Subthrottle Valve Actuator Input Voltage Connections to Adapter:
(I) Digital Meter (+) → R (actuator BK/O) lead Digital Meter (–) → Battery (–) terminal (II) Digital Meter (+) → BK (actuator G) lead Digital Meter (–) → Battery (–) terminal (III) Digital Meter (+) → W (actuator P/BL) lead Digital Meter (–) → Battery (–) terminal (IV) Digital Meter (+) → Y (actuator Y/BK) lead Digital Meter (–) → Battery (–) terminal
Input Voltage
Standard: About DC 8.5 10.5 V and
then 0 V or
About DC 8.5 10.5 V
If the reading is in specification, but the actuator does not operate, replace the throttle body assy.
If the reading is out of the specification, remove the ECU and check the wiring for continuity between main harness connector.
Special Tool - Hand Tester: 57001-1394
Disconnect the ECU and actuator connectors.
