Code 9 is the countershaft sensor - which is the two wires from your pic.

Again, there are two sensors on the psss end of the trans. You need to locate them trace the wires back to the connector and note the color of the wires that are connected to them - see pic in post #21.

I'm "guessing" two or three of the connectors have been switched. So you are going to need to check the wires to them and see which ones have been switched and get that corrected.

Trust me, I HATE wire issues...but over time I had to get over that to get things going. Sometimes they can be simple other times you just want to throw in the towel......recent example for me, 97 Accord kept throwing a lock up code....clear it and it would come back in a day, a week or maybe a month. Pull it, clean it, test it and still the same thing. Finally one day I'm staring at the dang thing trying to think of what to do........I notice the wire clip that holds the wires to another harness was broken, alowing the wires to "move around" a lot. I zip tied them to the haness and it has now been four months since the code has come back

So I ripped out the wires to the countershaft sensor, that explains it all. And the countershaft sensor plugs into the connecter on the passenger side fender, the one I posted a pic of? So if that's the case, the countershaft sensor must have a female connector because that connector on the fender is a male.

So if this is the correct diagram:


Then this is the wire from the mainshaft sensor:

So in that case, what plugs into the mainshaft sensor? Or the mainshaft sensor plugs into what?

I attached a pic of the location of the countershaft sensor on the transmission. You will have to start at the sensor and trace the wiring.

Go to the common diy thread mentioned earlier. Click on online shop manuals link. Open the hondatech link. Open the accord folder. There is a 93 accord shop manual you can download that will definitely help. It may be for a non-us accord, but they will be very similar.

So I've found the main and countershaft sensors. Now just to trace the wire on the mainshaft sensor. Seems like it goes down into the abyss. And now to figure out what plugs into the connected on the mainshaft sensor.

Well maybe not. On this countershaft sensor, right next to the fuel filter, it has two rivets in it rather than a 6mm bolt. So am I looking at something else?

Update:
I cannot find the countershaft sensor to save my life. Mainshaft is no problem. I've looked through the manuals and diagrams, can't find the damn thing. And one more thing, could someone please tell me what the mainshaft sensor connector is supposed to plug into? Do both sensors plug into each other or what? I know I ripped out whatever was plugged into the mainshaft connector, which accord to poorman was the wires from the counter shaft (based on color). So in that case, both the mainshaft and countershaft sensors mount into the trans and then the wires from each sensor connect to each other via the male/female connectors?

Update:
Think I found the countershaft sensor


It's down below the trans dipstick.

I didn't touch that thing. Didn't even come close to it, it's still plugged in and fine. So it can't be that. What are the chances that I have a faulty vss to blame for all of these problems? But that still doesn't explain what connects to the mainshaft sensor. It has the be the vss.

Taking pics from further back will help us figure out what you are looking at.

Since you have no VSS code, assume the VSS is not the problem.

None of these wires should tie into each other. Each sensor should have its own wire to send signal to the transmission computer.

Here is a picture I found of the speed sensors. The VSS is on the left, and the countershaft sensor is on the right (I think). I never owned an accord with an automatic transmission.

One thing I can say for certain is that I ripped out whatever was attached to ether the mainshaft or countershaft sensor. Must be the countershaft considering my tcu code. So I ripped some wires out. Serious repair? Or should I say expensive repair?

It may be a very simple repair.

In post #20, you showed one end of the wires. What does the other end look like?

I don't even know where that wire is anymore. And I'm not sure what it looks like because the wires were in a sleeve way back where I couldn't reach or see

Have you located the countershaft sensor?

The ends shown in that picture could easily be plugged into the plastic electrical connector. You would have to do some searching to find where the other end connects.

Option 1. If you can find those wires you removed, then the repair would be relatively simple. FYI, always keep that kind of stuff when you go in to do a repair.

Option 2: Go to a u-pull-it junkyard to find the harness (or section you need).

Option 3: Run wires from the countershaft sensor to the transmission computer. Splice into both spots.

I believe I've found both sensors unless there's more I don't know about. The pevious picture I posted, right below the trans dip stick, you have to take the splash guard off to get to it.

You can see the yellow dipstick up there.

And the other sensor is right below that, right above the passenger tire. Both on passenger side. They both look like sensor heads, very similar looking with one bolt holding them on. You can see the fender of the car. The trans drain bolt is right below

I know it would help to take pictures further away. I'll do that tomorrow. im just trying to describe what you're seeing there.
