Throttle Body: Service and Repair

DISASSEMBLY STEPS
1. IAC (AIS) motor assembly
2. Throttle body

CAUTIONS:

1. When loosening a Phillips screw which has been firmly tightened, use a Phillips screwdriver that is an exact fit for the screw.
2. Do not remove the throttle valve.
3. Be careful when removing the IAC (AIS) motor mounting screws, as adhesive has been applied to these screws.

CLEANING THROTTLE BODY PARTS
1. Clean all throttle body parts. Do not use solvent to clean the following parts:

^ Throttle position sensor
^ AC (AIS) motor

If these parts are immersed in solvent, their insulation will deteriorate. Wipe them with shop towel only.
2. Check if the vacuum port or passage is clogged. Use compressed air to clean the vacuum passage.
