Default ECU Throwing Code 19: Automatic transmission lockup control valve

What does that mean? My transmission's not even automatic! I'm completely lost. Any help appreciated.

Wow, I have the same problem. I hate it and I just ordered a P28 ECU chipped with Hondata S300 hoping it would fix the problem. Idk, bump this up so we can figure out what the hell is going on with this...

being chipped isnt going to help you you have to do a auto to man conversion inside the ecu ...kinda like chipping but not

im shure theres a writup somewhere if your down with soldering if not i reccomend having it done for you or finding a man ecu...dont just look at the sticker on the case look on the accual pcb so you know it wasnet just switched

No, what I did was I ordered a new ECU completely. I really didn't feel like going through all of the trouble of chipping it myself. My ECU code is 37820-P30-900. I don't know what that means, but I'm sure someone does...

If I recall correctly, p28 ecu's made for automatic transmissions are equipped with a resistor sitting underneath the ROM. I remember reading (a few years ago) that this resistor has to be removed and the nodes that connected it shorted in order to avoid Code 19 in a manual car.

Is this correct? If so, does anyone know the resistor that needs to be removed?
