I tested the VSV for turbocharging pressure control on a 1HD-FTE engine as per instructions in the Toyota repair manual RM617E, see below, in step 4 (inspect VSV operation) check that air does not flow from port E to G.
1) Can you please confirm that a VSV valve is NOT operational (useless) if air flows form port E to G and that I need to replace this VSV valve.
