Toyota Engine PCM ECM ECU Computer 8966128320  175000-6151

Up for sale is a Working, in excellent condition Toyota Previa Minivan ECU. My list shows this should fit many 1991 1992 & 1993 1994 and 1995 models with the 2.4 Liter NON supercharged 4cyl & automatic transmission and 4 wheel drive. See part numbers at the top of the listing and compare this with your original. These unit asside from high mileage related failures, frequently become damaged due to corrosion.  Due to their location (under the drive side seat) they tend to get moisture and salt accumulate build up, which encroaches into the ECM destroying the circuit board.

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.
