1. Measure:
• Throttle position sensor output
voltage
Out of specification → Adjust.
NOTE:
• Be sure to adjust the throttle valve’s open-
ing before measuring the throttle position
sensor output voltage.
• When measuring the throttle position sen-
sor output voltage, set the digital tester to
the manual range.
Measuring steps
(1) Remove the intake silencer. Refer to
“INTAKE ASSEMBLY” on page 4-3.
(2) Disconnect the throttle joint link rod 1
at the throttle body.
(3) Check the throttle valve.
(4) Connect the test harness (3-pin) as
shown.
(5) Connect the digital tester probes to the
test harness (3-pin) as shown.
(6) Turn the engine start switch on.
(7) Measure the output voltage.
(8) Install the intake silencer.
(9) Start the engine and measure the out-
put voltage again.
