Its Back!!!! Throttle body code

Went to fire up the spyder this morning for a ride to work and as soon as the key was turned I knew there was going to be problems. The engine and gas light were flashing together, fired it up and limp home came on. Checked the codes, P2620 and P1120.

Had it replaced in 2015 and have only put maybe 4,000 miles on it. I really hope I don't have to pay for this crap again. How many does it take before I won't have this problem?
 
Since the bike doesn't get ridden a lot: perhaps the throttle bodies just need a real good cleaning. :dontknow:
Check with your dealer; good luck! :thumbup:

Dealer is closed today but I'm going to check a few things when I get home. It's done it a few times since the replacement. But after it sat about 5 minutes it started up and ran ok. Not sure why they have those little quirks. I'll check the connections and try to clear the codes and see what happens.
 
Sorry... :banghead:
The earliest of the "throttle by wire" bikes just seem to be plagued with this issue. :gaah:
By the time they got to the 2013 model year: it had pretty much been resolved.

I mean what is the main issue? What was changed when the 2013's came out?
 
Hopefully I get my bike back tomorrow from my second throttle body replacement. The last one was last year July (circa 13K miles on the last replacement). The dealer says they are in revision 4 on the throttle body's.

Did you have to pay to have this 2nd one installed? Would this new one be the latest revision of the throttle body?
 
Newest part number

The latest Throttle Body part number is 420686292. Do you know what the part numbers for your previous units were? I don't know exactly what the differences are.

No I don't have that information anymore. It was back in 2015 so I'm not too sure if they have revised since then or not. I know one thing, this is getting old. I really don't want to start over paying for a newer one but if i have to, to keep my sanity, I will.
 
I got the throttle body code one time on my 2013 RT. When I stopped at the next dealer I came to he checked things out. One of the repair instructions is clean the throttle body. Apparently gas leaves a coating in the throat that causes the butterfly valve to get stuck. After I got home the local dealer ran some Yamaha brand fuel injector/carburetor cleaner through it. The tech said they found the Yamaha cleaner to work really good for such things.

Try running some injector cleaner for a couple of tankfuls and see if that helps. For some reason I'm thinking the change from '10 to '13 involved a stronger solenoid to operate the butterfly valve. Even though the fuel ports are below the valve apparently there is enough vapor or spray thrown around that it helps.

You don't understand, when these codes pop up it puts the machine in limp home mode. And when it's like that it either shuts off immediately shuts down or it will idle really rough for a few seconds and shut off. There is no running a few tanks through it with fuel cleaner. I run the highest octane available anyway, which is 93. And I use marine sta-bil every other tankful. So I don't think it's the fuel, it's the machine itself, either the throttlebody, TPS or one of the connectors for these parts.

I was at the Deadwood 3 wheeler rally last year and had it replaced up there, just under $1200. And no, this one I am paying for also at the local dealer circa $1350.

The original Throttle body lasted 25k miles and the first replacement last year circa 13k. Lets see how long this second replacement lasts.

The throttle body part number for last years replacement was 420686292. Will have to wait for my bike to get back to see what part number they put on my bike this time.

I think that's ridiculous that you have to pay for the replacement when they know it's been a problem for so long. They covered the part on mine but I had to foot the labor. Which I didn't agree with but seeing it was the first time plus it was out of warranty, I sucked it up and paid. But if the replacements are defective, they should cover everything. To me that would be a good customer service move to keep a small customer base happy.

That's the current part # being shown for 2010 to 2012. The newest part # is 420686290 and 420686291 for the 998 engine in the 2013 RT and 2015 RSS. Is the 2010 RT engine the 990 or 998? If it's the 990 then then the -292 part is probably it.

You're right. Now I remember when it happened to me my 2013 RT went into limp mode. Initially it wouldn't drop down to idle speed and I had trouble getting it into gear. I drove a few thousand feet and stopped to check the oil. I thought maybe it was low and was causing the shifting problem. When I restarted the limp home mode cleared and I was able to drive something like a hundred miles to the dealer. I never did get the TB code again. That's why I'm thinking you might be able to remedy the problem with fuel cleaner.

the Yamaha hualer carb cleaner , I wonder if they sprayed the carb injector area liberally cover the moving parts and cleaned then that way , or ran a container full through the gas tank ? { the service tech guy that is }
