Subthrottle Valve Actuator (Service Code 62)
Subthrottle Valve Actuator Removal
CAUTION
Do not remove the subthrottle valve actuator [A]
since it has been adjusted and set with precision
at the factory.
Never drop the actuator , especially on a hard sur-
face. Such a shock to the actuator can damage it.
Audible Inspection
NOTE
○
Be sure the battery is fully charged.
•
Turn the ignition switch ON and ensure t hat the actuator
valves open and close ( make light sounds) several times
within seconds, and then close at the idle throttle opening
position.
•
Turn the ignition switch OFF.
If the actuator does not work as described above, do the
visual inspection.
Visual Inspection
•
Remove the throttle body assy (see Throttle Body Assy
Removal).
•
Turn the ignition switch ON.
•
Check to see that all the subthrottle valves [A] open and
close smoothly.
If the subthrottle valves do not operate, check the actuator
internal resistance (see Resistance I nspection).
Resistance Inspection
•
Turn the ignition switch OFF.
•
Remove the throttle body assy (see Throttle Body Assy
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: BK/BL lead [1] ←→ P/BL lead [2]
G lead [3] ←→ W/BL lead [4]
Standard: About 5 ∼ 7kΩ
Special Tool - Hand Tester : 57001–1394
If the r eading is out of the range, replace the actuator
along with the throttle body assy.
If the reading is within the range, check the input voltage
(see Input Voltage Inspection).
