    Possible causes

    – The EVAP control system pressure sensor circuit is open or shorted
    – EVAP control system pressure sensor may be faulty

    Possible solution

    – Retight gas cap – Replaced EVAP Control System Pressure Sensor

    Yes, I have heard of and used a smoke machine to find leaks in the evap system. In fact if you have a leak in the evap system, this is the best way to find a leak.
