TPS - Throttle Position Sensor

So i've been trying to do my research and I havent really been able to come up with much. Do these 05+ trucks only have one sensor? My wrench light has been coming on here and there and i've been using my friends Auto Engenuity to pull the wrench light soft codes and its for the TPS. The other day while driving i was going up a hill and all power was lost, my accelerator was not working. I shut the truck off and turned it back on and was good to go.

I did read somewhere that there are 3 TPS sensors and if one sensor was bad it would throw the wrench, if two were bad the pedal would act finicky. Is this true?

I'd like to know so I dont eventually get stuck with a trailer attached working.

There are three different sensors on tousley parts which leads me to believe what i read is true.

Thanks

all three sensors are in 1 TPS sensor. it has seperate circuits to this sensor. so the TPS sensor will have 6 pins(not sure on pin count) there won't be three seperate sensors. Just three sensors inside one plastic housing hope that makes sense. They do it this way just so the ecm can keep on eye on things 1 goes from low voltage to high, the other goes from high to low and the last one i forget how the voltage goes lol.

ahhh explains a lot and rids any confusion. Do my symptoms sounds accurate to a faulty TPS?

The tires leading to my sensor looks like it is spliced into.. for some odd reason... im guessing this is NOT normal

oops, typo, but there was only one code, I cant for the life of me remember the darn code.

the wires that lead to the sensor on the pedal are all spliced as if they cut and spliced in a new pedal/sensor from a used truck
