    After the workshop clean driver cabin for my 7500 DT570 truck i found that:

    1- When starting truck the RPM increase to 1700 RPM without depressing accelerator pedal.
    2- When I disconnected the APS/IVS connector the rpm go down to normal range
    3- No Engine codes appeared

    Is this the APS/IVS problem and how to fix it?

    Make sure they didn't get something stuck under the pedal and it is partially held down.
