I had to replace my TPS today. I have done about 2 hours worth of searching and haven't come up with a wide open voltage. Idle is .98 but WOT is 4.62. All of my other vehicles are 4.8-4.9. Is there anything to be worried about at 4.62?

 

Id try to get it a bit closer to 5.0 But dont go crazy trying to get it there, as it isnt THAT critical.

What year is the truck?

OBD-I uses a "relative" throttle position sensor readings.

So once the EEC reads closed TPS voltage, then WOT TPS voltage, the initial voltage readings go right out the window.
