P0400 1999 Nissan Altima Sedan -egr solenoid connector will not separate, could it be damaged

Question

Trying to r/r egr solenoid p0400 but can't get electrical comnector off the harness. Could it be shorted or melted

Answer 1

HI there,

It's possible the connector could be melted. It's also possible the actual issue is the vacuum line for the egr is causing the issue or a plugged egr tube. The connector is water tight, the green portion pushes down into the connector to release it.
