RodA2003 Posted April 14, 2005 Share Posted April 14, 2005 P1507 Idle Control System Malfunction (Fail Safe) I got the above code on a MT 2000 OB. Any pointers on how to fix the problem? Idle speed is a bit erratic. Rod Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted April 15, 2005 Share Posted April 15, 2005 Is the CEL on all the time, or did it go on once, and you get that code. If it's not on all the time, I'd suggest just driving it, and keeping an eye on things. The idle air control valve may have had a hiccup, or it may be sticking due to carbon build up.
