You may want to look closely at those screws as you maybe able to make an adjustment. If you say that the needle on the VOM moves thru it's sweep at a smooth progression then maybe an adjustment is in order.

Just a fwiw, try it, in the end you can always go spend the money if the adjustment don't work.

It is adjustable. Loosen up both screws just enough to be able to rotate TPS and rotate until you get .54 volts. FSM gives you an acceptable range but gurus tell me .54 is optimal.
