Replacing parts on the chance of solving the problem can get expensive. Take it to someone who has a scanner tool to check the sensors. Sound like you have a sensor not working.

Have a po405 code on a 02 impala, said its a egr


In Hopes the info BELOW will Help, And Also the Mass Air Flow Sensor is A Totaly Different Sensor (MAF) The EGR Valve Code you are asking About is More Related to the Exhaust Gas that the EGR Valve is Allowing to Flow Past Its Self. I can tell you that From My Own Experience that EGR Valves Get Dirty More than they Fail and Require a Simple Removal and Cleaning of Carbon Buildup. This is after the Procedure Below is Performed.

CIRCUIT DESCRIPTION
The powertrain control module (PCM) monitors the exhaust gas recirculation (EGR) valve pintle position input to ensure that the valve responds properly to commands from the PCM and to detect a fault if the pintle position sensor circuit is open or shorted. If the PCM detect an excessively low EGR Position sensor signal voltage, this diagnostic trouble code (DTC) will set.

CONDITIONS FOR RUNNING THE DTC
The system voltage is greater than 10 volts .

CONDITIONS FOR SETTING THE DTC
  • The EGR Position sensor is less than 0.14 volts at any time.
  • The condition is present for more than 20 seconds .
ACTION TAKEN WHEN THE DTC SETS
  • The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle in which the diagnostic runs and fails.
  • The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
  • The PCM disables the EGR valve for the ignition cycle.

Insufficient egr flow, already replaced egr valve and purge valve canister


I too replaced the egr valve and was discouraged that the check engine light came back on with the same "insufficient flow" code. I took it to my mechanic to put it on the monster diagnostic machine. It said "check all vacuum line, and or map sensor". After looking real close we found a melted vacuum tube, and a cracked vacuum angle connector. Replaced both vacuum pieces, reset the codes, and good to go. If that fails than the next thing is the map sensor, that tells the EGR valve what to do.
