EGR Load Control (WOT) Valve
- This valve dumps EGR vacuum to the atmosphere at or near full throttle. With engine running at normal temperature, set throttle on kickdown step (high cam). Connect vacuum gauge to EGR side of WOT valve.
- Apply a minimum of 6 in. Hg vacuum to WOT valve port "C". See Fig 1
. Gauge should drop to zero. If not, replace valve. Adjust WOT valve so vacuum applied by hand pump will drop when near WOT.
