ENGINE CONTROL SYSTEM 17100010102
GENERAL INFORMATION
A cable-type accelerator mechanism and a
suspended-type pedal have been adopted.
Accelerator pedal position sensor is used for
vehicles with 4G6 engine which is equipped with
the electronically-controlled fuel injection system.

Accelerator cable play mm 1-2
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. (Refer to
GROUP 11 - On-vehicle Service.)
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.
<4G6>
(1) Loosen the adjusting nut, and then move the lever
to throttle fully-closed position.
(2) Tighten the adjusting nut until the lever start to move,
turn back one turn, and then tighten the lock nut
to the specified torque.
<4G9>
(1) Loosen the adjusting bolt or adjusting nut to release
the cable.
(2) Move the plate until the inner cable play is at the
standard value, and then tighten the adjusting bolt
or adjusting nut.
(3) After adjusting, check that the throttle lever is touching
the stopper.
