There is a very good search feature on this forum. give it a shot. I don't personally know what the codes are, but the search bar will tell you almost everything you need to know.

24 and 31 are both related to the VAF (24 is the intake air temp sensor, 31 is an open/short in the vane sensor). Most likely, the plug to the VAF is disconnected/damaged.

My books don't show one or mention one. What and where is that located? And any idea what the 3rd vsv on valve cover is for. My books only show 2 ? Thanks again for the help
