General Description
VIS (Variable intake system) is a device which varies the length of intake manifold to genetate maximum power at certain RPM. VIS lengthens intake manifold to improve the torque at low RPM when vehicle speed is low while it shortens intake manifold to raise torque at high RPM when vehicle speed is high. PCU controls VIS using RPM signal.
DTC Description
Checking the output voltage from VIV (Variable Intake Manifold Valve) every 10 sec. under detecting condition, if the value within detecting condition lasts for more than 5 sec., ECM sets P0660. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
