IANO C

hey gang
my jap import 95 wrx is showing a fault code of 45.
after checking codes in the forums it points to a pressure sensor located just beside/under the boost solenoid.
my car has been suffering hesitations , slight backfire , problems with the car not moving anywhere when planting the accelerator car just acts like its missfiring and cut out problems , it cuts out sometimes.this is all most happening after the car reaches normal operating temperature.
my question is would a faulty/blown pressure sensor cause these symptoms.ive checked plugs , coilpacks , replaced throttle position sensor ,switched ecu all to no avail.now my cash is getting tight so has anyone experienced this sensor going to shed some light
thanx 4 any help
