id0113b1804700
With Variable Intake Air Shutter Valve Actuator Only
Operation inspection
1. Disconnect the negative battery cable.
2. Remove the variable intake air shutter valve actuator.
3. Connect the battery positive voltage to terminal A or B, and verify that the gear moves.
-
• If there is no malfunction, carry out the “Circuit Open/Short Inspection”.
• If there is any malfunction, replace the variable intake air shutter valve actuator.

Circuit open/short inspection (without throttle valve actuator)
1. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)
-
Open circuit
-
• If there is no continuity, the circuit is open. Repair or replace the wiring harness.
-
― Variable intake air shutter valve actuator terminal A and PCM terminal 2AO
― Variable intake air shutter valve actuator terminal B and PCM terminal 2AS
-
Short circuit
-
• If there is continuity, the circuit is shorted. Repair or replace the wiring harness.
-
― Variable intake air shutter valve actuator terminal A and power supply
― Variable intake air shutter valve actuator terminal A and body ground
― Variable intake air shutter valve actuator terminal B and power supply
― Variable intake air shutter valve actuator terminal B and body ground
