I have another question about a tps,
-when testing for voltage on the senor itself am i suppose to get any
reading with throttle full closed? and what should it be half way open?
fully open?

I cant remember exactly(closed .5V and 4.5V WOT?)

.5v when closed and 4.5v at wot

and inbetween is determind by where the throttle plate is

thats the rule of thumb tho
some cars are at 4.6 4.7 at wot.. so its all on the manufacture
but i beleive honda is at the 4.5 mark
