Nissan ECU  A56T64ZP5    ECM ECU PCM ENGINE CONTROL

Up for sale is a Working, in excellent condition 2003 Nissan Maxima Engine fuel / engine control module.  Removed from a recent crash damaged 2003 model year i30.  
INFINITI I35 03 (under console, AT)
MAXIMA 03 Elec Cont Unit (ECU); (under console), AT, w/trac cont (TCS)

We were able to start and "lot test" this car, and the ECU works fine.  Part number at top - See the top or large photo.  Nissan does not run these entirely by year- may fit some 2002 models too models & others too.   As always your best bet is to match the part number to the one on your original ECU as there are several variants you may have, even inside of this year range depending on options & accessories. 

Note, these units commonly have problems related to the throttle and idle control system, and if you are having these problems it is important that the issues that caused your ECU failure to happen in the first place are corrected first.  These units we sell are always internally inspected for this fault  and are GOOD.  These units also need to be initialized to your car before it will start with this ECU, which will need to be done by a technician with access to the proper factory equipment.  If you are having issues with your Maxima car that are requiring you to replace your ECU, get a good used unit.  Buying this here is going to save you about $1000 off this repair, as the ECU is the most expensive element of the repair!!

***!!!RARE ECU ALERT!!!***

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.  These are mounted in the center console, positioned toward the firewall.

Price one of these new, and you will be shocked at the price.  You can save over 80% with us by buying a good used unit!  This unit removed from a crash damaged lower mileage car, and comes with a 30 day functionality warranty.
