How To Replace The VSS

how to replace the VSS

I could not find the tutorial for VSS replacement. So, I used the Helm's manual, and the instructions on the replacement part to figure it out. I've attached an image of the part installed on the car. Hopefully this image, and the following notes will help others to perform this task.

First, you need to order the replacement part. The part number is 06560-PY3-000. You need a #20 Torx tamper-proof bit or screwdriver. The Torx tamper-free is NOT the same as a normal Torx bit. Tamper-free bits have a hole in the tip. You will also need a 10mm box-end wrench, 10mm socket wrench, and a phillips head screwdriver.

Then, you need to remove the plastic shroud that protects the forward-underside of the engine bay. Jack up the car, and find the oil filter. Remove the 10mm bolts and two plastic buttons that secure the shroud that spans the entire width of the car, and is just forward of the oil filter.

Now, take a look at this image:

The VSS is located right beside the oil filter. First, detach the electrical connector circled in red. Next, remove the single 10mm bolt cirlced in yellow (with yellow arrow). By twisting the whole assembly back and forth, you can withdraw the VSS from the differential. A few drops of oil will spill -- have a rag ready. Then, remove the 3 Torx screws from the top of the VSS. These are circled in green on my image. Finally, use a phillips screwdriver to remove the 2 screws that hold the sensor unit to the assembly.

Replacement is the reverse. I found it much easier to work with the new parts while the VSS assembly was dangling from the two rubber hoses that you need not remove. Be sure to replace the O-ring on the VSS shaft, and the odd-shaped dust seal that goes under the top plate.

The whole job took about an hour... I could do it again in half the time now that I know how.

so heres the run down


what the dash is telling me:

the check engine light comes one after a few seconds of driving (havent been able to track down a place that can scan it for less than $100 because its OBD-1)

the transmission light (D4) will flash once driving no matter what gear it is in

the odometer will act sparatic but most the time will sit at zero


Completely different:
annnnnd the fuel gauge is out. but the fuel light will come on once its low. suspecting its the fuel return and not the float.

not to mention SRS is on...

how she runs:

she will die once i come to a stop while shes still cold

smokes when i pull away from a stop

sometimes after i take a left turn it will take a little while to slip into gear

and once i get into higher rpms she will kick (slipping)

dont know if these are cause by the ECU going into limp mode or if these are signs of transmission failure

so what im trying to say is if anyone know when i can get my CEL (check engine light) and CTL (check transmission light) scanned somewhere besides the dealer so i figure out what the hell is going on!

besides guessing and replacing parts such as the speed sensor

Pic from VSS service post

I also can not see the pic for the VSS service. can someone please email to me?? tsx1962@yahoo.com

also - would anyone know if the VSS could cause hard shifts? The only indication of VSS trouble is a recent one time speedo malfunction - Tranny shifts have been hard for quite some time and since before I bought the car so I am not sure how long - car now has 105k miles and fluid does not smell burnt. - this is the 91 legend

thx

Any way we could get the pics on this post re-upped? I've got a buddy with a second gen, and I'm trying to help him learn how to fix it.

Yes, bad speedo input to the ECU will cause shifting issues.

holy necrothead batman! The original image link was dead so here it is, alive and well. I am buying this part from Delray Acura - Online Acura Parts Store for $88 so that looks like the cheapest so far:
ACURA LEGEND SPEED SENSOR KIT () @ AcuraOEMparts.com - Acura Parts from Delray Acura

BTW this is the #1 search result when you google this whole VSS issue. Just keeping this thread alive.

PS,

It has been several years since I sold my beloved Legend LS Coupe.... But I did re-host the image so that it should be visible again on the first post of this thread.

Cheers, Cap

Thanks for the info on this Cap! Been having this speedo/odo/d4 flashing issue for about 6 months now. About 4 months ago, had my brother (the family mechanic) change out the speed sensor based on what I read on a few other sites. Well, not knowing much about cars, I trusted he changed the right sensor. Needless to say, I was disappointed when I found out the fix didn't work. :wtf:

My wife drives her Legend about once every 2 weeks and just uses a GPS for speedo information, so I haven't made time till recently to do more research. Well, after finding this site and sending my brother a link to this post, we've now confirmed that he changed out the wrong sensor!! :rofl: Apparently he changed out some sensor disk on the driver's side of the engine. Anyway, I have the OEM VSS kit on order via ebay for THE CORRECT sensor. I'll post my results in about a week or so after we finish the work.

Replacement was flawless. Took about 1 1/2 hours mostly because I took time to take out the whole assembly, cleaned it thoroughly, and cleaned the corresponding area under the car. TAMPER FREE #20 torx and Phillips Head #2 are a must! Before the speedo/odo would crap out after 5-10 minutes of city driving. Since replacement, absolutely NO issues with speedo or odo. Thanks again for the great info everyone!:woot:
