So does it perform the RC Valve tests without the motor running OK? (With a healthy PGM!)

IGN off >> kill switch off >> unplug T.P.S. >> IGN on >> kill switch on: RC Valve opens.

IGN off >> kill switch off >> connect T.P.S. >> IGN on >> kill switch on: RC Valve closes.

This would indicate the servo and RC Valve operation is OK - in test mode, at least!
