Coming back from NY city there was CEL with TRAC OFF lights popped up, after checked by a Auto Zone they gave me the P0015 reading, After 60+ mile drive stopped to refuel, then this lights disappeared, could this be a faulty gas cap, There was no change or abnormal behavior shown from the vehicle with the CEL and TRAC OFF lights on.
