Toyota Engine PCM ECM ECU Computer 8966135570 ENGINE TRUCK Up for sale is a Working, in excellent condition Toyota Pickup truck ECU. My list shows this should fit many 1991 & some 1992 models with the 3VZ 6cyl 4X4 and an automatic transmission - the workhorse. This came out of a V6 4X4 auto trans federal emission model- quite a nice one! Typically the only thing that kills these trucks are rust, broken timing chains (belts on V6's) or electrical issues. Always keep a spare ECU, even if you don't need it. 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 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.
