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
Earth
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.
