yes it's worth fixing. registering /any/ replacement vehicle is going
to cost you more than $40. you can buy just the sensor from a junkyard
or the whole throttle body. google these honda groups on how to replace
just the sensor. you can even do it with the throttle in place if
you're careful - minimal plumbing that way and no gaskets. if you
remove the sensor yourself from a junker, it'll be practice for how to
replace it on your own vehicle. get a sensor from an automatic -
significantly less wear. write back if you get stuck.
