dc2r speedo not working..need help

[sai_vang]

hi all, yesterday me and a friend top up the transmission oil into my dc2r. we took out the speedo (i think thats what its called) in order to put the oil in. however when taking it out we didnt know that we could take the speedo out in one peice, instead we took the top part of the speedo out first then we had to take out the bottom piece aswell. However after we had finish putting in the oil and we put the speedo back into place, the speedo thingy in the dash wouldnt work. the rev and all the orders seem to work fine except the speed thingy.

in the past i've had the speedo playing up aswell.. sometimes it would stop working will driving and after a while the speedo will start workin again. However it has been a while since the last time it was doing this.

does n e one know what might be the problem here? could it be the speedo (attached to transmission) that is faulty??

Is it best to take it to a honda dealership to get it checked out?

all advice and suggestions welcomed...

I think you meant the speedo cable?

[neut]

its ur VSS(Vechile speed sensor), ive had mine replaced twice(top bit only, not the whole thing) in the passed week and its still playing up, it actually dies on me. This time im getting the WHOLE thing replaced sucha hassle! aprrarently there really sensitive and easy to get faulty so becareful next time! got mine ordered at essendon Honda...getting it done 2moz! anyways goodluck! nice car Blk Shadow looks mint @ the front of the shop ;)

I've always wondered why people put their oil in through the speed sensor hole. On my YS1 there is a capped hole at the top for oil - seems insane that the DC2's would not have followed with this.

ive always been meaning to check that capped hole on my y80 string,& find out where it goes to,but never got around to it,must remember next time.

for the OP,make sure u didnt lose the little drive pin between the 2 pieces of the VSS,its about the size of a third of a match stick & easy to not see it drop out when u take the 2 pieces apart.

If you are forced to put the car on jackstands to drain the MTF out and open the filler bolt to find out when you have refilled enough fluid, why not just use the proper filler hole to fill MTF instead of messing with the VSS and vent hole??????

but that vent hole is nicely positioned in my car aarong,you could imagine where my filler hole ended up with the different motor,especially when the cars dropped level to fill.Unfortunately i bastardised my honda & its not as easy anymore like they originally designed it to be :(

If you solely use the VSS/vent hole and not touch the filler bolt, how do you know when you have already filled enough MTF?

i still pull the filler bolt out to see the levels,but its a bitch to get to as its ended up tucked further up inside my chassis rail & would be nice to just drop a hose down thru that vent hole.

Ahhh, okok. But it does seem to be more exposed on cars with their stock engines. Even mine is in a tight place, but there is still a way to manuvere a tube into the filler hole.

[string]

I open the filler hole then start the pouring and stop when it dribbles out. I honestly can't think of a faster way to do it - but maybe you just like a challenge :)

this also works for your gearbox , actually most if not all manual honda gearboxes :)

EDIT to keep it on topic , original poster - taking the VSS apart wil expose the internal lug , this can easily fall out and go missing. without it the speedometer wont pick up and wont work. retrace your footsteps and take the vss back out , check the connection , check the internals and make sure everything is fine/working before you take it to a profesional for a proper look

Doesn't work with my manual gearbox, which does not have a VSS on it. LOL

yup but you do have a similar hole above that can be removed , filled from in the same manner ? Have alook and help out the k series guys.
Anyway filling from the vss hole on a b/h/f/d etc ensures the exact amount is in the gearbox specified from honda. (on flat ground) once the level is surpassed the excess leaks out , once it stops dripping that is the correct level :)

Will check, but for at least the Euro owners, they rather not fill through the top of the gearbox because that requires the airbox to be removed to access it. more trouble than it is worth it.

What I don't get is that if you fill through VSS, you still have to level the car, open the filler bolt and fill up til it leaks out. So you might as well fill it through the filler hole in the first place since you have already pulled the filler bolt out.

[bennjamin]

this method i made up (in my world , it DOES exist earlier and elsewhere im 100% sure lol) due to the actual filler hole being too small for most normal hoses to sit in easily. Also once filled it would often spray out giving inaccurate reading , plus watching multiple mates do this on my front driveway and spill mtf everywhere convinced me to clean up the act.

So the overall best way IMO is to fill via the vss and watch for the dribble out hte fill hole. you only need to watch from above for the dribble and you are done.

[CRXer]

but what about the vent port ben,have u ever tried that?

i wanna know how big the hole is into the gearbox or is it just a tiny hole at the botoom of the port that would take ages to fill?

plus to get it off all u have to do is simply remove plastic cap.

It goes down pretty slowly.

[bennjamin]

It goes down pretty slowly.

yup exactly , its a tiny hole on my s80 gearbox for example , similar on others im sure. As string said it goes down very slowly because the vent leads to a small chamber then leads to the guts of hte gearbox. The thick fluid has to fill this chamber and then lead down so its a slow slow process.

[CRXer]

damn it,that woulda been a nice solution,ah well back to the VSS

[sai_vang]

thanks for all the suggestions.. we did notice the little pin inside the vss and we did out it back in.. still doesnt work...

anyway today i was driving and sometimes it starts working for a couple of hundred meters and then it dies again... it has done this about 3 times today.. could it be a faulty VSS... i called yarra honda and the guy said it'll cost me $99 to diagnose the problem.. then the part and labour cost are extras...

Should i just buy the VSS and change it myself...

before it gets to this....do you have a friend with a similar or same car ? try and borrow a VSS of a known working one and see if you get the same issue.

[neut]

sigh its clearly the vss, why check up on it and waste 99$? its the VSS, if u leave it for abit more ur engine light will come on and ur engine rev will sit above 1000rpm, ive had my problem for almost 2 weeks now and weds im getting it done, also done a ECU check and it gave me the code leading to faulty VSS. Sai Vang im having the exact problem as you lol, but mine now is actually DEAD. the 1st week was up and down, now its dead. order the VSS from your nearest Honda Dealer and get it done :) goodluck

could also be an intermittent contact fault in the plug,mr instant expert,which part of the symptoms described makes u so sure,im keen to learn?

Told you ive had the same problem, and dont act all cocky CRXer 'mr instant expert.' im not implying that im an expert.. i just dont want anyone to waste 99$ just on a check up where the problem is evident. My problem is exactly like his and ive had my check up and its def the VSS problem. if you want to check your Cluster if anything is loose then go ahead, you'd be just wasting ur time. My Mechanic checked it for me (@ Hondatec) and hes certain thats the VSS. At the time he only replaced the tip bit where the wire plugs into but now hes replacing the whole thing. well goodluck with yours sai

[sai_vang]

thanks guys... yea my bro in law has a dc2r aswell...so i might have to take his vss out and try it in mine.. if it works fine then i'll go change the vss...

thanks for all the advice and suggestions...

the problem being is u contradict yourself,your telling the guy to go fork out on a new VSS,but u dont want him to go & get it checked,without being entirely sure of what the problem is yourself.

he has not described CEL's or over reving of the coasting idle,so how can u be so sure the problem is exactly the same as his.

the only functions of the ECU that rely on VSS are the coasting idle & VTEC.
a simple short caused by crap buildup in the plug thru careless handling could also fool the ECU into a speed indication &/or CEL's.

the same problem from a bad connection in the plug could cause a dying/intermittent reading of the speedo.

hell,he could even ask nicely & there are quite a few people on this very forum alone who could guide him thru the diagnosis himself with a $10 multimeter purchase,instead of going out & buying a new VSS,which could be just as useless.

good cheap way of self diagnosis,if its that readily available.
