Code P2070 1998 Ford F150 Description

The Intake Manifold Tuning Valve (IMTV) is a motorized actuated unit mounted directly to the intake manifold. The IMTV actuator controls a shutter device attached to the actuator shaft. There is no monitor input to the Powertrain Control Module (PCM) with this system to indicate shutter position.
The motorized IMTV unit will not be energized below approximately 2600 rpm or higher on some vehicles. The shutter will be in the closed position not allowing airflow blend to occur in the intake manifold. Above approximately 2600 rpm or higher, the motorized unit will be energized. The motorized unit will be commanded on by the PCM initially at a 100 percent duty cycle to move the shutter to the open position and then falling to approximately 50 percent to continue to hold the shutter open.
The Intake Manifold Tuning Valve (IMTV) system is monitored for failure during continuous, Key ON Engine OFF (KOEO), or Key ON Engine Running (KOER) self-tests. The test fails when the signal is more or less than an expected calibrated range.
