Idle Air Control Valve: Testing and Inspection
Cleaning and Inspection
-
Clean the IAC valve O-ring sealing surface, pintle valve seat and air passage.
-
Use carburetor cleaner and a parts cleaning brush to remove carbon deposit. Do not use a cleaner that contain methyl ethyl ketone. This is an
extremely strong solvent and not necessary for this type of deposit.
-
Shiny spots on the pintle are normal and do not indicate misalignment or a bent pintle shaft.
-
Inspect the IAC valve O-ring for cuts, cracks or distortion. Replace the O-ring if damaged.
