I have a 1995 Nissan Quest. I want to locate and test the "vehicle
speed sensor".
Where is it located on the transaxle?

The Haynes manual has a picture that implies it's located at the
top/rear/right of the transaxle as you face the vehicle, but I can't
find it.

I've also looked to the left, center, top and bottom and I can't find
it. I'm sure I've looked right at it, but I can't seem to identify it.

All tips, suggestions, and comments are welcome.

TIA,

Manjo

I believe the Quest's VG30E (3.0L V6) engine is the same type used in
the earlier Pathfinders.

Found it! top/rear/center back in the shadows. Has anyone taken one
out of their trans? Is it a force fit, or is the sensor threaded into
the transaxle??

TIA,

Out of curiosity: Why do you want to take it out? IF it is an auto,
the transmission will not shift correctly. If it is a manual, the check
engine light will come on.

If your speedometer is not working correctly, the sensor is more than
likely NOT at fault. You CAN find the feed to the speedo from the sensor
and check for a signal. When the speedo goes bad its one of the IC's and
it isnt replaceable even though its a cheap part.

Search this newsgroup for old articles about this.

Speedy,

The speedometer appears to be working OK, BUT the tachometer is and has
been "broken" since I was given the car 3 years ago.

I have tested the two-wire speed sensor connector and I get zero/no DC
volt reading on either wire testing to ground (the test procedure is
from the Haynes manual). Since I have not been able to take out the
sensor itself, (I don't know if it's a force fit or threaded into the
tranny), I'm assuming the sensor is OK.

I guess my questions are the following if you can help me:
1. Is the vehicle speed sensor threaded in to the tranny, or just a
force fit?
2. If the speedometer is functioning correctly, will a broken tach
have any effect on the information passed to the various solid state
components in the car?

TIA for any info, tips, suggestions, (and Happy Turkey Day!)
