simple CEL question
You guys know how the Check Engine light comes on then goes off when you turn on the ignition?
Well, if it stays on, then does that mean the ECU is fucked?

Re: simple CEL question (senpai)
solved, it was the ecu.
when you put the car into ignition, the CEL comes on for a few sec and then turns off. Well this one stays on.
My brother has a 93 LX, obd1 p06. So I swap ECUs just to verify and now the CEL does turn off.
Wish I could have figured this out earlier.

Well atleast you know what you did. This thread was pointless and non informative (sp?) It had nothing for us to help you or you to help us. You just thought it was your ecu from the whole time and asked us if it was. Ehh atleast you fixed your problem.

I disagree, the next person will now know that it's their ECU (or some major wiring issues) if the Check Engine Light doesn't turn off.
I've never had a bad ECU, so this is my first experience; something some others may experience as well.

Re: simple CEL question (Luserkid)
Just because the CEL didn't come on with the other ECU in there doesn't mean anything. You still should have pulled the code. ECU"s don"go bad" unless you've fucked with it somehow.
When you disconnect an ECU. you wipe out the memory of any trouble codes it may have stored. It will usually take a few drive cycles for the info from whatever sensor is malfunctioning to report back to the ECU. I'm willing to bet that if you left that ECU in for a hundred miles or so, that CEL will come back.
I speak from my experiences last week. Just something to think about.
I don't know why people have such a hard time reading codes.....if you can't figure out how to jump the trouble port on the ecu and count the blinks, you can at least go to Autozone and borrow the OBD scanner. They always just hand it to me and I go out to the car, plug it in and 10 seconds later I know exactly what the problem is. You can also clear the code without resetting the whole ECU
