17 short blinks, not 1 long 7 short, 17 consecutive short blinks, i have tested a couple different ECU's on it and the same thing no matter what ECU i use. the CEL comes on after you drive it for a bit......anyone? anyone?

 

VSS maybe?

Does your speedometer work?

 

Older ecu's do not have short blinks, just the str-8 ones. You are running a stock sohc ecu?

17 is the VSS speed sensor.

i am lookin right at the ECU man and i am telling you its 17 short blinks, one solid long blink and 7 short would be the VSS, this is 17 short, hell i will try to take a vid of it if i can and show you guys, the speedo works fine, never fails. That was the first thing i checked. its a stock crx Si ECU, both ECU's i have tested are CRX Si ECU's with no mods done to them and they both throw the same code......anyone?

 

That is the same code, the older ones only go to 20 or less so they are ALL short blinks. code 17 vss

I kinda thought that was what you ment, but riddle me this, why does the speedo work fine and never error out and i still get that code, the speedo in ED's is cable not electronic

 

The cable goes to the speedo. The speedo then sends a voltage signal to the ecu.
If your speedo is working while your driving and you get a CEL that would say your ecu is not getting the signal from the speedo. Meaning you have a short in the wire from the speedo tp the ecu. Make sense?

makes sense to me........just to clear something up, the 88-89 ecu doesnt have long blinks and the 90+ do?

 

All the crx civic ecu's I have seen have the short blinks. The b series ecu (b16a b18a) all have the longer and shorter.
