A buddy of mine has a 2004 Caravan. The OBD reading gave a code P0406 which is the EGR Flow Sensor A Circuit Low Input.
Is this sensor easily replaceable and if so any tips on how to replace it? ???

A code does not equate to replace.

What engine do you have (choices here are 2.4 4 cyl DOHC, 3.3 (flex fuel) or 3.8 V6)

Could be a vacuum line or dirty electrical connector.

Also this is covered under warrantee since emissions is covered up to 80,000 miles.
