P0401 "egr insufficient flow" can indicate many things, including: 1-vacuum line plugged or leaking 2-pipe from exhaust to egr valve plugged 3-pipe to vacuum modulator valve from egr valve plugged 4-passages at egr are plugged 5-bad egr valve 6-bad EGR VACUUM MODULATOR VALVE I tried cleaning egr modulator valve, (beside/above egr)removed and tested egr vacuum & movement, inspected and cleaned all vacuum lines openings and pipes. All above did not work. I replaced the egr vacuum modulator valve. Light went out without a reset in about 30 miles of driving. Not sure if this valve can be cleaned. Retails for $69.US
the egr valve is sticking open and causing the motor to surge replace the egr valve and the problem will be solved
I've just cleaned the EGR valve on my 1999 Sebring Convertible. The EGR valve is over by the battery. Look from the front for something that resembles a thermostat.Old AnswerI have a 98 lxi V6. I believe the 3.0 liter is layed out in the same fashion. If it is, the valve is attached to the back of the intake plenum(the big silver thing that looks like 6 tubes stuck together) between the plenum and the firewall. Go to an autoparts store and buy a manual for the sebring. The directions are in there. That is how I did it. Hope this helps.

Specifically DTC P0401 is "Exhaust Gas Recirculation (EGR) Insufficient Flow". Now this is where we have to be careful when we read a code. In this case it is not saying the EGR valve is bad, it's saying the EGR flow is too low. Now it could be because the EGR valve is bad. Or it could be a clogged EGR tube or a broken vacuum line. This is why you have to be careful and check the whole system before you go changing parts. The PCM tests the EGR system during deceleration by momentarily commanding the EGR valve to open while monitoring the Manifold Absolute Pressure (MAP) sensor signal. When the EGR valve is opened, the PCM should see a proportional increase in MAP. If the expected increase in MAP is not seen, the PCM notes the amount of error that was detected and adjusts an internal fail counter towards a fail threshold level. When the fail counter exceeds the fail threshold level, the PCM will set DTC P0401. The number of test samples required to accomplish this may vary according to the amount of detected flow error. Normally, the PCM will only allow one EGR flow test sample to be taken during an ignition cycle. To aid in verifying a repair, the PCM allows twelve test samples during the first ignition cycle following a scan tool Clear Info or a battery disconnect. Between nine and twelve samples should be sufficient for the PCM to determine adequate EGR flow and pass the EGR test. To check the system first you need to remove the EGR valve and if it is clogged or broken. If it is, clean or replace it. If it is okay, then remove the EGR inlet tube from the exhaust manifold and the EGR outlet tube from the intake manifold. If either or both are clogged, clean them out or replace them. Then check the ports in the manifolds themselves to see if they are clogged. If so, clean them out. When you are done, disconnect the battery for about 30 seconds to clear the code and drive the car to see if the light comes back. This should take care of the problem. If not, then you will need to put a scan tool on the car and see what the EGR control system is doing wrong and correct it. The EGR Valve is located at the rear of the engine.

first buy one from somewhere then remove plastic covers disconnet negative battery cable then remove clamp then remove to bolts rear bolts are a pain in the assss then clean everything
i had the same problem when i smogged my truck and it is probaly two things the extenison connector to a little sensor on the passenger side fender wall next to the fire wall. just follow the vacuum lines from the egr valve. all it is an 2 inche extenison to a connector that can go bad from time to time and you really don't need it. just plug the sensor back in. the egr position valve sensor. the little plastic thing connect to the outside of the egr valve on the of the enginge to the rear. this part will run you around $30 - $45 dollars
could be the egr valve is dirty and needs to be cleaned. if there is soot build up, the valve may not close all the way which can cause a rough idle. if it ever stumbles while accelerating, that can be from it not opening when it should. cleaning it can be an easy 30 min job that anyone with basic mechanical skills can do. sometimes.
