jose martinez Posted October 8, 2010 Share Posted October 8, 2010 i HAVE A 99 LEXUS ES300. MY CHECK ENGINE LIGHT CAME ON AND I HAD THE CODE READ P0325. KNOCK SENSOR CIRCUITRY. I REPLACED THE KNOCK SENSOR 2 YEARS AGO WITH A DIIF CODE CANT REMEMBER IT NOW. THE LIGHT WILL BE ON FOR A DAY OR SO AND IT WILL GO AWAY FOR DAYS. DOES ANYONE KNOW WHAT THE PROBLEM COULD BE. ITS ALOT OF WORK TO CHANGE THE SENSOR AND THEY ARE 150 EACH. JUST WONDERING IF ANYONE HAD ANY INFO ON THIS? Quote Link to comment Share on other sites More sharing options...
