Yes you will have to hook it to a scan tool and erase the dtc or the light will stay on. sometimes you can unhook the battery for 30 sec or pull a fuse or turn the key on and off a couple of times

    then it is probably a loose connector or a coroded connection you might want to check that out

Is it a hard job to replace the egr vavle on a 2005 chrysler 300 3.5 engine

the egr valve can be changed from below but the left bolt must be done blindly by feel, (use a small mirror,) undue the 2 bolts and pull it out from the intake, careful to make sure the gasket on the end of the tube comes with it;
the 2 bolts that hold the egr on also has a metal gasket;
the hardest thing is to disconnect the electrical plug from below that connects the egr valve, - do not do this if you have no mech experience;

How to clean a egr valve from a 2000 mitsubishi montero. I replace the egr valve, but still engine ligth code 403 still on.

Your new EGR valve (assuming it wasn't defective out of the box), is fine, but the car's computer just needs to have its code 403 cleared. Even though you've corrected the problem, the computer will still light the "Check Engine" light, and store code 403 until the code is cleared using an OBD-II (On-Board Diagnostics 2) code scanner.
Note that the car will function perfectly with its new EGR valve, a lit "Check Engine" light and a code 403 stored. Its just a good idea to clear the code, so that then only NEW problems will become the reason that the "Check Engine" light gets lit.

What are the symptoms of a bad erg valve and where is it located on a 1999 dodge duranlgo

it is located at the rear of the engine behind the intake, the most common symptom on this is just a rough idle or in most cases a check engine light that stays on, no matter what is wrong with the valve it will set a fault code and turn the check engine light on, so unless the light is on the problem is not the EGR

I have a 99 Windstar 3.8L Keep getting DTC PO401 have replaced DPFE EGR Valve and EGR tube still keep getting Code PO401

Does the egr vavle open ? You will need to use a scanner to test the dpfe voltage when the egr valve is energized you should read around 3.5 4.00 volts. Also you could remove the vacume line from the egr valve and with the engine running you should see around 100 rpm drop in engine rpm at least this would indicate the egr valve is capable of flowing egr gases through the system to the cylinders.

There is a green tube coming off the side of my egr valve and it seems to be cut will replacing this tube solve my check engine problems

Hello Malcolm.
The vacuum line to the EGR will certainly cause your check engine light to come on.
The vacuum hoses on these cars become brittle with age, I generally replace broken lines with a quality rubber hose available at your local auto supply.
The check engine light may take a while to turn off without clearing service codes.
If the light is still on after a couple days of driving you may have other issues turning on the check engine light.
Hope your repair goes well for you.

EGR Valve

real easy. remove the top of the airfilter, then pull the bottome piece out. the egr vavle is on the engine with that tube going into it. there are 4 small bolts, 2 8mm for the tube, and 2 10mm to the head. should take about 10- 15 mins to replace. make sure the engine is cool.
