My Haynes manual doesn't have that one.  It seems to be in the ballpark of Exhaust Gas Recirculation (EGR).  According to http://www.allpar.com/fix/computer-codes.html, it is P0406 Exhaust Gas Recirculation Sensor A Circuit High. 
Hope that helps.

This sounds like a classic bad connection either at the battery or engine ground. Check and recheck all your connections and be sure they are clean and tight.

2005 Dodge Grand Caravan. Check engine light on displaying PO0406 any ideas? Code came up by cycling key on and off 3 times.


the PO406 code is the EGR position sensor.
I have heard tho that DMX corp had some issues with this code in the past where basically it was just tossing false codes. But they also did have a higher fail rate on them during 05-07, so you may have to replace it anyways.

Solution for


1st thing to do is have any codes stored in the cars computer read, this is important info. Go to any major parts store, they will plug a hand held scanner into the cars computer port under the dash, and retrieve any codes indicated by the eng. light being on (this is a free service at most stores). Write down the #'s and ask them to explain what's wrong and what they recommend. If you have any other questions, post the code #'s here and I'll help further.
