Common symptoms of a bad Idle Air Control Valve (IAC) and how to fix it. Read here for more information: https://www.backyardmechanic.org/symp... • An Idle Air Control (IAC) valve is controlled by the computer and allows air to bypass the throttle body butterfly plate. • Some Newer vehicles don't use an IAC but have an Electronic Throttle Body (ETB) System, which controls the throttle butterfly plate. • A bad Idle Air Control will only affect the idle of the engine, but engine will run well when the gas pedal is pressed. • Symptoms of a Bad Idle Air Control Valve • Idle Speed Erratic • Idle Speed Too High • Idle Speed Too Low (Stalling) • DTC Error Codes (P0505 to P0509) • How To Fix a Bad Idle Air Control Valve • An intake air leak can cause the same symptoms as a bad IAC since it is letting air in around the throttle body. • The most common fix is to clean the IAC of carbon build-up, but it may also have failed or have a wiring issue. • If the IAC is cleaned, the engine may run badly for 2-3 minutes until the cleaner is burnt away. • By using this information user assumes all risk of use.
