Does anyone know how to check for proper operation of the egr vacuum modulator gizmo that's attached to the firewall bracket next to all the relays?
I'm not sure if mine works or not and I'm getting a code 31. It appears that some circuit open/closes some sort of port that causes the vacuum line going to the EGR to have a varying pressure.
