guciol Posted August 13, 2008 Share Posted August 13, 2008 Hi all, Recently I bought a 2006 GS300. Today I got a check engine light go on, an exclamation point in a circle (dont know what is the professional word for that light), and a traction control light came up. I ran a scan on the car and got a P0456 code. The code means that it is a Evaporative Emission System Leak Detected (small leak). I am wondering if anybody else had this problem. Any advice is greatly appreciated. Luke Quote Link to comment Share on other sites More sharing options...
