AA THROTTLE POSITION SENSOR INSTALLATION
1. Set the throttle position sensor on the throttle body as
shown in illustration (1).
2. Turn and set the throttle position sensor to the position
shown in illustration (2), connect a circuit tester across
terminal No. 2 (Throttle position sensor output) and
terminal No. 4 (earth), and measure the output voltage.
Tighten the throttle position sensor with a screw at the
position where the output voltage is at the standard value.
Standard value: 0.535 - 0.735 V

3. After installing the Throttle position sensor, check that
the output voltage is at the standard value. If deviated
from the standard value, loosen the screw, readjust to
the standard position, and then fix. Repeat this step until
the output voltage is at the standard value.
4. Connect a circuit tester across terminal No. 1 (Throttle
position sensor power) and terminal No. 2 (Throttle
position sensor output). Check that the resistance
changes smoothly when the throttle valve is slowly moved
to the fully opened position.
