ECM codes

Could someone post a link to a site that explains the codes-Not just what the codes mean but what flashes are for each code- Or just tell me what flashes go for each code..Thanks

I dont know of any sites, but each set of flashes represents a digit. Example: while the ECM is in diagnostic mode, when the check engine light flashes 4 times, pauses, and flashes 3 times, that means a code 43. The ECM will flash each code stored in its memory 3 times each.

Ok Thanks. There was a site becuase i got it from one of u guys up here before and just havent been able to find it again and havent had much time to look. Thanks for the information though.

ok i have code 24 wich is vehicle speed sensor. would anybody know were this is or what exactly this means.

What year is your car?

Cars with mechanical speedometers have the VSS mounted on the backside of the speedometer itself - you will have to pull the dash apart to get to it - newer cars with digital speedometers typically mount the VSS in or on the transmission.

A quick Q for you -

Does your speedometer work? If not, this is your VSS error.

It's an 86 caprice 305 5.0 and yes mechanical, i realy dont know if the speedo works i mean i havent driven it anywere since ive had it, no i take that back, i have driven it but it was night and at the time the fuse for the dash lights was blown (i didnt know it before i drove) so i couldnt see the speedo. I have driven it in the yard and it did register like 5mph but that was like way before i changed the computer and a ton of other stuff in it. Anyways as far as i can tell yes it works, so what else would be the problem with the VSS?
Thanks.
