Thanks for visiting
Check the resistance of the IAC valve windings, the specification is approximately 22 ohms for all windings. If any of the circuits test open or show very low resistance, replace the IAC. Inspect the ECM for being burned internally, in most cases the IAC damages the ECM and both components have to be replaced. After repairs are made, perform the Idle Air Volume Learning Procedure. In some cases the ECM may be covered by the 8 year 80,000 mile emissions warranty.
