i need to see a diagram for a 2010 dodge grand caravan with a 3.3 liter It has air condtion

CODE PO406 EGR POSITION SENSOR CIRCUIT HIGH INPUT.

The po406 is an egr code which is common for a bad egr valve, but check your wiring and check for plugged port or carbon lodged in valve, as far as the p1561 this is not a good code, this must of been gotten with a genric scan tool, i would fix the po406 and then reset the computer readiness monitors and drive it and go from there. hope this helps, good luck

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.

check fuses and relay to fan, if not it, check wiring to fans.
