generally on an accord of that age, the S blinks because it is telling you your car is S-LOW hehe just kidding, its probably a speed sensor

The 'S' light is kinda like a check-engine light, but for your tranny. Look around for instructions for pulling CEL error codes, for your year (not the same as my '98). Post back with the codes.
If you jumper a connection & watch the light blinking, then your 'S' light will blink its own code while the CEL is blinking its code.

If you simply peel back the carpet & watch the flashing LED, then you have to find both the engine ECM & the transmission TCM & watch both their flashing LEDs.

I know you found instructions about jumpering, but I sorta thought that setup was newer than 1991. Make sure you look for the proper year.

If '91 has the wire-jumper thing...
Find the proper wire (this is the part I can't really help since I don't have a '91).
Bend a paperclip into a 'U' shape, put it into the plug.
Turn ignition on.
Watch the CEL & 'S' lights flashing.

CEL code 5 is manifold pressure is higher or lower than expected. But that's from my '98 Helm book, I didn't think '91 had that code. Who's got a '91 Helm book?
I don't know about your tranny codes, they don't match my list, but who knows what's different '91 vs. '98??

It would be the intake manifold. For my '98, that means the MAP sensor reading is inconsistent with all the other sensors & the operating conditions of the engine. I didn't think '91 had that much software cross-checking all the sensors against each other. That kinda stuff is why OBD-2 cars have so many sensors. Redundant measurements.

That doesn't make sense. Can you check the code again? Remember that between codes there is a long pause, about 3 seconds. Start after that. There may be more than one code. They will keep repeating.

If your sure about that, your TCU must be f-ed up. Long blinks always come first.

The way you're describing it, the first code is one short blink. Tranny code 1 (in 1998...!) occurs together with CEL code 70, it means the lock-up clutch can't engage/disengage & it's stuck in 4th. I don't know what it mean in 1991.
But then you say it's a short blink followed by a long one. Is there another long pause between these 2? If so, then you've got 3 codes. Code 1; repeated code 1; & code 10. My list doesn't have any tranny code 10.

I bet 'How-to-fix-it' would be pretty specific to your year. Gotta get your hands on a Helm manual.
Generally, once you have the code, you still have some diagnosis for exactly which component is broken. As far as the TCM throwing error codes, it can't tell the difference between a bad control solenoid or disconnected wiring.

IVE SEEN POSTS FOR THIS TOPIC, I KNOW SOME PEOPLE GOT INFO ON THIS...
HELP ME OUT SOMEONE

Ok, let's start over. I see a dozen copy and pasted posts, but don't know which are yours, and half of them date back to 2002. So that isn't really a help. I don't know which are yours and which are someone else's problem. So for starters here's the info we need to know:


1) Did this just start or has it been going on for years
2) Did you already try pulling codes and swapping the TCU or was that someone else?
3) If you searched, the flashing 'S' light either refers to a busted TCU/TCM (tranny control module/unit) or a busted VSS (vehicle speed sensor). You mentioned the speedo works fine...so I'm assuming your cruise control and tach work fine as well...if this is the case it probably isn't the VSS and is most likely the TCU.

So did you replace it with another TCU and was this one from a junkyard...if so it is possible you got another busted one. I just typed all this up in another link here:

http://www.automotiveforums.com/vbulletin/showthread.php?t=409559


Lastly, if you need/want to pull the code, here is all the info you could possibly want/need:


To learn how to pull your own codes, go here and read everything:
http://www.hondapitstop.com/accord/technotes1/engine/error_codes/error_codes.html

If for some reason that isn’t sufficient for you, you may want to look at this:
http://www.automotiveforums.com/vbulletin/showthread.php?t=19102&highlight=P1259+VTEC+system+malfunction

Now you should have a code…and you probably want to know what the code means, so check out these pages. Between these 4 pages you will DEFINANTLY find your code and what part of the car it refers to.

Now I hope something in there is new/helpful. Please let us know what you exactly have and have not done, and try what I just posted, and if that doesn't work, we can go from there.

Had that problem on a 90 Lx auto. Turned out to be the speed sensor, pretty cheap, had a mechanic do it. Sooner or later the speedo will stop working, pretty frightening doing 70 down the freeway. Good luck!

As I wrote above, the blinking 'S' light can be either the speed sensor or TCU. In his case, I think it's the TCU.
