Intake Manifold Tuning Valve System

Intake Manifold Tuning Valve System

When the entry conditions have been met, the control module checks the commanded versus actual position of the Intake Manifold Tuning (IMT) valves. If they are not matched, a timer is started. If at the end of the set time the commanded and actual positions of the IMT valves do not match then the relevant DTC is flagged and the IMT valve affected is disabled.
