Fast Idle Cam: Testing and Inspection

COMPONENT INSPECTION AND ADJUSTMENT
1. If engine is not completely cold, remove throttle body from engine. Then, wait for at least 3 hours.
(This step is necessary to bring the temperature of the thermo-element to the room temperature.
2. Measure thermo-element stroke (L) and room temperature.




3. Check thermo-element stroke (L) as shown in the figure. If the stroke is not within the range 0 replace thermo-element with new one. Then return to step 1 again.




4. Adjust clearance (A) between throttle stopper and throttle adjusting screw to specification by turning adjusting screw (S).

5. Rotate adjusting screw (S) clockwise or counterclockwise by Z turns according to the following equation, then tighten the adjusting screw lock nut.

Z = L- Ls / Y

*: Value of the specified line (Ls) at the temperature of thermoelement actually measured.

Y = 0.8 mm (0.031 in)

Direction of adjusting screw (S) rotation
(1) Positive (+) Z: Counterclockwise
(2) Negative (-) Z: Clockwise
