1993 Nissan Quest Broken VSS

Hello -

Okay to make sure I am helping you correctly. . ..is your model just the Quest, or the GXE or the XE? Also what is your engine size in liter?

I have attached the directions for removal and testing. . .. . .. . .. . ..just to have with us.

Next, based off the pic, I am trying to understand what is broke off and what is left in the trans. . .. . .

Is the part with the red circle still in the trans?

SPEED SENSOR
1. Remove speed sensor from transmission. See Fig. 3 . Turn speedometer pinion quickly and measure AC voltage across sensor terminals. If voltage does not toggle at about .5 volt AC, replace speed sensor.
2. Remove instrument connector. Measure AC voltage at connector terminals No. 32 and 30.
3. Turn ignition on. Spin speed sensor. If .5 volt AC is present, replace speedometer instrument. If .5 volt AC is not present, check continuity of related circuits and speed sensor. Repair as necessary.
CAUTION: Ensure pinion shaft is properly seated when installing speed sensor. Speed sensor thrusting key should fit into groove of pinion shaft.

Hello -

Thanks for the info and pic..... Thats great.

Many times the spline is plastic..... Others metal.

My suggestion....... Jack the front up so there is no pressure on the transmission. Put in neutral.

Spray some penetrating fliud in there and let sit a sec...

Then try a magnet if metal or the screw again and gently wiggle to see if it will release from the opposing gears.......

Let me know.

I am not sure what to expect if you pull the housing out. Do you have the new VSS? The pic I looked at on line looks like the VSS just slides into the part in the trans.

My concern with driving it is the gear is basically loose and floating...

Did you try as I suggested to pull it out?

You shouldn't have any leaks.

I am going to ask one of the other moderators to take a look at this also to see what they think about the housing.

In the mean time....... Again, did you try as I suggested?

Hello -

Doesn't look like the other moderator is up......... Sorry for the delay.....I will request a couple of others.......

From the diagram, the speed sensor and meter driven gear looks like 2 separate item for the model shown. There are different model sensors, some comes with driven gear as an assy while others are separated into 2 parts. The single assy type would be all black plastic and would come out as an assy.

If you pull the housing out, it would be the housing and the meter gear only. To pull it out, prying and twisting makes it easier. Check for any locking bolts at side of transaxle housing along meter gear position. Nissan tends to have the bolt to hold the meter gear. Do not worry about pulling it out, it would come out as an assy and installation is by plugging it in only.

Check for worn gears. If gears are worn, it would cause none or erratic speedometer functions. Always count the number od teeth and measure diameter of replacement parts, wrong part used would cause the gears to wear off prematurely.

When installing, do not force it in, gently twist and tap it in. If it is remove, trans fluid would splash out if driven.

Were you able to repair your vehicle?
