Part number is listed at the top or in the large picture. Compare this wit your original unit to be sure if this will fit your car. This was removed from a 01 Sentra SE 2.0L with automatic transmission and without security
This unit was removed from a car that was recently crash-damaged and still ran. 
These units are frequently damaged in this model by faulty ignition coils, and faulty idle control valves.  When these units fail they are known to short circuit and this in turn cooks these control units, causing total failure.  This ECU is known good!  Before installing this you MUST replace all 4 of your ignition coils with OEM new units, and you must also replace your idle control valve.  If you do NOT do this and you simply plug this ECU in it will very likely kill this one too.  This model range is known for this problem, because of this, this control unit comes to you as-is, no refunds.  As soon as it gets plugged into your car, you own it.  We have had too many problems with this model range, sending good used units, people NOT replacing what's wrong, and returning an ecu they destroyed.
A faulty ECU can cause problems ranging from a bad idle control circuit to random no injector pulse signal, no-spark, (causes no start or random cut outs) & many others. These are extremely expensive to buy new.
