2003 Nissan Frontier Pickup ECU ECM Engine Control Unit Computer MEC07 450 C1 - Recent take off from an insurance totaled crash damaged truck

See part numbers at the top of the listing and compare this with your original. As always with this type of component your best bet is to match the part number to the one on your original ECU. Should fit these models, though please check you original part number!fits many 2003 models with the 3.3 liter V6 

This unit offers a 30 day functionality warranty. A faulty ECU is one of the most common no start or random stalling problems with these cars. These can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. If your car does not have these issues but you intend to keep it a while, I recommend our customers keep an extra ECU in the trunk. These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and you can never find one when you need one. Even now finding a good one second hand is getting to be quite difficult as these cars get older.

This unit was recently removed from a crashed damaged insurance totaled vehicle.
