I've been having the same problem on my IS300 2001 for a month now. I took it in and the code was P1120. Now I need some clarification Pete. The picture that you showed is not the same for the part numer that Bill Shaft posted. Which one is it?The one on this picture is located where the throller cable is. Is this correct? To take this apart it seem that will take about half hour (being in the back).
