2002 Mazda Tribute Question: Diagnostic code P1406

 

Question

Summercity, 3.0L V6, Wake Island, HI, April 16, 2013, 21:44
 Rookie

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

    DPFE sensors common problem, same part used on Ford! Bout 30.00 @ NAPA. Be sure not to get hoses crossed.
