Please someone help us? My car has been down since July 13th and my hubby worked on it yesterday again and was hopin it was fixed. Drove it 35 miles one way and back no issues and let it sit for about 3 hrs and then drove it 2 miles to town and check engine light comes on. Go to advance and they hook it up to computer and said Idle air control vavle. Does anyone have a pic of exactly where it is on 2003 Hyundai Sonata

 

What engine? 2.4L 4-cyl or 2.7L V6? What was the exact code?


2.4L:

DESCRIPTION
The idle speed control actuator (ISCA) is installed on the throttle body and controls the intake airflow that is bypassed around the throttle plate. The function of ISCA is to maintain idle speed according to various engine loads and conditions, and also to provide additional air during starting. Moreover, it performs electronic dashpot during deceleration. The ISCA consists of opening coil, closing coil, and permanent magnet. Based on information from various sensors, the ECM controls both coils by grounding their control circuit. According to the control signals from the ECM, the valve rotor rotates to control the bypass airflow into engine.

Should be in a similar location near the throttle body on the 2.7L V6.
