IACV
INSPECTION
The IACV is installed on the throttle body and is
operated by the step motor. When the ignition
switch is turned ON, the IACV operates for a few
seconds.
Check the step motor operating (beep) sound with
the ignition switch turned ON.
The IACV operation can be checked visually as fol-
lows:
1. Remove the IACV (page 5-79).
2. Connect the IACV 4P (Black) connector.
3. Turn the ignition switch ON.
REMOVAL
• Always clean the throttle body before the IACV
removal to prevent dirt and debris from entering
the IACV passage.
Remove the air cleaner housing (page 5-62).
Disconnect the IACV 4P (Black) connector.
Remove the screws, IACV cover and O-ring.
