    DTC P1077: IMT System Malfunction (Low rpm) Stuck Short


    Intake Manifold Tuning System.


    Intake Manifold Tuning (IMT) System
    Engine power is optimized by closing and opening the intake manifold tuning (IMT) valve. When the valve is closed, there is high torque at low engine speed. When the valve is open, there is high torque at high engine speed.

    Could be bad valve, defective intake manifold, or just bad electrical connection to the solenoid valve.
