97 Series 80 Land cruiser with 350k miles.
got this code a couple of days ago. I had replaced all the small vacuum hoses as part of baseline, but there was some larger diameter hoses that were not replaced. After replacing the 7mm? Hose between the VSV and the EGR, and 50 or so miles of driving, the check engine light has gone out.

With 350k miles, I will take off and clean the EGR in the near future
