This code can be misleading when it states on your OBDII code reader " Idle control valve stuck open". I replaced this valve as per the reader, but fault remained. It was the MAF sensor at fault. Now don't do what I initially did and buy a "Cheap Chinese unit for $30" It lasted 3 kms then went dead. Buy the genuine item or aftermarket of good reputation. Good luck. Hourie
