Default 05 TPS voltage

I think the TPS on my 05 is going out, but I want to test it before replacing. Does anyone know the voltage readings at closed and wide open throttle?
Thanks.

TPS is measured with resistance, and not voltage. That said I have never had one fail a test, and yet I have fixed a bunch of bikes by replacing one

I'm not an asshole...I just type that way

So you think I should replace it without testing the readings?
I read an article about using a multimeter to test closed throttle through wide open voltage....but I don't know what those are for my particular application.

Randomly stalls during taking off or coming to a stop, surging when staying at one speed.

Yes I have cleaned the throttle bodies, cleaned the air filter, changed plugs, did a hard reset on PC3 and reloaded the map, checked fuel pressure.
I'm really running out of ideas on what the issue is. Figure $35 for a new TPS is worth it, but I want to check the readings first.

Sounds like you may be running lean with the surging. You may want to consider adding a fuel controller . I had similar issues with my Kingpin surging at slow speeds and shutting off when stopping on occasion. The fuel controller cured that. Also had a bad tps. I would have almost like a flat spot just off idle, very slight. I checked the tps for resistance, not voltage. Can't remember exactly but the resistance should either increase or decrease as you open the throttle.I had a small drop off just off idle, right where most of the wear will occur. I was told a bad tps on an 04 was uncommon, mine was bad. I'm sure more members will chime in, good luck.

If you do remove the tps one of the screws is real hard to get at. Just drill a small hole threw the corner of the airbox to slip the allen wrench thru, easy enough to epoxy the holes when done.
