924drb20

I have a 92 4dr honda civic with a b20 swap. Today when i started the car the CEL was on, so i check it, it tells me 27...FLASH (Long pause) FLASH (Long pause) flash flash flash flash flash flash flash. But if i turn car off then back on it will go away, then come back. I tryed to look up 27 but dosent seem to exist... I even tripled check what it flashed to me, only to read the same.

Any ideas this seems weird. Thanks

Did you ever figure this out? I'm getting the same code on my 88' Wagon RT that I'm switching to obd1. Anyones help would be much appreciated

Wrong forum.

You aren't having speedometer problems by chance, are you?

May be in the wrong section but after looking for quite sometime, this is the only topic I could find that was closest to my situation. Didn't want to make a new topic yet so I could avoid being riticualed there as well about not using the "search" button.

If it is to anyones help, I ended up figuring it out about 20 mins after posting this. While using my emulator on Crome I tested turning off various sensors and restarting the car, finally receiving no CEL after trying the oxygen sensor. I determined that it may have to do with my single wire O2 sensor for OBD0 oviously not responding to the volts that the OBD1 computer now sends.

The car has now been returned to OBD0 since this was only being done to test that once it's boosted and swiched over for good in the near future everything will work fine. It will be oviously tuned immediatly and have necessary in-car wideband and the factory sensor will be tossed.

Hopefully my information will help someone as hard on the search as I was last night :-)
