sensation Posted August 5, 2011 Share Posted August 5, 2011 I have a Lexus RX300 1999, 4WD. I had a Check Engine light on my dashboard. When scanned, it says its the KNOCK SENSORS (2), so I changed both of them at the garage. The check enginge light came back after 10 minutes of driving. After another scan, it reveals that its still the knock sensors. I dont know what to do. Anyone has an idea? Quote Link to comment Share on other sites More sharing options...
lenore Posted August 5, 2011 Share Posted August 5, 2011 When they changed them did they look at the wiring harness? Some have reported that the harness was brittle and the insulation was shorting out..... Quote Link to comment Share on other sites More sharing options...
