Hello, mattz604. Greetings from Russia.
I've searched thoroughly in the net, but still can't find an answer, maybe you could help.
There is one unidentified sensor on my 1992 3VZ-e, showed in the red frame on photo below.
It has single wire contact and vacuum line connection on the bottom (so I suppose it can't be knock sensor).
Could you please help to identify it?
Is it required for engine to work correctly?


P.S. Just if you ask what is the car - its a self-made trophy truck =)

Hey mattz604. I am restoring a 93 3VZE and am working on new head gaskets and want to do the EGR and Pair delete like you did removing the hard lines. My truck is a California truck 4wd and seems to have more vacuum lines than others do. Do you know where the idle up two hoses go? The 4WD has a vacuum hose I also dont know where to hook up. I removed the two PS hoses, and dont know if I have to cap some holes. I am waiting for the valve adjustment tool and then I can install the manifold to try to see what is left. The factory manual isnt much help. Thanks for the great write up. your engine bay is nice and clean.
