P0405 Exhaust Gas Recirculation (EGR) Position Sensor Circuit Low Voltage
There may be no symptoms of a P0404 DTC other than the MIL (malfunction indicator lamp) or check engine light. However, Exhaust Gas Recirculation systems are inherently problematic due to carbon buildup in the intake manifold, etc. This normal buildup can lodge in an EGR valve, holding it open when it should be closed. If this is the case, the engine may idle rough, or not at all. If the valve has failed and is NOT opening, then symptoms would be higher combustion temps and as a result, higher Nox emissions. But the latter symptoms aren't going to be noticeable to a driver.

The pcm will turn light off within a few days after egr valve replacement if the egr valve was the reason for the po405 code being set. Give it a few days and see. i f not then there may be a problem with carbon buildup under the egr valve in the cylinder head
