Hell's yeah. When you get in to the app with the bike on and you are connected with the bluetooth there is a View Sensor Data button. Go in to that and at the top right there is a TPS position reading. It should be at 0 with a proper TPS. If it doesn't say TPS in that circle then you need to select one of the circles in the corners and change it to the TPS reading.

It's a bad sensor somewhere or a frayed wire on you 5V sensor voltage. You could unplug them one by one and check the 5V to ground on the connector to rule out sensors. I'm betting on the temp sensor.

I have a multimeter around here somewhere. How would I go about testing? Is there a guide I can check out?

I tested it and it registers 5.11 ohms. The one on the bike registers at 4.09. Safe to say it's bad and replace?
Also, looking at the manual the TPS and MAP seem to share the same 5v Sensor Power, this could be why the MAP code and 5v code are coming up, if infact the TPS is bad.

Good deal.
One of the screws is easily accessible, the other only gives about 3/4 inch of room between it and the head. I'm going to have to go check around for something smaller to get that one out.
Thanks for the help, I'll give it all a go and let you know how it turns out.

Have you cleaned the air flow sensor? There is a hole in your intake manifold that may be gummed up. My 14 fxdl was doing the same thing. I cleaned it an it got better. It eventually happened again so I replaced the sensor and issue was resolved.
