Engine cut out while riding, error code 19

thanks for your replies!

I was tempted to fiddle with the connections but decided to just send the bike to yamaha instead.

they hooked it up to the computer and after some testing, told me that a "speed sensor" was triggering the engine shutdown. so they changed it for me. I asked them about the code 19 thing about the kickstand switch and they explained that the triggers for code 19 may come from 5 sources, one of them being the speed sensor. and from their computers, they seem pretty sure it was the speed sensor, but did caution that with electronics there were many things that can trigger each other, and that there is a chance that something else was the problem instead. (they did say my battery connection was alittle loose and said that could be the problem too but their computer shows otherwise)

anyway, just an update. thanks for the replies again

Hello! I know this is a very old thread, but as long as people keep riding these bikes they are going to keep having these problems.

Also this applies to not only the R6, and R1, but also several other Yamahas of multiple years, as well as some atvs.

Code 19 will show to be a sidestand switch error. Possible, but most likely thats not it.

Basically there are 4 different things that can cause that code.

1. Sidestand switch
(probably not the problem.)

2. ECM faulty.
(almost never the problem)

3. Main wiring harness problem.
(maybe, but unlikely.)

4. Wiring going into the ignition switch.
(Bingo! We have a winner!)

Over time as you ride the bike, corrosion can form on some of the little contacts, or turning the handlebars back and forth you can break one of the little wires on the back of the switch.

You can replace the switch,
(Big costly pain in the ass.)

Or, with handlebar turned all the way left, find the wires coming out of the key switch, carefully cut into the outer covering.
Inside there will be either 2 or 3 larger wires, Red and Orange depending on model, (leave those alone! Lol)

...And two smaller Guage wires, usually blue.
Cut these smaller blue wires loose from the switch, strip about an inch, and twist them together.

Youre fixed! Tape everything up and start the bike!

No, it doesnt need a resistor.
No, it will not run the battery down.

This fix works on several years, and models of Yamahas that have a code 19 error, crank but no start condition.

If its a speed sensor the speedometer will not work, but the bike will still start and run.

Neutral switch shows as a code 42,
if it is bad or disconnected you will have no Neutral indicator, but the bike will still start with the clutch squeezed in.
