EGR Load Control (WOT) Valve

This valve dumps EGR vacuum at or near wide open throttle. This valve senses venturi vacuum at a predetermined level and causes the EGR valve to close. When engine load is then reduced from wide open throttle, the EGR load control valve closes and completes the vacuum pathway to the EGR.
