To answer your question, the sensor is on the firewall, 3 pin conductor and the Solenoid is on the EGR pipe with 6 pins. Their name is nearly the same; EGR Boost Sensor vs EGR boost sensor Solenoid.

P2228 says if Terminal 34 of the ECM is 0.35V or less all the time it will be triggered.

EGR boost sensor failure
Open circuit between EGR Terminal C and PCM terminal 90
Open circuit between EGR Terminal A and PCM terminal 34
Short to GND circuit between EGR boost sensor Terminal A and PCM terminal 34.

A - 34
B - 91
C - 90
