Subthrottle Valve Actuator Removal
NOTICE
Do not remove the subthrottle valve actuator [A]
since it has been adjusted and set with precision
at the factory.
Never drop the throttle body assy especially on a
hard surface. Such a shock to the subthrottle valve
actuator can damage it.

NOTE
○
Be sure the battery is fully charged.
•
Remove the air cleaner housing (see Air Cleaner Housing
Removal).
•
Turn the ignition switch on.
•
Check to see that all the subthrottle valves [A] open and
close smoothly.
•

•
Turn the ignition switch off.
•
Remove the air cleaner housing (see Air Cleaner Housing
Removal).
•
Disconnect the subthrottle valve actuator connector [A].
•
Connect a digital meter to the subthrottle valve actuator
connector [A].
•
Measure the subthrottle valve actuator resistance.
Subthrottle Valve Actuator Resistance
Connections: Y/BK lead [1] ←→ P/BL lead [2]
G lead [3] ←→ BK/O lead [4]
Standard: About 5.2
∼ 7.8 Ω
If the reading is out of the standard, replace the throttle
body assy.
If the reading is within the standard, check the input volt-
age (see Subthrottle Valve Actuator Input Voltage Inspec-
tion).
