I have the following error codes on my 2003 dodge grand caravan: Sof 5.0 E 100.7 E 400.1 WHAT DO THESE MEAN?

SOURCE: Engine light on in 2000

it is your EGR Valve. EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve
, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.

Causes A code P0401 most likely means one or more of the following has happened:

• The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
• There is a blockage in the EGR (tube), most likely carbon buildup
• The EGR valve is faulty
• The EGR valve may not be opening due to a lack of vaccuum

• Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
• Clean out the EGR valve and/or tubing to remove deposits
• Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
• Replace the DPFE sensor (with a good quality / OEM one)
• Replace the EGR valve

You can get free owners manuals online at:

http://www.edmunds.com/ownership/howto/articles/120189/article.html

or just type "owners manuals" in your search.

Here is a post I found that worked for my 2005 caravan.

For a 2001 Dodge Caravan: The owner's manual is vague, only stating that all fuses are under the hood in the fuse box, no diagrams. Once you have removed the fusebox cover, the diagrams for what each fuse does is provided under the lid. UNCLEARLY marked is the radio fuse, a 20amp fuse located 2nd row from top to the right of the accessory relay. It is marked: RDO/IP IGN.
