Hello, its been quite a while since I have been here, but I need to see if anyone knows where the ecm is located on my 91 ES? I have tried to find the info on Google and here with no luck.
thank you

Inside the car direct center by the firewall. Pull the carpet back on both sides you'll see it, held in by two 10mm bolts.

Hi Lex91,

I would assume that it is in the same location as the 1988 - 1991 Camry, which is under the dash in the middle section.

Here are some instructions from a Toyota forum on how to get to it:

Here is a diagram:



Here is another diagram:


Hope this helps.

EDIT: Confirmed by Lexus2000's post.

I found it thank you!

Why do you want to remove it?

Lex91

Well, because of the weird things the car is doing that would have pointed to a tune up or o2 sensor but everything has been replaced which leads me to believe that the computer might be going out.

I've never seen one go bad but it is possible. Oddly enough the ES250 ECU is not the same part number as used in the Camry.

From what I read its possible but Im not sure what else it could be so I have to start there i guess. I did find one on eBay for 34.00 tho
