THROlTLE POSITION SENSOR INSPECTION
(I) Disconnect the throttle position sensor connector.
(2) Measure resistance between terminal 1 (sensor earth) and
terminal 4 (sensor power).
Standard value : 3.5-5.5 M
(3) Correct a pointer type ohmmeter between terminal 1
(sensor earth) and terminal 3 (sensor output).
(4) Operate the throttle valve slowly from the idle position to
the full open position and check that the resistance
changes smoothly from in proportion with the throttle
valve opening angle.
(5) If the resistance is out of specification, or fails to change
smoothly, replace the throttle position sensor.
Throttle position sensor installation torque :
1.5-2.5 Nm (1.1-1.8 ft.lbs.)
For the Idle position switch and throttle position sensor
adjusting procedure, refer to P.14-65.

INSPECTION
(1) With the accelerator pedal released, check to be sure that
the throttle valve lever or the fixed SAS is pushed.
NOTE
If it is not pushed, adjust the fixed SAS (Refer to P.14-66.)
(2) Disconnect the throttle position sensor connector.
(3) Check the continuity across the throttle position sensor
connector terminal 1 (Sensor earth) and 2 (Idle position
switch).

NOTE
If there is no continuity when the accelerator pedal is
returned, loosen the throttle-position sensor installation
screw; then, after turning all the way in the clockwise
direction, check again.
(4) Replace the throttle-position sensor (idling-position switch
incorporated) if there is a malfunction.
NOTE
For replacement procedure, refer to the idle position
switch and throttle position sensor adjustment section
(P.1465).
