac Eldorado models incorporate a linear servo motor in the IAC to move a plunger in order to regulate the amount of airflow into the throttle body. These are valves that are built to last but they can at time jam due to dirt or dust and this cause erratic idling. Cleaning is also one of the most important part of maintenance which must be done from time to time to ensure the proper function and performance of Idle Control Valve in Cadillac Eldorado.

Cadillac Eldorado 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.
