P2071 CADILLAC Description
An Intake Manifold Tuning (IMT) Valve is used to change the intake manifold plenum configuration. When the IMT valve is open, the intake manifold is configured to one large plenum. When the IMT valve is closed, the intake manifold is configured to 2 smaller plenums. The IMT valve improves engine performance at low and high engine speeds depending on the engine load. The Diagnostic Trouble Code (DTC) will set when the control module detects that the IMT valve is stuck closed. This diagnostic runs continuously when the above conditions are met.
