Vacuum Hoses Diagram and VSV ???
Does any one know where I can find a vacuum hose diagram for a 91 Toyota Truck (4x4) 3.0?
I think I have a few hoses misconnected cause I am getting a 71 code (EGR)
My EGR valve is fine so is the vacuum modulator and coolant temp sensor.
I am not getting any vacuum to the EGR (cold or hot) so I need to trace back to the source of the vacuum. I thin it could be a faulty VSV or a hose misplaced in the wrong location. More so a misplaced vacuum line since my motor was taken out recently and the mechanic said he is not sure he placed back the vacuum hoses to the original place he removed them from.
By the way, out of the 4 valves that look like a VSV, which one is the VSV for the EGR? The color of the electrical harnesses are Blue, Red, Green, and Silver in that order from left to right (as looking on the passenger side).
