ON-VEHICLE SERVICE
ACCELERATOR CABLE CHECK AND
ADJUSTMENT
1. Turn A/C and lamps OFF.
Inspect and adjust at no load.
2. Warm engine until stabilized at idle.
3. Confirm idle speed is at prescribed value.
Standard value: 850±50 r/min
4. Stop engine (ignition switch OFF).
5. Confirm there are no sharp bends in accelerator cable.
6. Check inner cable for correct slack.
Standard value: 1 - 2 mm
7. If there is too much slack or no slack, adjust play by
the following procedures.
(1) Loosen the adjusting bolt to release the cable.
(2) Move the plate until the inner cable play is at the
standard value, and then tighten the adjusting bolt
to the specified torque.
Tightening torque: 5.0±1.0 N·m
