TBW Limp Mode....
 

Pulled these codes this morning after I went into limp mode 5 times last night on the way home from work.

P0120, P0123, P0220, P0222

Cleaned and greased the connector behind the AC this morning and it took it for a spin... Seems to have done the trick but I think I’m going to change out pins and connectors anyway just to be safe.

This is the 2nd time I’ve dealt with this but I got different codes this time.

I’m reading 08’s and 09’s are notorious for this issue.

Not a Throttle By Wire Fan at all!

I like the clean look of the TBW but when it acts up it's a pain. I had a problem but don't remember the codes after changing bars. there's a connector inside the bars that seems to give problems.

the throttle twist sensor connects to a wire that connects inside the fairing/headlight

I don't remember the codes either, but you cleaned the pins and problem went away, good chance you found the problem.

You said this is the second time … did you change the pins the first time?

Cleaning is only a temporary fix.

Just a suggestion, when you replace the pins add about an inch to the wires. Beside the fretting problem those wires are way short and can get stretched and break.

Yeah I’m going to change them out... Insurance

Also, put a big shrink tube over the connector. HD has done this since the ‘14s. I’ve got a roll of shrink tubing that fits. Its stuff, but it works. PM me if you want a chunk...for $free.
