    That is an Engine Crankcase Breather Oil Separator Speed Too Low. Your crankcase breather is on thepassengerr side of the engine just in front of the starter, it's a black cylindrical piece with a speed sensor on the top. If there is any oil leaking from it, it needs replaced.

    It most likely needs either a speed sensor or a breather.

    Did they do a speed sensor or a breather? It could also be engine harness or MCM problems.
