Mazda 626 MX6 ECU KLG3 18 881B  /  TN079700-7642

 Up for sale is a Working, in excellent condition Mazda 626 / MX-6 ECU. came out of a 97 626 4 cyl engine  -  may fit others too, compare your original part number, these are located in your center console., in front of your shiftier.  These are a frequent failure item in these cars because this is NOT a weather proof unit, and frequently takes on corrosive sugar & cigarette ashes due to it's location under the drink holder & ash tray.  Even aside from this high mileage failures can happen all on their own, with no damage from ashes or drinks.

 See part numbers at the top of the listing. This unit offers a 30 day functionality warranty. As always with this type of component your best bet is to match the part number to the one on your original ECU. 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. 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 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.
