Actuator Cable Adjustment

1. Check that the actuator cable moves smoothly with

no binding or sticking.

2. Measure the amount of movement of the output

linkage until the engine speed starts to increase. At

first, the output linkage should be located at the

fully closed position. Free play should be 5 ± 0.5 mm

(0.20
±
0.02 in).
