ok I did a lot of searching and found great info, but i wanted to know if any of you guys had a problem like this.

When I drive my 4th gen lude my speedo would jump sometimes. it jumps randomly and sometimes it just goes to 0mph then go back to normal, but most the time it works fine. My car would work fine so i didnt think nothing of it ... just thought it was just a wiring problem.

well after getting my knock sensor replaced i havnt had a CEL for a while but i noticed that once in a while it would come on when i run my car hard. but when i turn her back on the CEL goes away, so today i finally checked it out to see waht was wrong and it was code 17 which is the VSS. so now i know why my speedo was acting up.

i didnt a couple searches and now i know where its located, but i want to know for sure if its the VSS sensor or VSS circuit.

anyone have any idea?

well why don't you pull it out of the tranny and take a look at the differential gear on the end to see if there's obvious wear. It's easy enough to pull it out.

The connector for the VSS is vertical, so it's very easy to have water just sitting there and going down into the pins and corroding them. I bet that's what's happening. Try unpluggin it and pulling the VSS out and inspecting it closely...

Odd enough, even though the Helm's shows that the connector is vertical, mine was horizontal (93 H22)

Also, for me to pull the VSS out, I needed to undo the cable brackets on the tranny too.

Just take it off and inspect it like stated before.

SoOHiGH

ok I tohught i would be able to find it myself but i cant.

can someone show me where its at in these pictures? or can you tell me where to look because i cant find it.

Greyout

well my image hosting isn't working, but if you look at this picture, and follow the two parallel hoses in the upper right, it will lead down to it. The 2 that do like a 90 degree curve, that are 3/8th"s or whatever thick.



they are # 29 & # 12 in this picture


they go to that un labeled, grey'ed out thing, which, is the VSS, and looks like #8 in this picture, and is held in by #14:



careful, #14 breaks easily. leave the hoses attached, otherwise Powersteering fluid will get everywhere.

hope this helps.

SoOHiGH

i found it but i cant get to one of the bolt

Greyout

there is just one bolt, you need a long *** extension (or several of them), and a wobble socket helps

There's only 1 bolt holding it down, but you'll need like a foot and a half long extension to get it after you unbolt the shift linkage and move it aside. Shift linkage has 3 bolts...

SoOHiGH

i think i see 2 bolts. but anyways ima try it right now before the sun go down.

thnx for the quick replies guys

Greyout

I only remember one, and the picture shows one, but alright... good luck

prelittlelude

if you see two bolts your messing with the wrong thing. there is only one bolt that holds the vss down.

if you have ever shifted hard you can break the metal peice that the bolt goes thru, and the vss actually will pop up out of the tranny.

it was funny when i undid my vss bolt and i took the bolt out and along came a large chunk of the vss that the bolt goes thru. come to think of it that is still broken .. hmm

likely if you shift hard you broke it, its a very common problem

oh and THERE IS ONLY ONE BOLT!!!

SoOHiGH

well maybe the previous owner installed a different VSS? because i have 2 bolts

is this it?


the metal piece inside dont look bad so i guess its the sensor thats messed up?

SoOHiGH

maybe i dont got a h22 tranny .... i am the second owner.

Greyout

lol you just took it apart...

the other 4/5ths of the sensor is still attached to the tranny...

AGAIN IT LOOKS LIKE THIS! #8!






theres a little tiny gear at the end, that runs off the ring gear on the diff.

SoOHiGH

but the helms shows this

prelittlelude

well yeah if you look in the section that shows you how to disassemble the vss.

look at the tranny removal section they should show you it right there.

you just took the top haf of it off, the whole rest of it is still in the tranny held in by one bolt, feel down lower its the thing the two smaller hoes are attached to and everything below it

SoOHiGH

if i take the whole thing out would the power steering fluid get everywhere?

i see what you guys are talking about now. i see the one screw, but if i take it out what should i check for? the gear on the bottom?

prelittlelude

you want to make sure the whole assemby is broken , also want to examine the condition of the gear, and if you take the hoses of then yes power steering fluid will come out, just plug them with a bolt or golf t

here is an expanded view, you need to remove #10


edit: part number 6 is ususally what breaks and is what alows the vss to lift up and lose contact with the drive gear on the differential, hence you have a bouncy speed reading or no reading at all

Greyout

as you lift the entire assembly off the transmission, you will notice the end is wet with transmission fluid. Because it goes in from above, none will leak out other then maybe a few drips off the VSS gear.

You should look to see if the gear is broken. If the gear is NOT broken, then perhaps it wasn't seated properly. If it WAS seated properly, then something inside has broken, and you shold get a replacement from a junkyard.

You can inspect it without loosing any PS, but if you need to replace it, you'll have to remove the PS lines eventually, and loose some fluid.

SoOHiGH

i unscrewed that 1 bolt but the damn thing wont budge. i cant take it off now. any idea why it wont come out?

Greyout

grab it and give it a good wiggle, it'll come out
