Answer
Sandy,

The code is for the EGR solenoid.  It most probably should be replaced.  This is the exhaust gas recirculation solenoid that is for mixing exhaust gas back into the engine to cool the combustion chamber down.  Autozone or Checker can do a retest and sell you the part along with a new gasket.  Depending on your Nissan the job can be easy or difficult.  A Maxima would require the upper intake be removed to get to it.  Something with a four cylinder is much easier.  Anyway, email me back if you need more.
