billydpowell Posted April 26, 2010 Share Posted April 26, 2010 this has turned out to be a real challenge, this is my 1999 LS400. I turn the light off, and within 20 miles, it is back on. I had Auto zone check it and they reported codes, 1345 & 1354 which are: 1345 CS position sensor malfunction,... open, short, or failed AND 1354 VVT system malfunction... valve timing off, blocked oil passage, failed oil control valve or electrical circuit fault the car starts,runs and handles perfect, without any noise. ANY IDEAS?? any simular situations?? I have checked gas cap, swapped batterys with my 97 LS, cleaned battery cable ends, plus the double cables on the positive connector.

1990LS400 Posted April 27, 2010 Share Posted April 27, 2010 How "easy" do you want? The procedure in your owners manual takes about 30 seconds. Or just disregard the VSC warning and it may go off on its own after a few hours of driving. The VSC warning has usually gone off before I had time to follow the owners manual procedure. But if this is from "running off a curb", there is a possibility damage has occured that should be investigated. Quote Link to comment Share on other sites More sharing options...

dcfish Posted April 27, 2010 Share Posted April 27, 2010 Sounds like the wheel speed sensor took a hit. Quote Link to comment Share on other sites More sharing options...

billydpowell Posted May 7, 2010 Author Share Posted May 7, 2010 Well I found out the oil control valve was not working, I pulled it out, it was dirty, so I cleaned it out, put it back in and it seems to be working SO FAR.... sure beats the $365 quote.... 160 parts, 200 labor .... it took me 45 minutes to remove, clean and replace.. $200??????? __________________ Quote Link to comment Share on other sites More sharing options...
