Diagnostic code P1406 on 2002 Mazda Tribute

My son's car has been running rough and the engine light is on. Acceleration is very sluggish. The diagnostic report is: P1406 - problem with differential pressure feedback sensor downstream hose is disconnected or blocked, have checked and no obvious thing found. Any ideas before we spend a heap of money fixing every other than the problem? Regards Sum
