i have a 2000 accord ex, 4 cylinder. my check engine light was on, i got it scanned from 3 mechanics. the same problem came out, the O2 sensor on top and bottom. i replaced it and reset the computer, still the light came on. we did another scan and it shows the top O2 sensor....any ideas??

 

Check your wiring all the way back to the computer. Put it on the scanner check you o2 voltage are you getting any at all. Possible CPU prob

 

i was thinking the same too. is there any website that shows me how to replace an computer or ecu?? where can i get them from??

 

The Computer is located behind the center of dash on the floor forward the floor console.Not to sure where u could get the CPU at or how much they cost.
