DTC P2070: Intake Manifold Tuning (IMT) Valve Stuck Open. 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 IMT valve assembly consists of the following:

" A tuning valve

" A microprocessor

" An electric motor

" A hall-effect sensor

" An ignition voltage circuit

" A ground circuit

" An IMT valve control circuit

" An IMT valve signal circuit

this is the descripition, it should be ok to drive, but I would get it fixed ASAP.
