What is idle air control circuit?
Commonly called an idle air control (IAC) valve or idle speed control (ISC) valve, this device is used on many cable-operated throttle bodies to regulate the engine idle speed. This process is completed by regulating airflow through a bypass circuit around the throttle plate to increase or decrease idle speed.
What does idle air control system RPM higher than expected?
A P0507 code is a generic powertrain code that stands for “’Idle Control System RPM Higher than Expected.” This OBD-II code belongs to a series of fault codes (P0505 to P0509) that pertain to a fault in the idle control system, and it means that the engine computer has detected that the engine idle speed has exceeded
What is the idle control system?
The idle speed control mode is used to prevent engine stall during idle. The goal is to allow the engine to idle at as low an RPM as possible yet keep the engine from running rough and stalling when power-consuming accessories, such as air-conditioning compressors and alternators, turn on.
