BodybyFisher Posted August 6, 2006 Report Share Posted August 6, 2006 2002 deville. How do I extinguish this light? Found a "fried" rad tank 'low coolant level' sensor in the rad expansion tank. Also had message saying 'Low coolant level' replaced sensor and message has gone away but check engine light still "on" If you fixed the problem you can easily turn the check engine code off by disconnecting the battery for a minute.. In this link you can find how what the codes mean when you call them up: http://myweb.accessus.net/~090/dtcobd2.html You might want to check your codes to see if any are current...
