When trouble code P2070 sets on a Chevy Uplander, the engine control unit (ECU) has determined that the intake manifold tuning (IMT) valve is stuck open. The ECU gets this information from a position sensor that is built into the tuning valve actuator.Having a P2070 IMTV stuck open can be a valve of the intake stuck open or binding. This can result in the IMTV to fail also. When You do not repair this, You will not have the full benefit of performance that the engine can produce in horsepower. It does not exhibit any drivability problem and You would not know it was not functional unless an ECM reported it.

A stored code p2070 means an intake manifold tuning (imt) valve has been detected by the powertrain control module (pcm) which is stuck open for engine bank two.
