Toyota Engine PCM ECM ECU Computer  Denso Part 8966135890 /  175000-6010   3VZ

Up for sale is a Working, in excellent condition Toyota Pickup truck ECU. This removed from a recent crash damaged 94 Pickup 3VZ 5 speed. Unit is good used, and this truck still ran well.  Please match the part number from your original control unit to verify fitment!  This unit comes to you with a 30 day warranty from epartsland.

 It's good practice to always keep a spare ECU, even if you don't need it right now. See part numbers at the top of the listing. - . 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 trucks. these can also cause issues with erroneous check engine lights, idle control problems as well as emission control & cold or hot start problems. I have also seen fuel pump relay turn on faults (ECU won't turn on the fuel pump), as well as an condition where the high speed injector driver has failed. This causes the car to sit and idle fine, but it won't accelerate.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 back. 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.
