Up for sale is a Working, in excellent condition Nissan Sentra Engine fuel / engine control module. 

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 unit was removed from a car that was recently crash-damaged and still ran.  I have several of these that are the exact same part numbers, some look a little different (stickerage) but are the same part number.  These are bought by the part number!

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.
