code 327....

truck throwing a code 327 - egr valve circuit below minimum voltage.

i already replaced the dpfe sensor and the egr vaccum solinoid.

any other ideas?

i bought a new egr valve, but cant get the egr tube off the manifold.

i tested the egr valve with a vaccum pump it it is holding vaccum.

Is it possilby the electrical connector going to the switch? Maybe the little wires/blades are bent or dirty?

Straighten them and use a dielectric grease on them to make sure they are contacting.

If its not that.. maybe a ground or pinched wire.
