Nissan ECU 

A18-S31 ZH7K

  ECM ENGINE Up for sale is a Working, in excellent condition 1999 Nissan Maxima Engine fuel / engine control module. Part number – See the top or large photo. , This ECU came out of a 99 auto trans model, But my list shows this fits some other year models too, as nissan does not run these entirely by year- may fit some others too. As always your best bet is to match the part number to the one on your original ECU. These 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.
