Subthrottle Valve Actuator (Service Code 62)
FUEL SYSTEM (DFI) 3-67
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 surface.
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 that 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 Inspection).
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 reading 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). Not For Resale
