H
(1) Install throttle position sensor on throttle body and
temporarily tighten screw.
Caution
Adjust the throttle position sensor and idling speed
control according to the engine load condition.
(2) Check correct installation of the throttle position sen-
sor. While moving the throttle lever in both open and
close directions, that resistance between terminals
@and
@ or @ and @ changes. If resistance changes
smoothly, the throttle position sensor has been instal-
led correctly.
AFTER REASSEMBLY INSPECTION
IDLE POSITION SWITCH CONTINUITY CHECK
(1) Using a circuit tester, check continuity between the body
and terminal
@I when the throttle valve is fully closed and,riwhen fully opened.

slowly operate the throttle valve until it is at its maximum
open position and check that the resistance changes
smoothly.

H;OSECaution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressure
in the fuel pipe line.
INSPECTIONN14GCAll Check the hoses and the pipes for crack or damage.
l Check the fuel tank cap for malfunction.
l Check the fuel tank for deformation, corrosion or crack.
0,. Check the fuel tank for dust or foreign material.
NOTE
If the inside of the fuel tank is to be cleaned, use any one ofthe following:
(1) Kerosene
(2)
Trichloroethylene-(3) A neutral emulsion type detergent
OVERFILL LIMITER (TWO-WAY VALVE)
Set a hand vacuum pump at inlet side or outlet side; the valve
is good if, when a negative pressure (vacuum) is applied, air
flows after a slight negative pressure is initially maintained.
SERVICE POINTS OF INSTALLATION.
Nl4DDAL15. INSTALLATION OF ELECTRICAL FUEL PUMP
(1) Align the three positioning projections of the packing
with the holes in the fuel pump.
(2) When the fuel pump is installed, the holding bolt at the
lower side of the fuel tank should be installed first.
Care should be taken at this time that the O-ring is not
pinched.14. INSTALLATION OF FUEL GAUGE UNIT
Align the two positioning projections of the packing with
the holes in the fuel gauge unit.
Caution
When mounting the fuel gauge unit, incline the float at
the end leftward, and insert it into the fuel tank. Since
the reserver cap is provided in the fuel tank, the fuel
gauge unit will contact the reserver cap if the fuel
gauge unit is inclined rightward during insertion.
