Re: EGR Vacuum Switch help

Does it have to be exact replacement?

Can you measure the voltage coming from the ECM when the circuit is active, and substitute a different switch/solenoid that operates at that voltage?

All this gizmo does is allow vacuum to pass to the diaphragm in the EGR valve when voltage is applied to the gizmo, right?
