I am by no means an expert, but I suspect what you are seeing are a string of all the codes that ever came up for the bike. If you clear the codes, turn the bike on, run it, shut it down and check for codes again. I suspect you will be left with the true code you need to investigate. I did a quick search for the codes and any code starting with a P is fuel system related.

Agreed with the thought of Hillbilly312.
Clear and see what comes up and then pursue that fix.

 

Don't delete the codes until the bike is fixed...mechanics use the codes as an aide to repairing the bike...if the bike won't restart that a good reason alone not to delete the codes...

 

Bike starts fine and idles fine. It just won't let me give it any throttle.

I agree with the above, clear it out, and if it gives me another code that is the one that is giving me problems. From what I've read, they are all historical codes stored.

 

Have you checked the twist grip sensor?

Not yet. All I did yesterday afternoon was go through what codes had been thrown and they took me home. I'm going to head into town this evening and clear the codes, clean the connections and throw some dielectric grease in with them, then start generally looking things over for any loose connections.

Would that be in the Twist Grip itself? Or down by the Throttle Body?

 

Twist grip itself. The end will pop right off so you can take a peek at the connection.

Reset the codes, started it up, and it sent codes again.

About to go for a test ride and see what it does.

 

Went for a ten mile ride, ran fine, no issues. I got on it a few times, rode on the highway and in town. Got it back and a few more codes showed up at that point:

P0120
P0123
P0134
P0154
P0220
P0222
P1511
P0031

Guess it's time to call the dealership and see what is going on.

 

You have TPS errors, O2 sensors stuck hi or open. O2 heaters not working. And running in PM mode.

Unknown tuner worries me. But I'd prolly start with the TPS diagnostic ladder.

 

SOILRIDER, Thermodyne is right on the money. It seems to all be pointing to the TPS and throttle. You might try unplugging and reconnecting the TPS cables.
Here is what your codes mean:
P0120-TPS1 Range Error
P0123-TP Sensor High EFI
P0134-Front Oxygen Sensor Inactive/Open
P0154-Rear Oxygen Sensor Inactive/Open
P0220-TPS2 Range Error
P0222-TPS2 Low
P1511-EFI Power Management Mode
P0031-Oxygen sensor heater Control Circuit

 

Thanks for your replies!

Where should I start? I have disconnected the plug behind the intake, and reconnected a few times. Is there a process to reset the TPS? I had an FI Race ATV that I knew the ins and outs of. BUT, I'm not to excited about taking off a fuel tank on this, vs the plastic fuel tank on my quad. Can I find information pertaining to this in the Service Manual? I have a copy of it.

What would be the best plan of attack? I would prefer to do majority of work on my own, just unsure where to start. Real new to the electronics on a Harley, where as with my quad I knew every square inch of that thing.

Thanks,

Kyle.

 

Any luck finding the limp mode problem? My 2010FLHTC went into limp mode the other day. I disconnected the battery for about 15 min., restarted it and it seems to work fine. I have no idea why it went into limp mode or how to retrieve codes but am happy it works again. Like you, I'd like to find and fix the problem as I do my own work and am far from a dealer.

 

Codes



You can retrieve your codes by having the ignition off, holding the trip reset down, and then turning the ignition on while still holding the reset down. Once the display comes up you can scroll through the menu to see if codes exist.

 

Sounds like it could possibly be a TBW sensor issue. Be curious what it turns out to be.
