chilkoot Posted April 4, 2010 Share Posted April 4, 2010 '93 LS400, ~140k miles. Yesterday on my way home from work my TRACoff and CE lights turned on. When I drove to work last night, they were still on. The car does not sound any different, nor have I had any issues with it in quite some time. My only suspicion is the alternator, it has been on the way out for quite a while now, and I suspect it has finally kicked it. However, I used to own a '90 and when the alternator failed it lit up every dash light, not just the CEL and TRACoff. Did they change the dash indications from '90 to '93? Only other thing I can think of that would logically trip those two lights would be the TPS. Any suggestions? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
OLD SkOOL VIP Posted April 26, 2010 Share Posted April 26, 2010 I had the same problem on my 1993. Check all the connections. Mines happens to be the AFM plug was lose. Quote Link to comment Share on other sites More sharing options...
RDM Posted April 26, 2010 Share Posted April 26, 2010 Instead of stabbing at guesses, why not pull the codes and see what comes up? It could be a faulty ignition coil, injector, coolant temperature sensor, anything ECU related. Pull the codes and you'll have your answer.
