No, I erase them with an OBDII scanner I got at Autozone. I disconnected the PE Comp today and it still would throw up a 0216, so that rules the Comp out. Another factor is I realized now that I ended up with an 027 spec pump instead of the 028 that is for the HO engine. The Cummins service man thinks it must have the correct spec of pump to run right. I am wanting to believe that is the problem, in any case they are sending me the correct spec pump, so I'll see if I can get it under 2 hours out and in. Also I will be replacing the cam sensor this time, for $40 it is too easy to replace at the same time.
