what's up guys dave here if you're interested in resetting your throttle position sensor on your
bike this is a 2020 honda grom but it may apply to many other models including the honda monkey
uh we're going to you're going to take the cap off of your little service connection here and you're
going to jump the wires you got the green and blue and you're going to jump them together basically
with a you can use a paper clip or a hard wire of some sort just make sure that it's connected
them together okay and then down here this sensor you're going to disconnect the sensor the harness
from the sensor itself and we're going to jump those two wires as well to remove the clip for
the harness you just press on this tab right here notice how it pulls away from it right there and
just wiggle it and pull it off then we're going to put our paper clip and jump these two together
okay so take your either hard wire or a good strong paper clip like this
connect them together one in one hole one in the other hole
do a little wiggling you know make sure that it gets in there
okay now we'll come up to the ignition switch all right make sure you got to jump there and jump
there make sure your kill switch is in the run position we do not touch the throttle this time
and now as soon as we turn the key on the check engine light is going to flash
pretty quickly as soon as it starts flashing you want to
remove the jumper down at the sensor at the bottom okay so switch on watch it
starts flashing pull the jumper starts flashing fast
that means it was completed
notice if it's starting to flash fast like that that means everything was completed properly
shutter back down reconnect everything remove your jumper wire over on the side remove that guy
and we want to do all this while the engine is stone cold remember that anytime you're doing
any resetting of electronics and computers and whatnot on a vehicle any kind of efi vehicle make
sure that the engine everything is stone cold before you restart the vehicle okay and i don't
know if it's the same on these but i know in a lot of cars after you remove your remove all your
jumpers put all your stuff back together
put your sensor wire
back in place make sure you hear it click in place uh now i know on some cars
you um you know we'll turn the key on and you'll listen you'll hear the efi you know
make some noise you'll hear it buzz a little bit it'll also you may hear the uh the butterfly
of the of the throttle body move a little bit that means it's resetting its trim to a default setting
we want to wait for all that to occur so that might take a full minute
to do properly so i'm just relating to this what i've done on on many cars doing like this so let's
do it now kill switch is on run switches on we're not going to start the bike let's just listen
i'm going to wait for a good 30 seconds before i do anything
okay it's been about 30 seconds uh next thing when you start the bike don't touch
the throttle or anything just let it idle just let it run uh do that for a good couple
of minutes actually just let the bike idle on its own uh you know if your bike will not
idle properly you might need to install your little idle adjusting knob which is a common
you know upgrade item on this bike i got previous videos on that on my
on my channel anyway kill switch on no throttle let's just fire it up and see what happens
okay i'm gonna build my idle speed a little bit
the aftermarket idle adjuster is quite handy to have
this little knob right here replaces the stock idle adjuster screw which is on the other side
of the throttle body and it's you know it's not the easiest thing to adjust on this bike manually
so i do kind of recommend uh but make sure you look at my previous videos on
some slight caveats on installing that adjuster anyway we're gonna let the bike
idle on its own you know go for a good couple of minutes and uh then we'll go from there
that's the same on any fuel injected vehicle you know once you restart it after resetting
everything you turn the key on or you turn your ignition on or you press your uh your push button
on your car you know push it to the on position and you'll hear things resetting and recalibrating
and that sort of thing then you'll crank it up just let it idle for a good five minutes
and then after it's you know getting warmed up then you can go ride it or drive it if it's a car
go drive the car around very gently you know not romping on it just go drive it gently and nicely
for you know gosh for for quite a while actually
just drive it gently and what you might notice is uh it just starts doing things
better you know on an automatic transmission car it may start shifting better and smoother
you may hear it just idling a little better smoother cleaner i mean it's
really it really depends you know it's not going to work for every single situation
but i have done this on quite a few bikes and cars for that matter there it goes starting to warm up
that's been just a couple of minutes
showing about 1900 rpms right there
so i'm at and this is the first time i've done this to this particular bike so i'm actually
showing some improvement already for what it just showed me right there so i'm very pleased so far
all right we're going to leave it about there right around 18 1900 rpms
let it continue warming up just sitting here so then if you're in your garage make sure you
open your garage door and run a fan pointing out too so you don't die of carbon monoxide
anyway we're not touching the throttle we're not doing anything and we're just letting it idle
and anyway so that's pretty much it and you know after you get out and just ride around
some just ride gently ride carefully you might notice after uh you know after maybe
10 15 miles after everything is fully warmed up you might notice some improvements on various
things you know as far as running of the bike so you know try it out you can't hurt anything
i know everyone asked a question you know can i do it on this model this year this
make just try it try it on any particular model you're not going to harm anything
just make sure it's all done with a stone cold engine and that's pretty much it so
so uh yeah check out other videos we've got more stuff about this bike and other bikes
