Confirm a bad TPS 2010 850 XP EFI

Pulling my hair out with these 520194 codes, I get 520194 -2, volts over range, 520194-3 volts high, some -4 and some throttle cable adjustment -7.
Did a few adjustment on the TPS with my 5 volt tool but seems the error code and actual reading just done jive. Not with throttle body off and jumpers on at least.
Had only 2 good rides in my recent Nov hunting trip, and limped back to camp a few other times.
So I did do the ohm check on the 3 pins as the test procedure suggests, but it does not specify how far out, if any on the ohm check that would confirm a bad TPS, anyone know how far off on the specs to confirm a bad TPS ?
These were my readings,
Pins 1&2, throttle pins closed, spec 4-5 k ohm, I got 5.3 k.
Pins 1&2, throttle pins open, spec 1150-1250 ohm, I got 1900 ohm.
Pins 1&3, any position, spec 4-6 k ohm, I got 5.67.
2 seem ok but the 1900 ohm seems too far off.
Any thoughts ?

Ok, won't know this for sure til spring, but I was pulling my battery for the season before the cold snap hit here in AB, and my battery post screws were not very tight at all. So this may have been the cause of the TPS voltage fluctuating so I'll know for sure in March or April.

That could've been the cause, these things (xp or sp) are finicky.
