1. don't pay attention to trolls.
2. shop around. the part costs $571 from hondaautomotiveparts.com. you
could replace it yourself.
3. shop around some more. afaict, honda use a limited number of tps
designs, and it's easy enough to get another one from a junk yard.
if you find one and fit it, be aware that the reason honda say to
replace the whole thing is sensor calibration. but that shouldn't be
too hard to do yourself. here's how to do it: take a small [fresh]
battery, say 1.5v or 3v, and connect it so the battery is between the
two outer connectors on the tps output - they connect to the resistor
track. then measure precisely the voltage between the middle one
relative to both the outers. the sum of the two should be exactly the
battery voltage when connected. it should be roughly 0.15v relative to
zero if the battery is 1.5v. again, measure this precisely with a dvm.
now, after fitting the "new" [or repaired, which is also possible in
my experience] sensor, position the sensor so that it now replicates the
exact same voltages with the throttle in the same position.
now you have a calibrated tps and you can drive again! usually, the
sensors fail at a point on the track where the throttle most commonly
sits when driving, but it's ok at the idle position so you can do this
measure/calibrate procedure.
oh, and honda usually use shear head bolts to hold the tps on. those
will unscrew if you carefully use a chisel, or even a reverse helix drill.
