Fast Idle Cam (FIC) Inspection and Adjustment

COMPONENT DESCRIPTION
The FIC is installed on the throttle body to maintain adequate engine speed while the engine is cold. It is operated by a volumetric change in wax located inside the thermo-element. The thermo-element is operated by engine coolant temperature.

COMPONENT INSPECTION AND ADJUSTMENT
Perform inspection and adjustment as follows:




1. Make sure the engine has cooled down and remove the throttle body.
2. Leave the throttle body for more than 3 hours so the temperature of the thermowax levels with the ambient air temperature.
Avoid direct sunlight or other heat source (heater, air conditioner, etc.).




3. Check dimension L1 without removing thermowax from throttle body. Measure ambient air temperature with a thermometer.







4. Check the clearance A between the stopper and the throttle adjusting screw (TAS). If not within specifications (the hatched area as shown in the figure below), adjust clearance using screw S.
Do not adjust the clearance using the throttle adjusting screw (TAS).
5. After adjusting clearance A, tighten the lock nut of screw S.
6. Install the throttle body.
7. Warm up engine to normal operating temperature. Confirm there is clearance between FIC and roller.
