    DTC 33 Intake Shutter Control Circuit Malfunction

    CIRCUIT DESCRIPTION
    When the ignition switch turned OFF, the intake shutter control system shuts off the air intake by closing the
    intake shutter for the engine stopping smoothly. The actuator shuts the intake shutter by the engine ECU
    controlling the VSV.
    DTC No. DTC Detecting Condition Trouble Area
    S Open or short in VSV for intake shutter circuit
    S VSV for intake shutter
    Open or short in VSV for intake shutter circuit for 0.5 sec. or
    33 S Intake shutter
