dvups1 Posted August 7, 2008 Share Posted August 7, 2008 Hi all! I have a 1993 Accord with 141,000 miles on it. It is an auto transmission. Recently, the D4 light on the instrument panel has started blinking. I have been searching and searching but can't find the answer. I jumped the blue service connector and retrieved a code 13. Main shaft speed pulse generator open or shorted. The car runs fine. It shifts fine. There seems to be no other problem other than the flashing D4. I pulled the radio backup fuse for 20 seconds to try and reset the code but it came right back. Does anyone have a direction they can point me in? Thanks Link to comment Share on other sites More sharing options...

Tubbith Posted August 7, 2008 Share Posted August 7, 2008 Might be your first clue. Logic and reason, how often does it go over well online? Link to comment Share on other sites More sharing options...
