tco43 Posted January 31, 2004 Report Share Posted January 31, 2004 Our 2001 STS occaisionally stumbles or dies outright. It will restart almost immediately, but can be really troublesome in a traffic light situation. It shows a PCM P0335 that I believe to be CPS A circuit malfunction. The Cadillac garage says they can be had for $56 and $64. Are they difficult to replace? Must the front mount come out? Are there problems to watch out for? The wiring seems ok, unless I missed something. Is there a trouble point to recheck? Thanks for any help. Paul. Link to comment Share on other sites More sharing options...
