Ok I was driving to work and my Check Engine light goes on. It is not any of my fluids so I dont know what it is. I pulled back the carpet and turned the key and this is what I got.

Beep ..................... Beep..Beep..Beep..Beep..Beep..Beep..Beep..Beep..Be ep..Beep..Beep..Beep..Beep..Beep..Beep.Beep

So one beep then space for about 1 sec then 16 beeps in about .5 sec intervals. Now I have never read my ECU before but my understanding is that the 1st beep with the long space after it = 10, then each other little one = 1. Is this right?

So am I looking at a code 26 here? Or am I looking at a 17? Because I thought that Honda ECUs only went up to 20. Maybe 16? I dont know help me.

Thanks

So when it goes blink one time and then a break that means that there are more than one code showing at the same time? Ok so I had one blink then a break. Then I had 16 in a row. Damn it! I dont have any money to replace this ****! Looks like Im doing a DPFI to MPFI swap and have to find a DX 02 Sensor. I can get this sensor from any 88-91 Honda DX or DPFI engine right? Like from HBs, Sedans, CRXs, wagons etc.

Code 01 = Oxygen content
Code 16 = Fuel injector

yeah.. I've got out the code bible, and it says that you're throwing an oxygen sensor code... check to see if it's tight... and a 16 is a fuel injector... you guys were right on. They could be related.... you can reset them by removing the Hazard fuse for 10 sec.

oh yeah, 17 is a faulty speed sensor...

also, pull the negative cable off the battery, wait 10secs then put it back on. it could just be that the ecu needs to be reset.
the weird thing, when i first put my engine back in (d15b2, same as yours) i was getting the same 2 codes. code 1 reset when i reset the ecu. and code 16, my cold start injector wire was a bit loose.
