You'll need to change out the EGR Valve. The P0406 is the sign of a failed
EGR Valve. The EGR valve is easily accessible but be warned about the
bottom 10mm bolt on the valve. It's a tight fit next to the alternator and
the molded in washer will hit one of the ribs on the alternator itself (on
the way out and on the way in). Use a thin 10mm deep (1/4" drive) and you
won't have any problems. 10mm and 8mm is all you need to swap it out.

Subject: DML: O.T. 05 Grand Caravan
When it rains it pours. First my 14 YO son got in a solo bicycle wreck a
month ago and brok his back in 5 places and ended up needing emergency
surgery to restore nerve function in his legs. He's doing much better now
and walking again. Then we discovered the right front fork seal on my
motorcycle was leaking and my battery is shot. Then we find out my wife's
motorcycle needs a new starter. Now my wife's 05 Grand Caravan threw a CHECK
ENGINE light this afternoon. I got out my trusty scanner and it read only 1
code, P0406, EGR Flow Sensor A Circuit High Input. I cleared the code but it
came back within 3 miles of driving. The van has about 66K miles on it and
so far has been a good vehicle. Anybody got any ideas on what I need to do
to fix this? EGR valve or sensor I can change relatively inexpensively? And
if so, where are the parts located on the engine? Bernd? Any help would be
appreciated.
Thanks,
Ray Irons
