rfender Posted July 11, 2008 Share Posted July 11, 2008 Just purchased a 1992 LS400 with 198,000 miles. The car runs good but after 100 miles I got a check engine light. It is DTC 17. CMP No. 1 Could someone tell me what this means? Thanks! Quote Link to comment Share on other sites More sharing options...
gordonw Posted July 11, 2008 Share Posted July 11, 2008 Sounds like a cam position error code. Quote Link to comment Share on other sites More sharing options...
rfender Posted July 11, 2008 Author Share Posted July 11, 2008 OK. that would make sense. I just change the timing belt and water pump. Maybe the timing is off? I checked it several times to make sure. What do I need to do to fix it? Quote Link to comment Share on other sites More sharing options...
eatingupblacktop Posted July 12, 2008 Share Posted July 12, 2008 No. 1 cam position sensor signal. Test the sensor. Should read ~ 950 - 1250 ohms. Quote Link to comment Share on other sites More sharing options...
Chrissy Posted July 21, 2008 Share Posted July 21, 2008 Hi: My check engine light just came on. How did you find that code? Mine's a 96 LS400 with 97500 miles, which happens to be one of the checkup dates in the maintenance book - I thought maybe that may have trigger the check engine light. It just came on yesterday. Thanks? Christina Quote Link to comment Share on other sites More sharing options...
