Nissan ECU Up for sale is a Working, in excellent condition Nissan Sentra / 200SX Engine fuel / engine control module. My list shows this fits 1996, however this may also fit early & late 1995 as well as 1997 models. Part number is listed at the top or in the large picture. As always your best bet is to match the part number to the one on your original ECU. These units have been NLA for quite a while now, and are not at all easy to find, at any price much less as fair as this. These are usually fairly reliable, however can easily be damaged by wiring faults or voltage spikes (caused by a faulty alternator). A faulty ECU can cause problems ranging from a bad idle control circuit to random no injector pulse signal (causes no start or random cut outs) & many others. These are extremely expensive to buy new.
