Re: OBD II Location?????
right near the sassoflange...
no, for real you haven't got an OBD II. also it's not really called and OBD II so much as that is just the type of ECU one might have. 93 accord=OBD I ECU. 96 and later=OBD II ECU. brace for flaming... |
Re: OBD II Location?????
ok where can I find the OBD I ECU? THANKS!!
|
Re: OBD II Location?????
it's under the front passenger carpet. pull back from the firewall, you'll see a stamped-steel plate held down with several 10mm nuts. the ECU (and transmission computer if automatic) is bolted to the backside of this plate. once the plate is unbolted from the floor, you can flip it to access the ECU. you may need to unplug a few of the wire connectors to allow it to flip.

Re: OBD II Location?????
Wtf are you trying to do?
Are you trying to get access to the ECU - which is the computer itself, or are you trying to check the codes? |

Re: OBD II Location?????
Just pull the ECU fuse.
|
Re: OBD II Location?????
isnt that in the fuse box and woudnt u need the ecu to be connected? sounds important!
|
Re: OBD II Location?????
Well yes, it's what gives the ECU power, remove the fuse, remove the power, clears the codes. You insert the fuse back in after a few minutes.

Re: OBD II Location?????
ya i removed the ecu fuse and the power and put them back in after a few min and nothing changed, the light still comes on! any other ticks would be great THANKS!

And to reset the ECU and clear codes, you have to pull the hazard/backup fuse, which will also reset your clock and radio code if equipped with an anti-theft radio. |
Re: OBD II Location?????
well i had to fix the o2 sensor and i think my brother ****ed with it wich cauesd the light to turn on but u telln me to unplug the hazardbackup fuse and it will reset????
|
Re: OBD II Location?????
Is the CEL throwing the same code as before? I completely forgot about what Targa mentioned. If you don't fix the code, it won't clear it'll just be right there.
And what brand O2 did you get, some brands work better than others. |

Re: OBD II Location?????
Jesus Christ, this thread makes my head want to explode!
How to check codes https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/how-pull-cel-d4-srs-abs-codes-code-lists-1901557/ Find out what code you are getting and then fix it. Dont just "turn the light off", its there for a reason |
Re: OBD II Location?????
uh no thank u ill try 2 clear the code! sense its not a major problem! if i new it was a major problem i would fix it!
|
Re: OBD II Location?????
It's a pretty "major" problem for a closed loop electronic fuel injection system to be completely missing a primary oxygen sensor. It's just going to run in open loop constantly.
If the sensor is MIA, then no amount of pulling fuses will clear the code. It's going to come back immediately as soon as you turn the car on. |
Re: OBD II Location?????
idk anymore! how do u go about fixn o2 sensors????
|
Re: OBD II Location?????
I think YOU need to take it somewhere and get it fixed, since it sounds like you have no idea what is going on
|
Re: OBD II Location?????
obviously. thats why i posted this up!
|
Re: OBD II Location?????
You wire the O2 sensor back in it's place...then no more CEL
|
Re: OBD II Location?????
If you want to troubleshoot the O2 electrical connections. Then I would suggest you get yourself a manual. If you don't have the electrical know how or tools to trouble shoot. Then you could just replace the primary O2 sensor. All you need is a big wrench and a new O2 sensor.
I don't have the manual for the 4th gen Accord all in one PDF yet. Otherwise I would send it too you. Try searching for 91-93 Accord manuals on Google. you may get lucky and find one that you can download free of charge. :thumbup: I know that they are out there but we aren't allowed to post links to them on this forum. good luck :beer: |
