P0406 2007 DODGE CAROVAN, HOW DO I FIX IT

Answer 1

Hi there

This code is for the EGR position sensor circuit, high.

Most of the time the issue is carbon buildup on the egr valve itself. You can use carb cleaner to remove the carbon and it should help if it's the problem. A faulty egr temp sensor can also cause the same code. You should also check the egr port to make sure it's not plugged.
