code p0122 please help translate
So, found the awesome instructions that showed me how to get my bike into diagnostic and I pulled up code p0122. I know it's listed as TP sensor open/Low EFI.
I know TP is throttle position sensor and EFI is electronic fuel injection. But to be honest, that's about all I know. Does TP sensor open mean it's disconnected? Low efi-does that mean low fuel getting to engine?
A little history on the bike, maybe it will make more sense. It's an '04 FLHTC that I picked up as a wrecked bike. Pretty minimal damage, mostly just cosmetic(all the painted parts). Engine wasn't touched at all. It looks like the guy who crashed it did take off some stuff. I know he at least had some pipes he took off but not sure what else may have been removed(i.e. tuner).
Bike starts up great. Idles ok for a while and then kinda rough when it's warmed up. Hesitates a bit when you roll on the throttle. Of course, that could be from the gas that's been sitting in the tank for the last 6 months.
Any ideas? Is it maybe something I can fix? Or should I just take it to a shop?
thanks a bunch!
