Are you sure it wasn't a 43?

Clear the clodes and drive it for a day. Check again after that.

DTC 53 EGR flow test failure, it sets when the PCM tests the #1 solenoid and doesn't see the RPM drop it wants 8 out of 12 trys.

Check the wires.

I don't know why that'* not listed in the Techinfo articles. It'* in my FSM. Digital EGR valve on 93. Clean it and lightly oil it.
