Today I went to my Honda dealer, and they said my check engine was on because of a faulty ECU. They quoted $1400 for repair. Does anyone know where the ECU is located on a 2000 Honda Accord so I could get the part number and try to buy it cheaper? Any help is appreciated. Thanks.
Answer: It should be under the carpet on the front passenger side. Pull up the carpet and you will see a rectangular gold box. Unbolt it and then look on the side for the numbers. I think the number should start with a P.
