Return Spring Removal
                            NOTICE
    Do not remove return spring in the gear case [A]
    since it has been set with precision at the factory.

Return Spring Inspection
• Turn the ignition switch off.
• Remove
   Air Cleaner Housing (see Air Cleaner Housing Re-
      moval(3-54))
•   Check that the throttle valves [A] move lightly by pushing
    finger without the spring force.
    If the throttle valves move lightly, the return spring is bro-
    ken, replace the throttle body assy.
    If the throttle valves move hardly and return them by the
    return spring, check the output voltage of the throttle posi-
    tion sensor (see Throttle Position Sensor Output Voltage
    Inspection(17-20)).
    If the output voltage is good, replace the ECU.
