Codes P0403 and P0406 - Replace The EGR Valve - Dodge Ram

Trivia question. Excessive EGR flow will increase MAP and cause negative fuel trim. Vacuum leak will increase MAP and cause positive fuel trim. Why is this?

fastest repair in the land !!
i have a 1999 durango 5.2L and the egr valve i swear is hiding like a little mouse, but after watching a couple vidoes and forums, i found that lil @#$%er...great vid E.O

Just got a P1404 on my Ram 1500, sadly its a 2012 4.7l so its on the back of the engine and I have to almost drop the engine to clean it.
Edit: it is intermittent, so most likely a bad connetion

This is probably a dumb question but I need to replace the egr valve on my 2005 Dodge Ram 1500 4.7 I assume it's basically the same concept as the 06 hemi ?

Its funny to watch your older videos, and see how you and your channel changed. You have always made great videos, but now you seem a lot more comfortable and natural.

Had P0406 on my 3.8 Grand Caravan....., all the wiring looked good. Changed the EGR valve, same type with the stepper motor. Not really sure if this one can be bench tested off the car. So I changed it with a Standard motor products replacement and it took care of the issue for over 10 thousand miles. Took a trip to the FLA keys last week from NY (highly recommended vacation spot) and about 20 hours into my trip as I entered the warmer climate the vehicle now threw a p0404. Based upon my research, these valves have a heat related problem with the internal circuit board. Unfortunately I dont have a Bi directional scan tool (Yet). Is there anyway that you know of that these valves can be tested off the vehicle? Its not the first dud that I have gotten with this kind of valve, but I would like to try and test it. Any input is greatly appreciated! Great videos and great channel!
Thanks Eric

The first thing I did after I purchased my wife her 2007 Dodge Ram Hemi, was to purchased a Diablo Tuner which also doubles as a Scan Tool. The first thing I learned about Dodge's was that just because a certain code appeared, didn't necessarily mean it was what was actually wrong.

Takes a grand total of 15 minutes to replace the EGR valve on a 5.7 Hemi.

Would like to comment on making more videos with failed Emissions, codes, and incomplete monitors.
Thanks Eric O.

is it the EGR valve that makes the throttle valve sooty? or is it the PCV valve or both? thanks...

good stuff, thanks...

Dear Santa,
that snap-on scan tool would look nice under my x-mas tree. :)

Old vacuum EGR's you can just push on the diaphragm to check the operation.  Now you need a bi-directional scan tool. :(

Great video !!
