ON-VEHICLE SERVICE
GENERAL
When the hoses have been disconnected and system’s component
removed for service, be sure to reinstall component properly, and
route and connect hoses correctly after service. Refer to Emission
Control Information Label for proper connection of hoses (if
equipped).
ACCELERATOR CABLE ADJUSTMENT
1) Confirm that ambient temperature is higher than 0_C, 32_F.
2) Warm up engine to normal operating temperature with all elec-
tric loads OFF and stop engine.
3) Confirm that clearance “c” between throttle lever (1) and stop
screw (2) is less than about 1 mm (0.04 in.).
4) Check accelerator cable for play.
Accelerator cable play “a”: 10 – 15 mm (0.4 – 0.6 in.)
Cable play should be within specification. If out of specification,
loosen accelerator cable lock nut and adjust by turning adjusting
nut (3). Be sure to tighten lock nut (4) securely after adjustment.
5) With accelerator pedal depressed fully, check clearance be-
tween throttle lever and lever stopper (5) (throttle body) which
should be within following specification.
Clearance “b”: 0.5 – 2.0 mm (0.02 – 0.07 in.)
(With pedal depressed fully)
If measured value is out of specification, adjust it to specification
by changing height of pedal stopper bolt (6).
