IDLE POSITION SWITCH ADJUSTMENT
Caution
N14UDAThe idle position switch has been adjusted by the manu-
facturer.Do not, therefore, disturb the setting of the idle-position
switch.
If the setting is disturbed as a result of carelessness, or if
the idle-position switch is replaced, make the necessary
setting as described below.
(1) Sufficiently loosen the tension of the accelerator cable.
(2) Disconnect the connector of the idle position switch (fixed
speed adjusting screw).
(3) Loosen the lock nut of the idle position switch (fixed speed
adjusting screw).
(4) Sufficiently loosen the idle position switch by turning it in
the counterclockwise direction and fully close the throttle
valve.Caution
Be sure to completely close the throttle valve.
(5) Connect a tester (ohm range) between the switch’s
terminal and the body.
(6) Turn down the idle position switch until it enter the “ON”
state where the switch establishes a continuity to body
(this point is called “touch point”). Turn the switch down
15/16 of a turn more from that point.
NOTEThe “touch point” refers to the point where the throttle
valve begins opening.
(7) While holding the idle position switch to make sure that it
does not turn, tighten the lock nut.
(8) Adjust the accelerator cable.
(9) Adjust the basic idle speed. (Refer to P.14-48.)
(lO)Setting the throttle position sensor.
FUEL PRESSURE TESTN14FNAO(1) Reduce the fuel pressure in the fuel line.
(Refer to
P.14-44.)(2) Disconnect the high pressure fuel hose from the delivery
pipe.Caution
Cover the hose connection with shop towel to prevent
splash of fuel that could be caused by residual pressurein the fuel pipe line.
(3) Remove the throttle body stay.
