SOURCE: P1404 error code
The PCM monitors the exhaust gas recirculation (EGR) valve pintle position input to ensure that the valve responds properly to commands from the PCM. When the ignition switch is turned ON, the PCM learns the EGR learned minimum position. The PCM compares the EGR learned minimum position to the EGR position sensor when the EGR valve is commanded closed. If the EGR position sensor indicates that the EGR valve is still open when the PCM is commanding the EGR valve closed, this DTC will set.
Excess deposits on the EGR valve pintle or seat--Remove the EGR valve and check for deposits that may interfere with the EGR valve pintle extending completely or cause the pintle to stick.
Usually this will fix it but in some cases you may have to replace the egr valve.

the purge valve i believe is located near your gas tank unless theyve moved it i should look like a little canister cyclinder shaped. both codes could be set off by the same problem. try replacing the valve.

there are a couple of things, first make sure there are not restriction in the exhaust, i know the dealer has had to replace converters under warranty because of this problem, then theres a reflesh program for the computer due to this problem, and lastly,run with egr off make sure it clean of carbon,carbon gets stuck in pintle sets check eng lightbut carbon then blows by so when you remove egr you see nothing, well start with these good luck.
